ESA Precursors for Aerosols and Ozone Climate Change Initiative (Precursors_cci): daily and monthly L3 SO2 from OMI, version 1.0

Le résumé fourni par la source

The Sulfur Dioxide (SO2) Climate Data Record (CDR) product is a Level 3 SO2 product developed by using satellite data from the Ozone Monitoring Instrument (OMI) (on Aura) as part of the ESA Climate Change Initiative (CCI) Precursors for Aerosols and Ozone project. This dataset provides gridded SO2 column densities of monthly 0.125°x0.125° and daily 0.25°x0.25° resolution grids from October 2004 to December 2022. The L3 product is based on the Level 2 SO2 product created for the Precursors_cci project. Compared to the operational OMI product, the SO2 slant columns are computed using the COBRA scheme, the air mass factors have been processed using the CAMS Reanalysis Model for the a priori vertical profiles. In addition to the main product results, such as SO2 slant column, vertical column and air mass factor, the Level 3 data files contain several additional parameters and diagnostic information such as uncertainties, a priori profiles and averaging kernels. Data are available in NetCDF format. The European Space Agency (ESA) Precursors for Aerosol and Ozone Climate Change Initiative (Precursors CCI) project is part of ESA's Climate Change Initiative (CCI) to produce long term datasets of Essential Climate Variables derived from global satellite data (https://climate.esa.int/en/projects/precursors-for-aerosols-and-ozone/).
