Theia Snow-Covered Surface Scientific Expertise Centre (SEC) brings together teams from Cesbio, IGE, CNRM (CEN) and Legos. Theia Snow-Covered Surface SEC is dedicated to detect the presence of snow cover, on a continuous, large-scale basis.
A second product provides an annual synthesis of snow cover duration per pixel between September 1 and August 31. It is also distributed on theia.cnes.fr.
Users are the academic sector (research laboratories in hydrology, mountain ecology), mountain water operational management agencies, industry (hydropower producers), agriculture (irrigation companies) and tourism/leisure services (ski resorts, individuals).
