Nighttime light remote sensing provides a unique perspective on monitoring human activities and socioeconomic conditions. However, early studies nighttime lighting usually neglected the evaluation of source detection luminance conditions in underdeveloped areas. Recent have identified significant underestimation effect areas, which makes it difficult to use as valid proxy for other variables. To address this problem, paper proposes method based reconstruction. Missing luminous pixels will be using rich information provided by daily-scale data blooming patterns, diverse ancillary utilized regression reconstruction values supplement annual correct effect. The effectiveness was verified from 7,776 townships areas China. results demonstrated that proposed corrected NPP/VIIRS improved accuracy 23.23% 17.71% at village township scales, respectively. correlations between night variables were also improved. Spearman's rank correlation coefficients population, GDP, electricity consumption county scale increased 0.045, 0.020, 0.018, agriculture-related different degrees both scales. can contribute improving modeling correcting This provide better support sustainable development studies.
