An agro-meteorological database coupled with crop models (MeteoCrop DB) has been developed for studying the impacts of climate change on rice (Oryza sativa L.) in Japan (http://MeteoCrop.dc.affrc.go.jp). MeteoCrop DB consists of daily meteorological data at the Automated Meteorological Data Acquisition System (AMeDAS) stations (about 850 sites across Japan) from 1980 to 2011 and those at the about 160 surface meteorological observatories from 1961 to 2011. These stations cover the whole of Japan and are the main components of the meteorological observation network of the Japan Meteorological Agency. The daily meteorological information in the database consists of both general meteorological elements (air temperature, wind speed, precipitation, sunshine duration etc.) and agro-meteorological elements (solar radiation, humidity, downward longwave radiation, potential evaporation etc.). Since the latter elements are critical for studying rice production but are not measured at the AMeDAS stations, they are estimated for each AMeDAS location from the observed sunshine duration and the observed elements at the neighboring surface meteorological observatory. The models of micro-meteorology in crop canopy and rice growth are run in combination with the agro-meteorological information to estimate the daily mean water temperature in a rice paddy during the growth period, the diurnal change in rice panicle temperature during the flowering period, and phenological stages of the rice plants.
