Research Strategy:

We began our investigation with inquiries into the respective websites of each company, industry databases, and business/industry intelligence sources. While we were able to identify some requested information, we were unable to locate information on key clients of either company nor the owner of SOAR. Though we identified SOAR'S CEO, the caveat is that it required the use of sources older than our designated period for current sources. We include it in this project because nothing more recent contradicts the older source.

Our search for the key clients of each company began with corporate websites. However, we were unable to find the information on either website. Both companies are private, which means neither is legally obligated to provide that information. Our next step was an inquiry into industry databases and business/industry intelligence sources (e.g., PR Newswire, Hoovers, LinkedIn, Bloomberg, and Crunchbase). However, no information about either company was available from these sources.

Our final step was an attempted triangulation based on organizations that utilize cloud seeding and weather modification services. While we were able to identify clients of these services, we were unable to locate any information related to the identified companies.

We employed a similar method when searching for SOAR's owner. We began with the company website, but the information is not present. As we mentioned previously, SOAR is under no obligation to provide that information publicly as a private entity. Our next step was an inquiry into industry databases and business/industry intelligence sources (e.g., ZoomInfo, LinkedIn, Owler, Crunchbase, Manta, UpLead, and Experian). However, no information about SOAR was available from these sources.

We then made inquiries into traditional media sources like The New York Times, The Wall Street Journal, and The Japan Times. While The Japan Times did highlight the name of SOAR'S CEO, it did not mention the name of the company's owner.

Finally, we attempted a triangulation to ascertain if the CEO and owner are the same using all publicly available information (e.g., case studies, media publications, and press releases). However, this was not possible due to a dearth of publicly available information.

NAWC primarily positions itself as one of the longest-standing meteorological consulting company in the US. Mettech S.p.A. considers itself as a specialist in cloud seeding with great expertise in designing cloud seeding programs and call them as Sowing of Clouds. The requested information is provided in rows 3-10, columns G-H of the attached spreadsheet.

North American Weather Consultants

Mettech S.p.A

Research Strategy

Data regarding the key clients of North American Weather Consultants and the owner of Mettech S.p.A. is not available in the public domain. This is mostly due to the fact that both companies are privately held and are not obligated to disclose such information. This can also be due to the competitive nature of the industry and to avoid poaching of clients.

We started our search by looking for the owner of Mettech S.p.A. through its website, blog, media publications, among others. These sources were chosen as they are most likely to highlight such information in their "About Us" section or "Team" section. The Mettech S.p.A. website does not highlight their team, owner, or founder information. We also tried to identify the same by locating their respective annual reports and investor presentation but since the company is privately held, they have not published such reports. We could only identify a team member name on Facebook saying that Alvaro Martinez Rodriguez manages the company but did not quote the designation. Hence, this strategy failed to yield any results.

We later tried to identify the same by scouring through contact Databases like ZoomInfo, LinkedIn, Owler, Crunchbase, Manta, among others as these sources are most likely to highlight the company professionals name and designation. These sources also proved futile as the company profile did not exist among them. Hence, this strategy also failed to deliver the desired results.

Finally, we examined media publications and news articles that might highlight the name while quoting what they said in an interview or during any conference. For this we scoured through the New York Times, El Mercurio de Valparaíso, El Rancagüino, La Prensa and others but could not locate any relevant news on owner.

To identify the key clients of North American Weather Consultants, we started by looking for key clients of North American Weather Consultants through their respective websites, blogs, publications, media publications, among others. These sources were chosen as prima facie as these are most likely to highlight such information. We could only could locate some general insights stating that NAWC clients are of multiple domains such as water districts, universities, hydroelectric utilities, government agencies, and private entities. We also tried to identify the same by locating their respective annual reports and investor presentation but since both companies are privately held companies, they have not published them. Hence, this strategy failed to yield any results.

We then expanded our research to identifying the same from third party sources like Business Wire, PRNewswire, Hoovers, LinkedIn, Bloomberg, Crunchbase among others, but these reports also did not highlight any information on the clientele of NAWC. The companies did not have a profile on Hoovers, LinkedIn, Bloomberg, Crunchbase and Owler. Hence, due to lack of publicly available data, this strategy also failed to yield any fruitful results.

Finally, we later tried to triangulate the information by looking for water districts, universities, hydroelectric utilities, government agencies, and private entities that use cloud seeding/weather modification products such as UASD, Metropolitan Water District of Salt Lake and Sandy, among others but could not locate any insights with respect to NAWC. Hence, this strategy also failed to deliver the desired results.

Cloud Seeding Technology and the Future

Three different applications for which cloud seeding technology is currently being used are increasing precipitation, evaporating fog and clouds, and reducing hail fall. Three different applications for which cloud seeding technology could be used in the future are increasing cloud cover, increasing raindrop size, and turbocharging snowfall.

Applications for Which Cloud Seeding Technology is Currently Being Used

Increasing Precipitation in an Area

  • Silver iodine is used to induce rain production in areas where there is barely any precipitation and rain is needed for keeping the soil hydrated. For example, a field of crops where there hasn't been any natural rain can use cloud seeding to induce precipitation. The primary methods used to increase precipitation are hygroscopic seeding, which affects warm cloud processes and glaciogenic seeding, which initiates cold cloud processes.
  • During warm seasons, cloud seeding is aimed at convective clouds, which is most effectively done from aircraft by dropping the seeding agents directly into the upper regions of the clouds.
  • One example of precipitation induction with cloud seeding is the 2008 Beijing Olympics, where officials used the technology to ensure that it rained before and not on the opening ceremony, as well as to increase favorable weather conditions for the games. China has the biggest ongoing cloud seeding program in the world, spending around $90 million per year to increase rainfall for farming, and help clear the air pollution in major cities.

Evaporating Fog and Clouds to Keep an Area Dry by Precipitating Out

  • Cloud seeding can also be used for the treatment of fog. Supercooled fogs can easily be cleared by glaciogenic seeding, either from the ground or from airborne application.
  • In fog dispersion, cloud seeding allows small drops to evaporate and then condensate on the seeded particles, allowing the liquid and vapor water to disperse onto fewer drops that grow faster and precipitate.
  • For example, the technology is being implemented around the world for clearing fog from airports.

Reducing Hail Fall

  • Cloud seeding can be used to help mitigate hail damage. Since hail is ice produced by convective clouds, glaciogenic seeding techniques can be used to manipulate such clouds. With this technology, excess is induced to freeze into many small particles instead of less large particles. The ice that precipitates melts during its transit through the warm sub-cloud layer, and the one that doesn't precipitate reaches the surface as much smaller, less-damaging, ice.
  • In 2011, the company Western Kansas Groundwater seeded a 6,766 square mile area in Kansas during the months of April through September to prevent hailstorms.
  • The company Weather Modification Inc. is using seeding techniques to decrease the size of hailstones in order to reduce damage to crops and property in Cheyenne, Wyoming.

Applications for Which Cloud Seeding Technology Could Be Used in the Future

Increase Cloud Cover Over the Oceans

  • Bill Gates is financing a new project to reduce the heat of the planet by increasing cloud cover over the oceans.
  • The project consists of an unmanned, floating sprayer that could throw sea salt specks into the atmosphere to condense moisture. The technology is based on principles discovered by Anton Flettner.

Increase Raindrop Size

  • German, Swiss, and French researchers are developing a laser technique for increasing raindrop size, which is being tested in Berlin.
  • The laser, which power is greater than 1,000 power plants, is fired into the sky, "reconstituting atoms in the air into components that could seed bigger and better water droplets."

Turbocharging Snowfall

  • After decades of cloud seeding research and experimentation, scientists in Idaho have recently demonstrated that turbocharging snowfall can be possible.
  • Researchers tested with supercooled clouds, with temperatures of 0°C to –15°C. Testing whether this approach is economical is still pending.

Research Strategy:

In order to provide the requested information, we searched through sources written by industry experts. These sources include industry reports from Researchgate, company websites like Weather Modification Inc., and reputable media experts like BBC and the American Association for the Advancement of Science. We then synthesized the experts' information into our findings.

Cloud Seeding Effectiveness

Many studies have been published on cloud seeding. The most recent ones have used modeling and simulations to determine that silver iodide cloud seeding does increase precipitation. The cloud seeding technology is not used all around the globe due to the lack of statistics supporting the effect of cloud seeding and the concern for health and safety.


  • French et al. published a paper in 2018 detailing a study on glaciogenic seeding. The study was able to produce precipitation (snow) on a mountain surface from silver iodide glaciogenic seeding. The study used radars (ground-based X-band and airborne W-band) and in situ cloud physics to determine the start and development of the ice crystals from the silver iodide glaciogenic seeding.
  • In 2018, Rasmussen et al. published a paper on the results of a model used to estimate the impact of AgI ground-based cloud seeding for the Wyoming Weather Modification Pilot Project (WWMPP). Their results found that the seeding impact on annual precipitation over the Sierra Madre and Medicine Bow Mountains in Wyoming is about 1.5%.
  • Chu and Geerts published a paper in 2017 in American Meteorological Society about gound-based glaciogenic seeding. The study found that AgI glaciogenic seeding does increase the amount of snow fall in a shallow, largely blocked cloud.
  • In 2016, Lulin Xue published a case study to determine AgI impacts on precipitation. More precipitation is generated when AgI particles are released from ground-based generators. The simulations of the seeding event found that the seeding effect ranged between 5 and 20% over the Medicine Bow Mountains for different grid spacings.
  • The Wyoming Weather Modification Pilot Program-Level II Study published in 2014 found that there is a positive effect from seeding between 5 and 15%.



  • The lack of implementation stems from the lack of rigorous statistics. These weak statistics are caused by the nature of these studies. When a cloud is seeded it is now impossible to determine whether that exact same cloud would have rained or snowed.
  • The effect of cloud seeding is hard to determine, despite constantly improving computer modeling.
  • Scientists are still trying to determine if cloud seeding produces increased snowpack on the ground. The science is still not consistent enough to fully determine the effect, but the science is improving.


  • There are concerns for the environment after seeding a cloud with AgI. Silver is toxic to organisms living in water in high amounts. Shawn Benner, a geochemist, claims that the AgI levels after seeding found in surface water are below 50,000 ppt (the toxic threshold), but if seeding clouds becomes common the silver levels could become a concern.
  • The public is also concerned that silver iodide might make them sick. Science fiction movies and conspiracy theories also mislead the public about the science behind cloud seeding.
  • The public does not understand exactly what happens in cloud seeding and that can create doubt and confusion. One such confusion is that drought can be caused downwind of a cloud seeding event.


The research process began by searching for scientific articles on the effect of cloud seeding. Many articles were readily available. The newest articles indicating an increase in precipitation due to cloud seeding were chosen for the request. The articles found for the lack of implementation all mention that there are some complications with the statistics in the studies and that the public is highly concerned with the health and safety of silver iodide and potential negative effects of cloud seeding.

From Part 03
  • "North American Weather Consultants, incorporated in 1950, specializes in providing Weather Modification, Air Quality Services, Ambient Monitoring, Tracer Studies, Applied Meteorological Studies, and Expert Testimony to clients in the U.S.A. and around the world."
  • "Contacts: Don Griffith, President or Mark Solak, Vice President"
  • "NAWC has conducted weather modification projects and provided consulting services in many countries outside the United States, including Europe, South America, Central America, Asia, and the Middle East."
  • "The Company’s client list includes hydroelectric utilities, government agencies, water districts, universities and private entities"
  • "It was however initially established only as a weather modification company and later expanded into providing other services mentioned above. Weather modification has however always been NAWC's primary specialty"
  • "We are the company with the most experience in Latin America for the realization of projects for planting clouds with terrestrial generators."
  • " Our company has the knowledge and the experience to offer an integral and efficient implementation of this type of programs."
  • "WE ARE SPECIALISTS IN CLOUD SEEDING Extensive experience in the development of cloud seeding programs with the goal of increasing rainfall."
From Part 04
  • "Cloud seeding is a process by which silver iodide is released into the clouds, either from the air or via ground-based generators. In the case of the SNOWIE Project, the silver iodide was released by a second aircraft funded through Idaho Power Co., while the UW King Air took measurements to understand the impact of the silver iodide, French says."
  • "Over 50 countries use cloud seeding for improving the prospects of weather modification. There are several claims regarding the use of various techniques for weather modification for rainfall. Not all methods have been tested or proven scientifically, she pointed out."
  • "The main purpose of AREP in Weather Modification is to promote scientific practices in weather modification research. This is done through the WMO Expert Team on Weather Modification and through organizing the quadriennial scientific conferences on weather modification."
From Part 06
  • "In this study, measurements from ground-based X-band radars, an airborne W-band cloud radar, and in situ cloud physics probes were presented that together provide the strongest evidence yet for the initiation and growth of ice crystals as the result of glaciogenic seeding with AgI, leading to precipitation (snow) on a mountain surface within a specific target region. "
  • "These comprehensive observations provide unambiguous evidence that glaciogenic seeding of a supercooled liquid cloud can enhance natural precipitation growth in a seeded cloud, leading to precipitation that would otherwise not fall within the targeted region. "
  • " However, this study does not directly address cloud seeding effectiveness. Rather, observations such as these are a necessary component for investigations into the efficacy of cloud seeding and, as such, can be utilized in future investigations to quantify cloud seeding impact."
  • "In summary, this case study finds that ground-based glaciogenic seeding enhances snowfall in a shallow, mostly blocked orographic cloud without significant natural precipitation. This study does not address seeding impact in the deeper, precipitating clouds that operational cloud-seeding projects typically target."
  • "This study examines the impact of ground-based glaciogenic seeding on a very shallow (<1 km), largely blocked cloud upstream of the Medicine Bow range in southern Wyoming, observed during the ASCII campaign."
  • "The results of the model ensemble in which the paired seeding effect was estimated for each ensemble member produced a mean precipitation enhancement of 5%, with an inner-quartile range of 3%–7%. These results provide an estimate of the impact of ground-based cloud seeding in the Sierra Madre and Medicine Bow Mountains in Wyoming for the RSE EUs that accounts for key uncertainties in both initial conditions and model physics. As indicated by Ritzman et al. (2015), the RSE cases account for only 30% of the total precipitation, thus the overall seeding impact on annual precipitation over this region is ~1.5%."
  • "AgI particles released from the ground-based generators affect the cloud within the boundary layer below 1 km AGL through nucleating extra ice crystals, converting liquid water into ice, depleting more vapor, and generating more precipitation on the ground."
  • "The seeding effects on the ground precipitation are confined within narrow areas. The relative seeding effect ranges between 5% and 20% for the simulations with different grid spacing."
