| Zusammenfassung |
| The practical usefulness of a desktop optical spectrum analyzer (OSA) for
measuring atmospheric CO2 and CH4 column densities at surface
sites was examined in two separate measurement campaigns. The first
comparison involved operating the OSA in parallel with a high resolution
Fourier transform spectroscopy (FTS) situated at the University of
Wollongong in Australia. Scale factors for the OSA were assigned for the
column average volume mixing ratios of xCO2 and xCH4 by comparing
with the well-studied FTS. The second method is a calibration against
aircraft CO2 profiles in situ over Tsukuba in Japan obtained during a
GOSAT validation campaign carried out from 28 January to 7 February 2011.
The xCO2 values in the campaign, deduced by use of a derived OSA scale
factor, were in excellent agreement with the integrated aircraft profiles. |
