In this two-year project, CWB weather stations at Taipei, Banchiao, Da-an Park (2016 new site) 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. It also provides the reference for the consistency of long-term meteorological dataset. The goals in the first year include: (1)quantitative estimation on environmental roughness (factor of view) in each weather station (2)simulation on the wind and solar radiation disturbance by builds. (3) investigation on anthropogenuous heat soursessurrounding the sites (4) investigation on urban heat island of Taipei Basin and the cooling effect by Da-an Park. (5) evulation on the data quality from campus weather network。We expect the results could provide the evaluation items for the movement of Banchiao station and the reference for new sites selection.都市氣象粗糙度都市熱島大安森林公園urban meteorologyroughnessurban heat islandDa-an Park
