For many lives that inhabit inland water bodies such as lakes and reservoirs, water temperature is an important environmental factor-the shift of water temperature may cause to replace some species by others in an ecosystem. On the other hand, some reports indicate that the surface temperatures of some lakes or reservoirs have been increasing with time due to global warming. Thus, water temperature monitoring for inland waters like lakes and reservoirs is important as aspects of biodiversity conservation and global warming monitoring. However, many water bodies except for some large lakes have not fully or never been monitored on water temperature. We therefore have been developing a satellitebased lake and reservoir temperature database (SatLARTD) since 2009. As of August 2011, SatLARTD in Japan (SatLARTD-J) has been nearly completed using thermal infrared (TIR) imagery observed by the ASTER instrument onboard the Terra satellite, providing water surface temperatures for 899 Japanese water bodies greater than a size of 270 m by 270 m (3 by 3 pixels in ASTER/TIR), with daily max/min air temperatures. In the future version, other satellite data like Terra/MODIS will be added for improvement of the temporal resolution. We also wish to extend the target area from only Japan to Asia or the world.
