Large-scale validation of SCIAMACHY reflectance in the ultraviolet
[摘要] In this paper we present an extensive validation of calibrated SCIAMACHY nadir reflectancein the UV (240-400 nm) by comparison with spectra calculated with a fast radiativetransfer model. We use operationally delivered near-real-time level 1 data, processed withstandard calibration tools.A total of 9 months of data has been analysed. This is the first reflectance validation studyincorporating such a large amount of data. It is shown that this method is avaluable tool for spotting spatial and temporal anomalies. We conclude that SCIAMACHYreflectance data in this wavelength range are stable over the investigated period.In addition, we show an example of an anomaly in the data due to an error in theprocessing chain that could be detected by our comparison.This validation method could be extremely useful too for validation of other satellitespectrometers, such as OMI and GOME-2.
