Abstract
A new technique for retrieving the total ozone column (TOC) by interpreting satellite measurements of outgoing thermal radiation of the Earth (IKFS-2 spectrometer, Russian satellite Meteor-M No. 2) is suggested and analyzed. The technique is based on an inverse operator which is constructed using ground-based standard observations (Dobson and Brewer spectrophotometers) and satellite measurements of TOC along with multilinear regression. The technique is analyzed with the standard ground-based Dobson measurements of TOC at Voeikov station, Leningrad oblast (Voeikov Main Geophysical Observatory).
The analysis shows that multilinear regression between the ground-based and satellite data allows approximating TOC in Voeikovo for 2015–2020 with an error of 2.8% and a correlation coefficient (CC) of 0.97. The TOC time series retrieved from the solution of the inverse problem by the regression method has an error of 3.1% and a CC of 0.97. The technique suggested can be used for different regions of with TOC retrieved from ozone measurements at World Meteorological Organization (WMO) stations.
