| Zusammenfassung |
| Ural Atmospheric Fourier Station (UAFS) is arranged in Kourovka Astronomical
Observatory of Ural State University. The UAFS situated at 57.038N and 59.545E in forest
area and operated since July of 2009. The UAFS is equipped with Bruker Optics IFS125M
with spectral resolution of 0.0035cm-1 and solar tracker A547N. Set of passed through the
atmosphere solar spectra from the range of 4000-11000cm-1 with resolution of 0.05 -
0.0035cm-1 were recorded during clear sky conditions using the FTIR from July 2009.
Based on independent data of AERONET spectrometer in Kourovka, the spectra
corresponding to weak aerosol atmosphere have been selected for further analysis
with GFIT. The GFIT outputs for column mean concentration of CO2, CH4, CO,
N2O, H2O and other trace gases are obtained. Original method for determination
of HDO to H2O ratio in the atmosphere from the FTIR spectrum is suggested.
Validation of TANSO-FTS/GOSAT CH4, CO2 and HDO-H2O retrievals are
discussed.
