=> 2020 has been a very difficult year for everyone (but it’s over 🙂 ), and the multitemp blog did not make an exception. Our audience has decreased by 13 to 20% depending on the statistics, compared to 2019, which already did not break records. It would be easy to blame the Covid, and I […]

=> Comme presque partout, l’année 2020 a été bien morose au CESBIO ! Même si le CESBIO a été relativement épargné par la maladie, avec un faible nombre de cas bénins jusqu’à présent, quelques uns de nos collègues ont perdu des proches et nous leurs adressons nos plus chaleureuses pensées ! La situation est probablement […]

=> As almost everywhere, 2020 has been a gloomy year at CESBIO ! Even if CESBIO has been relatively spared by the disease, with a low number of mild cases so far, a few of our colleagues lost relatives and we send them our warmest thoughts ! The situation is probably the same for the […]
Copernicus
In the previous post, Olivier advocated for the open data policy in remote sensing. Although Oliver is facing some actual resistance because the Sentinel-HR mission would step on the toes of industrial champions, my feeling is that there is now a large consensus on this issue. The economic and social benefit of the open data […]
Copernicus
As for most users of Copernicus or LANDSAT data I guess, the advantages of free and open remote sensing data are so clear that it’s hard to imagine they could be challenged. However, in the framework of Sentinel-HR phase 0, we prepared arguments in case our requirement for free and open data is questioned. Table […]

Dans le cadre de la préparation de la mission thermique TRISHNA (CNES/ISRO), le Cesbio met en place un dispositif expérimental de suivi de la température de surface dans les Pyrénées. L’objectif principal est de mieux connaitre la plus-value de la température de surface pour caractériser les propriétés internes du manteau neigeux. En particulier, l’assimilation des […]

Copahue is an active volcano in the Andes on the Chile-Argentina border. It erupted in 2016 and a plume of smoke was visible in many Sentinel-2 images during that period. Looking at these pictures I thought it would be fun to use that plume as a giant anemometer to evaluate climate model data. I extracted […]
