The zip file package contains the Instrument Spectral Response Functions (ISRF) for the UV, UVIS, NIR and SWIR detectors, derived from TROPOMI calibration measurements performed in March 2015 at CLS in Liege. Details regarding the file package content, installation as well as the data usage and limitations can be found in the ISRF readme file.

Please note that when unzipped, the entire package contains approximatively 10GB of data. The compressed zip-file is around 8GB to dowload.

In addition to the full IRSF file, a specific file for both bands 1 and 2 using the binning factor of band 1 is provided and is roughly 1GB in size. 

The zip file package contains Pixel Response Functions (PRFs) for all pixel of the UV, UVIS, NIR and SWIR detectors of TROPOMI, derived from star stimulus Earth port geolocation calibration measurements (starEarthGeo) performed from 2015-01-10 15:33:05 until 2015-01-21 02:29:35 at CSL in Liege. For the definition of the Instrument Reference Frame (IRF) and the azimuth and elevation angles defined in this frame, the user is referred to the L01B ATBD (Algorithm Theoretical Basis Document for the TROPOMI L01b Data Processor, Sections 26.1.10 and 26.1.11).

Details regarding the file package contents, installation as well as the data usage and limitations can be found in the PRF readme file.

Please note that when unzipped, the entire package contains approximatively 12GB of data.
