Abstract
Establishing dynamic and timely industrial emissions inventory accurately is usually challenging due to a long update cycle of the time‐consuming bottom‐up methods. The daily Visible Infrared Imaging Radiometer Suite (VIIRS) thermal anomaly product at a high resolution of 375 m can detect spatial location and fire radiative power (FRP) of thermal anomalies including industrial heat sources. We explore potential of VIIRS product in updating industrial emission inventory. Industrial heat sources in China are identified and further compared with industrial emissions from Multi‐resolution Emission Inventory for China. The correlations (R2) between VIIRS FRP and industrial emissions are 0.86 in regions dominated by coal‐consuming activities and 0.9 for these with fragmented small‐scale plants and light industries. Our results suggest that VIIRS thermal product can provide a dynamic and quantitative constraint of activation levels and spatial allocation of emission from industrial heat sources.
Plain Language Summary
The combustion of fossil fuels in global industrial activities emits a large amount of atmospheric pollutants and greenhouse gases every year, which is considered as the main anthropogenic factor causing air pollution and climate change. Owing to a comprehensive estimation of the diverse industrial emissions, bottom‐up methods usually have a time‐consuming compilation process for years. Satellites provide near‐real‐time observations of atmospheric composition, which are useful constraints for updating emissions inventories timely. However, there are only several satellite products of atmospheric components with reliable accuracy by now. In this study, we present a probing insight into the application potential of Visible Infrared Imaging Radiometer Suite (VIIRS) thermal anomaly product with a high resolution of 375 m for updating industrial emissions inventory of China. Comparison of VIIRS fire radiative power (FRP) in industrial heat sources and Multi‐resolution Emission Inventory for China industry emission shows similar spatial patterns for both their location and magnitude. By analyzing the correlation of satellite FRP and emission inventory, our results suggest that the high‐resolution satellite thermal anomaly product can provides a dynamic and quantitative constrain for industry emission levels and reallocation of industrial heat sources
Key Points
Industrial heat sources in China are identified by Visible Infrared Imaging Radiometer Suite (VIIRS) thermal anomaly products
VIIRS fire radiative power has high correlations with industrial emission
