TROPOMI Level 2 Ozone (O3) Profile in NRT - Sentinel-5PThe O3 profile product provides vertical information of the ozone concentrations in
three different ways:
• As a number density profile at 33 pressure levels;
• As 6 sub-columns with a vertical sampling of 6 km up to an altitude of 24 km and
lower sampling above;
• As the total column and tropospheric column.
The UV Earth radiance spectra contain approximately 6 independent pieces of information
on the vertical profile of ozone. The retrieval is based on optimal estimation, which
combines the information from the measured spectra with a priori information. In addition
to the profile information listed above, the O3 profile product contains additional
information on the retrieval result, including the noise and smoothing errors, the
error covariance matrix and the averaging kernel. Advanced users are encouraged to
use the averaging kernel when comparing to or combining the ozone profile with other
data sets.
The O3 profile data product is derived from the TROPOMI Band 1 and 2. The spatial
sampling is 28 × 28 km2 in nadir and contains 77 pixels in the across flight direction.
This sampling is achieved by combining ground pixel on-ground.
