=> Dans le cadre de la préparation de la mission Trishna, une question importante concerne la nécessité de corriger les effets directionnels dans les images, ainsi que la méthode à appliquer. Certains d’entre vous sont sans doute familiers de l’effet dit de « hotspot » dans le domaine réflectif, qui a été bien illustré sur notre blog. […]
=> In the frame of the preparation of the Trishna mission, one important question is : do we have to correct for directional effects, and how should we do it ? Some of you may be familiar with the so-called hotspot effect in the reflective domain, which is well illustrated on our blog. Well in […]
It’s not easy to find a good cartographic representation of the global irrigated land, therefore I made my own map using data from Meier et al. (2018). The raw resolution of the above product is 30 arcsec, i.e. 1 pixel covers about 1 km by 1 km at equator. Here, I aim to represent the […]
As announced in a previous post, the aerosol definition of the new 48r1 release of the CAMS auxiliary data has changed as compared to the former 47r1. At that time, we recommended to disable the use of CAMS data with MAJA before we adapt the code. Meanwhile, we have also tested the actual impact on […]
=> Since a few years, my colleagues from THEIA project and from the data campus at CNES, started designing a new processing and distribution center, named Hysope-II. This centre was initially set up for products related to hydrology. It includes a processing center, a catalog, and a distribution center (hydroweb.next). It was developed in the […]

Ce centre était initialement destiné à produire et distribuer les données spatiales utiles à l’hydrologie. Il inclut un centre […]

The Copernicus Atmospheric Monitoring Service (CAMS) is about to release a new version of its aerosol products on 27 June 2023, referred as 48r1. Their evolution has a direct impact on MAJA, and requires us to adapt the processor. MAJA will not be ready to support 48r1 before the next MAJA release scheduled for September […]
