Neural network scheme for the retrieval of total ozone from Global Ozone Monitoring Experiment data.
A novel approach to retrieving total ozone columns from the ERS2 GOME (Global Ozone Monitoring Experiment) spectral data has been developed. With selected GOME wavelength regions, from clear and cloudy pixels alike plus orbital and instrument data as input, a feed-forward neural network was trained to determine total ozone in a one-step inverse retrieval procedure. To achieve this training, gro...
متن کاملOzone profile retrieval from Global Ozone Monitoring Experiment (GOME) data using a neural network approach (Neural Network Ozone Retrieval System (NNORSY))
[1] The inverse radiative transfer equation to retrieve atmospheric ozone distribution from the UV-visible satellite spectrometer Global Ozone Monitoring Experiment (GOME) has been modeled by means of a feed forward neural network. This Neural Network Ozone Retrieval System (NNORSY) was trained exclusively on a data set of GOME radiances collocated with ozone measurements from ozonesondes, Halo...
متن کاملImpact of using different ozone cross sections on ozone profile retrievals from Global Ozone Monitoring Experiment (GOME) ultraviolet measurements
We investigate the effect of using three different cross section data sets on ozone profile retrievals from Global Ozone Monitoring Experiment (GOME) ultraviolet measurements (289–307 nm, 326–337 nm). These include Bass-Paur, Brion, and GOME flight model cross sections (references below). Using different cross sections can significantly affect the retrievals, by up to 12 Dobson Units (DU, 1 DU=...
متن کاملAn Eight-year Record of Ozone Profiles and Tropospheric Column Ozone from Global Ozone Monitoring Experiment (gome)
This paper presents an eight-year record (July 1995June 2003) of ozone profiles and tropospheric column ozone (TCO) retrieved from GOME ultraviolet radiance spectra using the optimal estimation technique, including detailed treatments of wavelength and radiometric calibrations and forward radiative transfer modeling. The agreement with Stratospheric Aerosol and Gas Experiment (SAGE) data is usu...
متن کاملGlyoxal retrieval from the Ozone Monitoring Instrument
We present an algorithm for the retrieval of glyoxal from backscattered solar radiation, and apply it to spectra measured by the Ozone Monitoring Instrument (OMI). The algorithm is based on direct spectrum fitting, and adopts a two-step fitting routine to account for liquid water absorption. Previous studies have shown that glyoxal retrieval algorithms are highly sensitive to the position of th...
