In this two-year project, CWB weather stations at Taipei, Banchiao, Da-an Park (proposed site in 2017) and campus weather station in Xinsheng Elementary School of Taipei, will be revised on the environmental impact and build the evaluation procedure on the movement of meteorological sites. In the first year, we have revised the environmental roughness (instrumental exposure) and artificial heat sources. Air flow and sun shadowing simulation over 3-D street canopy are also conducted. The heat-wave case of July 27, 2016 in metropolitan Taipei was studied with campus meteorological network data to check the hot-spots in Taipei city. We also made linkages among CWB, Taipei City Hall and Taiwan Forestry Research Institute for cooperation on urban meteorology monitoring. The goals in the second-year progres are (1) more intestigation on the wind and solar radiation disturbance simulation by building surrounding weather stations. (2) more campus network data-denied case studies on Taipei heat-island phenomenon. (3) detailed site review of new auto-weather site besides MRT Tu-Cheng hangar to provide CWB guideline for site selection and movement of auto meteorological stations in the future.都市氣象粗糙度都市熱島大安森林公園urban meteorologyroughnessurban heat islandDa-an Park
