Zusammenfassung |
The ESA project „SEOM-Improved Atmospheric Spectroscopy Databases (IAS)“ will
improve the spectroscopic database for retrieval of the data products CO, CH4, O3 and SO2
column amounts measured by the TROPOMI instrument (TROPOspheric Monitoring
Instrument) aboard the Sentinel-5 Precursor. The project was launched in February 2014 with
3 years duration extended to 4 years recently. The spectroscopy of CO, CH4 and O3 in the
2.3 μm region is covered first while UV measurements of SO2 and UV/FIR/IR
measurements of ozone will be carried out later.
Measurements were mainly taken with a high resolution Fourier Transform spectrometer
combined with a coolable multi reflection cell. Cavity ring down measurements served for
validation. The analysis has been completed. A clear improvement can be seen when using
the new data for CH4, H2O and CO retrieval from ground-based high resolution solar
occultation measurements obtained with instrumentation in the TCCON and NDACC
network. |
