Based oo the systematical analysis of the ioherent defect of DMSP/OLS non-radiaoce-calibrnted nighttime light intensity data, a systematic calibration procedure for DMSP/OLS nighttime light images of Chine was proposed. Then the calibration model has been constructed based on ArcGIS Desktop platform. The result shows that it has effectively eliminated the unstable lit pixels and the abnormal fluctuations appeared in DN values of the DMSP/OLS time series nighttime light images, and greatly enhanced the comparability and continuity of the data series. It demonstrates that the model has achieved preferable calibration results both in quantity scale and spatial scale.
