Retrieved ozone profiles are used to monitor the evolution of stratospheric and tropospheric ozone. Such monitoring is important as the ozone layer protects life on Earth against harmful UV radiation. The ozone layer is recovering from depletion due to manmade Chlorofluorocarbons (CFCs). Tropospheric ozone is toxic and it plays an important role in tropospheric chemistry. Also, ozone is a greenhouse gas and is therefore also relevant for climate change.

The main parameters in the file are the retrieved ozone profile at 33 levels and the retrieved sub-columns of ozone in 6 layers. In addition, the total ozone column and tropospheric ozone columns are provided. For the ozone profile, the precision and smoothing errors, the a-priori profile and the averaging kernel are also provided.

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.
