First Sentinel-2 image available

Sentinel-2 is a twin-satellite mission dedicated to monitoring the earth with a high frequency of every 5 days at the equator and a large swath of 290 km. The satellite carries a sensor tuned to record electromagnetic radiation at key wavelengths for vegetation, in the so called red-edge region. An enhanced 10m spatial resolution at certain bands will provide the opportunity to identify objects that were appearing fuzzy in long established satellite missions such as Landsat. For instance, a smallholder farm covering a single hectare would appear as a handful of pixels in a Landsat image and acquired biweekly in the best case; Sentinel-2 would provide a considerable richer, both temporally and spatially, information on a smallholder farm at a zero cost and under an open-access policy. All in all, the combination of frequent revisiting, the high spatial resolution and the wide swath are leveraging new opportunities and applications in earth monitoring, such as STARS objective in studying small farming systems.
