Assuming that the differences between the instruments can be represented by an incidence-angle-dependent bias, this paper presents and discusses four methods, providing an estimate of that bias and of its standard deviation. Model-based methods performed more accurately than a direct comparison of sigma(0). The latter provides a systematic larger positive bias. The methodology is applied to ERS-1 and ERS-2 data acquired during the tandem mission in 1996. The same methodology is applied to ERS-2 and Advanced Scatterometer (ASCAT) data acquired in December 2008. Generally, the bias between the ERS-1 and ERS-2 scatterometers is smaller than 0.2 dB over most incidence angles, and the four methods provide relatively consistent results. The bias between ERS-2 and ASCAT is slightly higher, reaching 0.4 dB at certain incidence angles. These results suggest that these scatterometers need to be intercalibrated to achieve a consistent backscatter data.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"C-band satellite scatterometer intercalibration","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-06 01:33:14.531132","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"ASCAT; calibration; ERS; radar remote sensing; scatterometer; sea ice;sea surface; spaceborne radar","OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2020-06-25","DateCreate":"2016-05-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000315725900037","VABBcode":null,"OpenAcc":0,"DOI":"10.1109/TGRS.2012.2217381"},"refs":null,"anarec":{"AnaID":257359,"PubliDate":2013,"Pagination":"1478-1491","XtraPublOfAnaID":null,"ISBN":null,"Volume":"51","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43132,"SerRR":"IEEE transactions on geoscience and remote sensing.
