Popis:	Since the first images from the sensors onboard CBERS‐2 (China–Brazil Earth Resources Satellite) were made available by the National Institute for Space Research (INPE), users have requested information about the conversion of image digital numbers into physical data (radiance or reflectance). This Letter describes the main steps that were carried out to calculate the in‐flight absolute calibration coefficients for CBERS‐2 Infrared Multispectral Scanner (IRMSS) level 2 (radiometric and geometric correction) images considering the reflectance‐based method. Remarks about the preliminary evaluation of the application of these coefficients are also presented.
