English abstract:
Scatterometer derived products have become an important input dataset for climate change research. For this reason accurate radiometric calibration of scatterometer is a prime requirement from the scientific community to enable them to establish a long-term consistent scatterometer dataset. The calibration method that we introduce here is a stepwise relative calibration approach using extended area Land-Targets. Intra-calibration of a scatterometer mission will account for instrument related drifts, while inter-calibration is performed to identify possible difference of various scatterometer missions. Similarities in instrument design of ERS-2 AMI and MetOp-A ASCAT allow the merging of these datasets, with the proposed stepwise calibration approach, and result in global backscatter observations spanning over 20 years.
