S5P support for QAO4EO Ruhr 2019 / 2020 campaigns
Introduction Data References Links Contact
Introduction:
The S5PVAL-DE-Ruhr campaign, planned for summer 2020, is an ESA funded collaboration between IUP-Bremen,
Free University of Berlin,
Max-Planck-Institute for Chemistry Mainz and
BIRA, aiming at the validation of the Sentinel-5p nitrogen dioxide product.
The campaign takes place in Germany’s most populous federal state North Rhine Westphalia and focusses on three target sites for airborne
measurements covering regions with industrial (point source) as well as urban (diffuse) emissions or a mixture of both. These sites
are located in urban agglomerations of Duisburg (51.44°N, 6.76°E), Cologne (50.94°N, 6.97°E) as well as the Rhenish lignite mining
district (50.92°N, 6.51°E), comprising three large power plants in Germany.
The airborne imaging DOAS instrument AirMAP, developed at IUP-Bremen, will map the horizontal distribution of nitrogen dioxide (NO2)
in an area of about 30x30 km2 within a time window of about three hours at a spatial resolution better than 100 m. The flights will
be optimized to coincide with the overpasses of the Sentinel-5p satellite (S5p), so that the gapless-maps derived from AirMAP can be
used for direct comparison to the S5p product. The airborne measurements will be supported by ground-based stationary and mobile DOAS
measurements performed by BIRA, MPIC and IUP-Bremen.
In addition, direct Sun measurements will be performed by two Pandora instruments provided by NASA
which are deployed in Cologne and on the premises of the Jülich research centre close to
the power plants, which also hosts an AERONET station.
Data:
The IUP-Bremen provides near realtime tropospheric NO2 columns from the TROPOMI instrument on Sentinel-5 Precursor. The data are from the operational NO2 NRT data stream. All plots are produced automatically and without explicit quality control. Usually, the plots should be available 2 hours after measurement. If you experience any problems, please contact Andreas Richter.
