Soil moisture maps at a high resolution over Occitania region

Applications In English Sentinel-1 Sentinel-2 THEIA

Olivier Hagolle, 30 septembre 2017

=> Translated from Theia website.The Theia forges just released a new product based on Sentinel-1 and 2 data. Le « High resolution soil moisture » Scientific Expertise Center, driven by Nicolas Baghdadi, from Tetis lab in Montpellier and Mehrez Zribi from CESBIO, distributes Soil Moisture maps from the French Occitania region at 20 m resolution, produced every sixth day from September 2016 to May 2017.
The product uses time series of the Copernicus S1 and S2 satellites.  The inversion method is based on neural networks. It is applied only on crop lands (with or without vegetation), which are extracted from the Sentinel-2 2016 land cover map of France produced by Theia (Jordi Inglada et al., CESBIO).
These maps were developed and produced thanks to support from IRSTEA (UMR Tetis) and CNES (Tosca Project). The first data are available following this link. It is of course planned to turn to an operational production on the whole France, but as always, going from prototype to operational processor will take some time.

Three Sentinel-2 satellites instead of two: impact on the retrieval of the snow disappearance date

Due to the success of Olivier’s petition, ESA kept Sentinel-2A operational after the launch of Sentinel-2C. Having three operational satellites instead of two increases the revisit, which should improve the quality of the derived products, and therefore the reliability of operational services based on Sentinel-2 data. One of this service is the Copernicus’ High Resolution […]

Autumn snow drought on Mount Damavand

« We are currently experiencing the driest autumn the country has experienced in 50 years » said Iran’s meteorological organisation. Near Tehran, Mount Damavand, the highest peak in Iran (5609 m) was reported to be « unusually bare of snow ». I checked this statement using my MODIS snow cover data processing algorithm implemented in Google Earth Engine (Gascoin […]
