Over 25 years of experience in cloud seeding operations and technological development.
Operational programs, technological evolution, and regional implementation.
Mettech and its founding team have over 25 years of continuous experience in the design, implementation, and operation of Ground-Based Cloud Seeding Programs.
Since 2000, the team has participated in and led multiple precipitation enhancement initiatives, progressively evolving from field operations to system design, automation, and full program implementation.
To date, nine Cloud Seeding Programs have been developed and operated in Latin America and the Caribbean.
Over 25 years of continuous experience in the design, implementation, and operation of weather modification programs.

Headquarters in Mexico and Argentina. Launch of Technology Transfer programs.
Multisectoral Strategic Alliance: This program represents a milestone in collaborative water management, uniting the most relevant actors in the region to ensure water supply.
Contracting Parties: El Teniente Division of Codelco Chile, Pacific Hydro S.A., and the Cachapoal River Supervisory Board (1st section).
Results: 32% increase in the Cachapoal River flow.
Innovative program in tropical climates carried out year-round with a deployment of 25 installed Generators.
Contracting Parties: Civil Aviation Institute of Cuba and Ministry of Science, Technology, and Environment of Cuba.
Results: 14 to 17% increase in precipitation. – Analysis conducted by the Meteorological Institute of Cuba.
Collaborative program with the Cuban project where a network of 12 Generators was installed in two important basins of the country.
Contracting Parties: National Institute of Meteorology and Hydrology (INAMEH), Venezuela, and Ministry of Science, Technology, and Environment of Venezuela.
Results Achieved: 10 to 12% increase in precipitation. Analysis conducted by the National Institute of Meteorology and Hydrology (INAMEH).
Program initiated due to the severe water deficit suffered by the region, contracted by private entities with state contributions.
Contracting Parties: Private contributions from companies and farmers in the region.
Results Achieved: 18% increase in precipitation. Based on statistical analyses performed by our company with rainfall data from the stations of the General Water Directorate of Chile.
Program designed for snow accumulation in the upper part of the Aconcagua River Basin. Carried out since 2012, it started as a regional project and is now focused specifically on this basin.
Contracting Parties: Aconcagua River Supervisory Board First Section, Codelco Andina, Esval.
Results Achieved: 10% increase in precipitation. Analysis conducted by the National Irrigation Commission of Chile (CNR) 2013.
Design Study for a network of Silver Iodide Ground Generators, as well as the implementation of an aircraft for Silver Iodide Cloud Seeding, both aerial and ground-based, to increase precipitation for the benefit of the State of Chihuahua, Mexico.
Contracting Parties: Secretariat of Rural Development, State of Chihuahua, Mexico.
Program designed for snow accumulation in the Elqui River Basin during the winter season, operations started at the end of the 2024 season.
Contracting Parties: Elqui River Supervisory Board.
Results Achieved: The program is still too new for a concrete measurement of results.
Study for a Precipitation Enhancement Program through Silver Iodide Cloud Seeding, to mitigate the effects of drought in the Department of Tacna, Peru.
Contracting Parties: Special Project Tacna (PET). Tacna, Peru.
Program focused on summer season rainfall, aiming to reinforce the water system of the Chaco Province, Argentina. Activities started in December 2025.
Contracting Parties: Agricultural companies in the province.
Results Achieved: Due to its short application period, outcome studies have not yet been conducted; projected results are similar to those in Cuba, with an 18% increase.
Mettech has developed three generations of Silver Iodide Ground-Based Generators, progressively incorporating:
Self-managed systems that optimize consumable usage and seeding precision without constant manual intervention.
Full real-time control of each unit, allowing for preventive diagnostics and immediate operational adjustments.
Advanced integration of cellular and satellite communications for uninterrupted operation in complex geographical environments.
Optimized designs to facilitate field maintenance and ensure operational continuity under extreme weather conditions.
This continuous evolution reflects our design philosophy: robust technology born from real operational experience. Each generation is the result of thousands of hours of operation in the most demanding conditions in Latin America.
