Comparison of total ozone column content given by satellite and retrieved from ground-based remote sensing

Abstract

The purpose of the study is to determine the total ozone column content from spectral irradiances measured at the surface and compare these values with the corresponding obtained from satellite remote sensing. The spectral irradiances measured at the surface are acquired by the Multi-Filter Rotating Shadow Band Radiometer YES MFR-7, installed in the Observatory of the Geophysical Centre of Évora and the satellite remote sensing values are obtained from the Ozone Monitoring Instrument (OMI), onboard AURA satellite, once a day.
