What Cimel Electronique does

Cimel Electronique is a French manufacturer of meteorological and atmospheric observation systems headquartered in Paris, operating for more than 50 years as the industrial link between the scientific research community and operational atmospheric monitoring. The company designs, manufactures, and sells ground-based and (as of 2026) spaceborne remote sensing instruments — notably the CE318-T Sun/Sky/Lunar Photometer (the exclusive standard of NASA's AERONET network), the CE376 micro-LiDAR, the CE710 Raman LiDAR, and the CE312 thermal infrared radiometer — alongside integrated solutions such as the AAMS (Automatic Aerosol Monitoring Solution) and proprietary data processing software (iAAMS, AUSTRAL).

The technical platform combines field-proven, autonomous hardware engineered for harsh environments with advanced retrieval algorithms (notably GRASP integration) to deliver standardized, WMO-traceable atmospheric observations for aerosols, clouds, water vapor, and thermal radiation. Cimel instruments are deployed across 600+ permanent stations in 80+ countries and are integrated into every major global atmospheric observation network (AERONET, ACTRIS, LALINET, AEROCAN, RIMA, ATMOSUD, EMME-CARE).

The business model is direct enterprise sales of high-value scientific instruments and integrated systems to space agencies (NASA, ESA, CNES, NOAA, JAXA), national meteorological services (Météo-France, AEMET, BMKG, ASECNA), research institutions (CNRS/LOA, LATMOS, University of Lille, TROPOS, Cyprus Institute), and commercial customers (Boeing, ICAO, EDF, ISAGRI). Revenue is generated through hardware sales, calibration services, firmware updates, and technical support tied to the installed base, supplemented by an exclusive Italian channel partner (XEarPro Srl) and bilateral cooperation/government procurement missions.
