Relationship between DMSP/OLS nighttime light and CO2 emission from electric power plant

In this study, we estimated the CO 2 emission by fossil fuel consumption from electric power plant using DMSP stable light image for 1999 after correction for saturation effect. Digital number (DNs) of the stable light image in center of city areas are saturated for the strong nighttime intensity and characteristic of the OLS satellite sensor. To estimate the CO 2 emission using stable light image, saturation light correction method was developed by using DMSP radiance calibration image, which has not included saturation pixel in city areas. Then, regression analysis was performed with cumulative DNs of the corrected stable light image, electric power consumption, electric power generation and CO 2 emission by fossil fuel consumption from electric power plant each other. Results indicated that there are good relationship (R 2 2 emission from electric power plant using corrected stable light image.
