Abstract. Wild fires exerts strong influences on the environment, ecology, economy and public security. However, the existing hourly JMA-Himawari fire product presents large uncertainties and not suitable for reliable real-time fire monitoring in China. To fill this gap, we proposed an adaptive hourly NSMC-Himawari fire product for China based on the original Himawari source by employing a dynamical threshold for fire-extraction and a database of ground thermal sources. According to the visually-extracted reference and consistence check, we found NSMC-Himawari fire product effectively removed a majority of false fire alarms included in the JMA-Himawari fire product. Based on a rare field-collected ground reference dataset, we evaluated the reliability of JMA-Himawari and NSMC-Himawari fire product across China. The overall accuracy of JMA- Himawari fire product was 54 % and 59 % (not considering the omission errors) respectively. As a comparison, by identifying more real fire pixels and avoiding a majority of false fire alarms, the overall accuracy of NSMC-Himawari fire product was 80 % and 84 % (not considering the omission errors) respectively, making it an ideal source for improved real-time fire monitoring across China. This research also provides useful reference for employing local dataset of underlying surfaces and thermal sources to enhance the accuracy of global fire products in specific regions.

Short summary
Currently, Himawari-8 fire product is the mainstream fire product with the highest temporal resolution, yet presents large uncertainties and not suitable for reliable real-time fire monitoring in China. To address this issue, we proposed an adaptive hourly NSMC (National Satellite Meteorological Center)-Himawari fire product for China, the overall accuracy increased from 54 % (original Himawari product) to 80 %. This product can largely enhance real-time fire monitoring and relevant research.
