Sentinel-3 OLCI Tandem 2018
What was the purpose of OLCI Tandem
In Summer 2018, during the Sentinel-3A / Sentinel-3B tandem phase, thanks to a joint effort of the S-3 team and the EE-8 Fluorescence Explorer (FLEX) team, OLCI (on the B unit) was operated for selected orbits in a special sequence acquiring 45 individual bands, and maximising the spectral resolution in the oxygen absorption bands. In this way, it was possible to acquire a set of real measurements to test at first the future FLEX Level-2A processing (i.e., geometric, radiometric and spectral co-registration), and the Level-2B processing (i.e., atmospheric characterisation using OLCI A and subsequent atmospheric correction for OLCI B in different spectral channels).
What was the outcome of OLCI Tandem
In total, 24 acquisitions were taken in this mode during the time window 14 June to 14 August 2018. Each acquisition covered more than 1500 km along track, and the pattern was optimised in order to collect data over several ground sites instrumented with continuously operating systems and regularly overpassed with airborne systems within the ATMO-FLEX and FLEXSense ESA projects.
