Mt. Tsukuba is an isolated mountain with two peaks located in the eastern Kanto plain, about 70 km northeast of Tokyo. History of meteorological observation datas backs to the 1900's, when the Central Meteorological Observatory was constructed within the former Ministry of the Interior. The Japan Meteorological Agency continued modern automatic meteorological observations by AMeDAS till 2001. To continue the long history of observation, the University of Tsukuba established an automatic weather station (AWS) in Dec. 2005 at one of the peaks (Nantai-san, 871 m a.s.l.) under a research project entitled "Multi Monitoring of Meteorological and Hydrological Elements qt Mt. Tsukuba and Analysis for Atmosphere and Water Cycles" (Hayashi, 2006). The AWS not only measures the basic meteorological elements, such as temperture, humidity, wind, radiation, pressure, precipitation, but also monitors the CO2 concentration, weather parameters, pH in the precipitation, and captures the environmental scene around theAWS by digital camera. The platform is introduced by the web site ( where real-time data are also shown. Among the measurements, basic surface meteorological data are made available to the international community via CEOP2 project.
