Snow cover duration from 01 Sep 2017 to 31 Aug 2018 in the Alps and Pyrenees

=> We are thinking to distribute a new product that would provide the snow cover duration in the Alps and the Pyrenees over a hydrological year (snow persistence map). Here is a preview of a « beta » version that is only 100 m resolution for now. 

 A few words on the method (see also here): this map is generated after a linear interpolation at the daily time step of every available Theia snow product. Here we have selected 26 Sentinel-2 tiles, which represents 3189 snow maps for the study period, that is 96 billion pixels to process. With the accumulation of Sentinel-2 data it becomes possible to look at interannual variability. Here is for example a visual comparison of the snow cover duration calculated from January to May for three years in the Pyrenees (31TCH):

Snow cover duration 31TCH

 We can see longer snow durations for the year 2018, which was an exceptional year!

Near real time snow cover maps in the Copernicus Browser!

Copernicus provides near real time snow cover maps at 20 m resolution (fractional snow cover, code name: FSC OG). These products have been recently reprocessed and are now available through the Copernicus Data Space Ecosystem (CDSE) API and visualization tool, the Copernicus Browser! The latter is very useful to explore the data, for example if […]

Suivi du manteau neigeux dans les parcs naturels des Alpes franco-italiennes

Dans les Alpes, le manteau neigeux est un stock d’eau saisonnier naturel dont dépendent la faune, la flore et les humains pour de multiples usages (refuges, bétail, etc.). Dans le cadre du projet ACLIMO financé par le programme européen Interreg ALCOTRA, le Cesbio a été sollicité pour mettre en oeuvre un outil d’estimation de l’équivalent […]

The missing link to valorize CESBIO’s applicative research works

=>  My colleagues at CESBIO are extremely creative! Over the past ten years, they have developed a wide range of new products and methods for extracting information from Copernicus data. They don’t just develop and validate the method on a few sites; they continue their work until they have produced data for the whole of […]
