WMO and JMA did the one-year field intercomparion on 11~18 types of air temperature/radiation shelter in Algeria Africa and Tsukuba Japan individually. Central Weather Bureau (CWB) has setup 5 typs of thermos-sensors, 8 types of radiation shelters (including big wooden screen) to form 19 combinations in NTU-AS meteorological fence and will collect 2-year (Sept.,2019~Aug. 2021) inter-comparison data. This proposal focus on the data analysis from NTU-AS site and survey the docuements and skill from international literature. The goal is to provide the reference for the correction on long-term air temperature data archive, and the decision support for new system instrumentation. We will also help CWB to build up the intercomparison site at Xinwu weather station in 2021.氣溫戶外比對輻射遮罩air temperaturefield intercomparisonradiation shelter
