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 ( R 2 ) 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.
