L. auteur aut IRD Fargant G. auteur aut IRD text journalArticle eng text/pdf born digital access This article presents the MISTIGRI project of a microsatellite developed by the French space agency Centre National d'Etudes Spatiales (CNES) in cooperation with Spain (Image Processing Laboratory of the University of Valencia and Centro para el Desarrollo Tecnologico Industrial (CDTI)). MISTIGRI is a mission that has the originality of combining a high spatial resolution (approximate to 50 m) with a daily revisit in the thermal infrared (TIR). MISTIGRI is an experimental mission devoted to demonstrate the potential of such TIR data for future operational missions. The scientific goals and expected applications of the mission are described: they encompass the monitoring of (i) agricultural areas and related hydrological processes, (ii) urban areas, and (iii) coastal areas and continental waters. Then, the specifications on spatial resolution, revisit frequency, overpass time, and spectral configuration are justified. The strategy of the mission is based on the combination with a network of long-term experimental sites. It will also make possible observing some areas facing rapid climatic change. The choice of the orbit is presented. Finally, we give rapid overviews of both the instrumental concept and the proposed mission architecture. specialized 126 34 9-10 3437-3466 2013 0143-1161 https://www.documentation.ird.fr/hor/fdi:010060357 10.1080/01431161.2012.716921 0143-1161 [F B010060357] https://www.documentation.ird.fr/hor/fdi:010060357 https://www.documentation.ird.fr/intranet/publi/2013/06/010060357.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2013-07-04 2017-08-23 fdi:010060357 fre
