Total ozone product from OLCI / S-3_Antarctica _S3

The total ozone column (TOC) is derived by the team using the top-of-atmosphere measurements of the Ocean and Land Colour Instrument (OLCI) on board Sentinel-3 A/B. OLCI operates in the spectral range 400-1020nm. The TOC has been derived using Sentinel-3 OLCI Level 1 product at full resolution (300m). This is the first attempt to derive the total ozone column at such high spatial resolution. The team also created a cloud mask, a snow mask and an atmospheric correction procedure.The OLCI ozone processor is planned to be delivered to ESA in April 2021 providing the ozone research community with a total ozone product from OLCI / S-3 in Antarctica and also over other snow-covered areas including Greenland.
