Abstract

The Multi-Azimuth UV Imager (MAVI) is a totally new passive sensor onboard. MAVI gives real time spectral scattering information from multi-direction of ±(70°–73°) limb and ±5° nadir field. Introduction of MAVI has been stated in detail. Based on the design of MAVI, the wavelength and radiance calibration have been respectively and specifically described, which include the approach, the measured setup and the calibration results. The method, first segmenting and then combining fields, has been proposed and adopted in the whole radiometric calibration. Analysis shows that the absolutely combined standard uncertainties of three bands are respectively 5.4%, 5.1%, 4.4%.
