Sentinel-5 Precursor Level 2 Ozone Profile

Sentinel-5 Precursor Level 2 Ozone Profile


get data


The TROPOMI instrument onboard Sentinel-5 Precursor is a nadir-viewing, imaging spectrometer covering wavelength bands between the ultraviolet and the shortwave infrared. The instrument uses passive remote sensing techniques to attain its objective by measuring, at the Top Of Atmosphere (TOA), the solar radiation reflected by and radiated from the earth.

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.
