Spectral Response Function Data
In the frame of pre-launch activities for Sentinel-3's OLCI-A instrument, a first version of the instrument Spectral Response Functions (SRFs) based on on-ground characterisation measurements was derived. The spectral characterisation information is provided in the following three files with three different levels of detail:
The way the data are generated and the underlying theoretical model are described in this Technical Note.
Note: Further calibration and validation activities are planned in the frame of the Sentinel-3A Commissioning Phase. These activities should allow verifying the in-flight performance of the instrument. It is in particular foreseen to review the pre-launch instrument spectral characterisation measurements from which the present SRFs are derived. If deemed necessary, an update of the SRFs might thus be provided at the In-Orbit Commissioning Review (IOCR), 5 months after the launch. Moreover, the spectral characteristics of OLCI-A will be monitored through the entire mission duration and this might again lead to updates of the instrument SRFs at a later stage in the mission lifetime.
