COMPARISON OF SCIAMACHY OTHER PRODUCTS (AOIDs 126, 174, 427)

摘要

Comparisons have been performed between the SCIAMACHY CO, CH4 and H2O columns and ground-basedrnmeasurements performed at different stations. SCIAMACHY CO, CH4 and H2O columns show unrealistic values,rnorders of magnitude too high, negative values, large spread and constant values at high solar zenith angles. These errorsrnare largely caused by calibration problems. The comparisons with ground-based measurements do not provide muchrnadditional information, given the current status the SCIAMACHY CO, CH4 and H2O products.
