Sentinel :ESA is developing a series of next-generation Earth observation missions, on behalf of the joint ESA/European Commission initiative GMES (Global Monitoring for Environment and Security). Sentinel/SLSTR-A :SLSTR instrument on board Sentinel-3A. Following ENVISAT's AATSR instrument, the SLSTR instrument is a conical scanning imaging radiometer employing the along track scanning dual view technique.id:Sentinel/SLSTR-A.a |
