Analysis of Clearance Environment Based on SRTM for China Weather Radar Network

Study and analyze the distribution of weather radar and the clearance environment in China. The SRTM elevation data was used to analyze the beam distance coverage and fixed elevation coverage of the national weather radar network. The statistical analysis of the radar coverage rate of the province in 2015 shows that the coverage rate of the weather radar station network in China has reached 61.54% (covering the land area). However, there is a significant density unevenness in the spatial distribution of weather radar networks, and there are large regional differences in coverage.
