## Editorial
Sentinel-5P TROPOMI Level-2 Total Ozone Column is an open Copernicus ozone data product distributed by ESA for total column ozone, ozone-layer monitoring, and atmospheric composition workflows [^s5p-o3-total]. The product is available through Copernicus Sentinel access channels and NASA GES DISC, with free and open access under the Copernicus Sentinel open access model [^s5p-o3-total]. Product files are NetCDF-CF and include total ozone, ozone temperature, and error information, which supports screening, trend analysis, and assimilation workflows that need retrieval uncertainty alongside the ozone column field [^s5p-o3-total]. As a Sentinel-5P TROPOMI Level-2 geophysical product, it fits users who need orbital, instrument-level ozone retrievals rather than gridded Level-3 maps [^s5p-products].
