Modeling the spatiotemporal dynamics of electric power consumption in Mainland China using saturation-corrected DMSP/OLS nighttime stable light data

摘要: Obtaining timely and accurate data on the spatiotemporal dynamics of electric power consumption (EPC) is crucial for effective utilization in China. The Defense Meteorological Satellite Program's Operational Linescan System (DMSP/OLS) nighttime stable light (NSL) have good potential estimating EPC effectively at large scales. However, saturated lighted pixels contained within NSL limit accuracy estimation. We developed a new method to correct pixels, using SPOT VEGETATION (SPOT/VGT) 10-day synthesis product (S10) normalized difference vegetation index (NDVI) then modeled Mainland China from 2000 2008. results demonstrated reliability our approach with an average R value 0.93 (P<0.001) relative error −28.92%. showed annual growth rate 13.46% during study period 1198.23 billion kWh 3290.51 billio...
