Tuesday 23th of June 2015, at 3:52 CET the ESA earth observation satellite Sentinel-2A was successfully launched.

Sentinel-2 records images in 13 spectral channels in the visible, near infrared and short wave infrared, with a spatial resolution of 10 m. In 2016 the identical Sentinel-2B will be launched. The short revisiting time of the two Sentinel-2 satellites together opens up great opportunities: each point on earth will be recorded every five days. This is especially interesting for the monitoring of fast changing vegetation through the year (phenology), which is a relevant parameter for the urban energy budget. And, with recordings every week, the chances of cloud-free EO-images over Europe are increased.

The high spatial resolution will enable the mapping of a large variety of surface characteristics, even in heterogeneous areas of cities. In URBANFLUXES this will be used. It will allow, together with information from Sentinel satellites, to derive the current state of the cities. The resulting maps will be the input for urban energy budget calculations.
