TROPOMI seasonal mean upper tropospheric NO2


TROPOMI annual mean upper tropospheric (UT) NO2 obtained with FRESCO-S (top) and ROCINN-CAL (bottom) cloud products

Data Description:
TROPOMI UT NO2 seasonal means for June 2019 to May 2020 obtained at 1° x 1° using cloud-slicing. Two data products are available, obtained with distinct cloud products. These are labelled FRESCO-S and ROCINN-CAL. Details of the cloud-slicing methodology, the difference between the 2 products and the causes for these differences, and comparison to the existing OMI cloud-sliced UT NO2 product are described in the publication detailed below.
