The climate is the fundamental factor that determines the Sahelian natural environments. Mauritania is one of the Sahelian countries most affected by droughts that have followed since 1970. This succession of drought has weakened vegetation and caused soil depletion. This study characterizes the climate trends of Diawling National Park (PND) and its peripheral area over the period 2000-2013. It seeks to highlight the importance of space data for climate characterization in the Sahel region, using maximum and minimum temperatures derived from MODIS imagery (with a resolution of 0.05 ° or 5 km) and rainfall data derived from TRMM (with a spatial resolution of 0.25 ° or 25 km). These two parameters were compared with the vegetation index (NDVI, derived from MODIS images with a temporal resolution of 16 days and a spatial resolution of 250m). The results from the spatial data were validated referring to Rosso meteorological station.
