The TROPOMI instrument, single payload onboard S5P, retrieves operationally the most important quantities for cloud correction of satellite trace gas retrievals: cloud fraction, cloud optical thickness (albedo), and cloud-top pressure (height). Cloud parameters from TROPOMI are not only used for enhancing the accuracy of trace gas retrievals, but also to extend the satellite data record of cloud information derived from oxygen A-band measurements initiated with GOME.

Elements in the filename separated by underscores after the initial "S5P":
* processing type: near-real time (NRTI), 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, for NRTI granules are 5-minute chunks of orbits.
