The Multi Band Auxiliary DEM Data product provides essential surface altitude and classification information to support accurate atmospheric retrievals. This dataset incorporates high-resolution data from the 90-meter Copernicus Digital Elevation Model (DEM) to characterize the surface beneath each TROPOMI pixel.

Elements in the filename separated by underscores after the initial "S5P":
* processing type: off-line (OFFL), reprocessing of off-line (RPRO)
* product identifier [10 char.]
* start date and time of granule
* end date and time of granule
* orbit number [5 char.]
* collection number [2 char.]
* version number [6 char.]
* production date and time
In case of OFFL and RPRO granules are full orbits; near-real time (NRTI) data is not stored.
