Ready to use Copernicus Sentinel 3 data

Anu Reinart | 28.06.2016

Sentinel 3 satellite that was built by European Space Agency for the EC programme Copernicus is already delivering first images, even satellite is still in commissioning phase. Water remote sensing group in Tartu Observatory has been participating in Sentinel 3 Validation Team to prepare the use of new data.

One large goal for TO team is to collect ground data for the validation of satellite measurements. In Estonia the test site is Lake Peipsi, but our cloudy sky and windy weather make this task very challenging. However the first good data are already here, as can be seen on the image from 14 June 2016 when also field campaign on the Lake Peipsi took place.

„We have been waiting for that image since we joined the Sentinel 3 Validation Team, but did not expect, that we are so lucky already in the early stage of the mission”, said Krista Alikas, researcher in Tartu Observatory, who defended her PhD thesis just few weeks ago. She have developed several new algorithms to detect from satellites water quality parameters that can be used in reporting for EC Water Framework directive. First results and analyses from new satellite will be presented to ESA, EUMETSAT and members of Sentinel 3 validation Team during meeting in ESA/ESRIN at 29-30 June 2016.
