Abstract

Commissioning phase in-flight measurements of the MIPAS FT-spectrometer on ENVISAT were analyzed with a dedicated IDL tool regarding radiometric accuracy. This included FT instrument characterization as well as parts of level 1b processing, both independent from the nominal ESA data processing and in-flight characterization. At the present state of analysis MIPAS was found to operate close to the physical sensitivity limit with radiometric errors not exceeding the specifications.
