Abstract
This study compares transpiration results using surface temperature method (ST method) and heat pulse velocity. ST method calculates transpiration using image data of surface temperature and energy budget data. Heat pulse velocity by heat pulse method correlates with transpiration of a tree. Surface temperature was low and estimated transpiration using ST method was high at trees where heat pulse velocity is high. The variations of difference of transpiration by ST method are found to be similar to those of heat pulse velocity at Sugi and Hinoki forests. Mapping of transpiration using ST method at forests are ascertained by such results.
