Abstract
Based on the high temporal and spatial resolution of Japanese Himawari-8 geostationary meteorological satellite data and visibility observation data, the band and band combination was selected suitable for daytime sea fog identification in coastal areas of South China, including R0.64, NDVI, BT11.2-BT10.4, BT11.2-BT3.9, BT11.2 etc, and taken into account the influence of solar elevation angle on the reflectivity channel, and constructed a new coastal fog monitoring model (SFM) in the coastal area of South China for the identification of sea fog in the coastal areas of South China And applications. According to the fog judgment standard promulgated by the China Meteorological Administration, the sea fog monitoring model (SFM) was used to remotely monitor the coastal fog events in South China from January to April 2018, and further used the three provinces of South China (Guangxi, Guangdong, Hainan). Visibility data from coastal and island observatories are verified. The results show that the accuracy of sea fog recognition based on SFM model is about 68.6%, which has a good business application prospect.
