Six Years of IKFS-2 Global Ozone Total Column Measurements

Atmospheric ozone plays an important role in the biosphere’s absorbing of dangerous solar UV radiation and its contributions to Earth’s climate. Nowadays, variations are widely monitored by different local remote sensing methods. Satellite methods can provide data on global distribution anomalies. In contrast measurement techniques based measurements, Fourier-transform infrared (FTIR) satellite measurements thermal information, regardless illumination. The total columns (TOCs) measured IKFS-2 spectrometer aboard “Meteor M N2” for period 2015 2020 is presented. retrieval algorithm uses artificial neural network (ANN) TOCs Aura OMI instrument method principal components representing spectral measurements. Latitudinal seasonal dependencies ANN training errors analyzed considered as a first approximation TOC errors. derived compared independent ground-based data. average differences between up 2% (IKFS-2 usually slightly underestimates other data), standard deviations (SDDs) vary from 2 4%. At same time, both analysis comparison results with demonstrate increase discrepancies towards poles. spring–winter period, SDDs reach 8% Southern 6% Northern Hemisphere. technique presented be used process data, result, it information 2015–2020, illumination presence clouds.
