Abstract

In our previons study radiometric cross-calibration for CCD camera using MODIS data

and they gave the radiometric coefficients and offsets were given.However

the calibration precision of those calibration coefficients is not so good

since the BRDF of the calibration sites was not considered.What’s more

the calibration coefficients for time series of CCD data are limited because calibrations were performed for the pairs of images of which the viewing zeniths of the MODIS are smaller than 30°.The effort of the article is to enhance the calibration precision of calibration coefficients for CCD data by considering the BRDF of the calibration sites.And more complete calibration coefficients for time series of CCD data are intended to be provided.
