Outline of Final Research Achievements

Field observation data of heat flux to atmosphere from vegetation and satellite data of land surface is used in order to evaluate effect of vegetation on urban atmospheric heat environment. Temperature difference between urban surface (without vegetation) and various urban vegetation such as park, agriculture field, and suburban forest is investigated with focus on multi-scale temporal variation (daily, seasonal, and inter-annual). Although vegetation field is generally cooler than urban surface, some exception is observed as follows; surface temperature is warmer in agriculture field during wintertime and occasionally heat flux from forest surface is compatible to those of urban surface even in summertime. If we miss to consider vegetation types and composites of urban vegetation field, we should overestimate cooling effect of vegetation.
