'''AMeDAS''' ('''''A''utomated ''Me''teorological ''D''ata ''A''cquisition ''S''ystem'''), commonly known in [[Japanese language|Japanese]] as "アメダス" (''amedasu''), is a high-resolution [[surface observation]] network developed by [[Japan Meteorological Agency]] (JMA) used for gathering regional weather data and verifying forecast performance. Begun operation on November 1, 1974, the system consists of about 1,300 stations with automatic observation equipment. These stations, of which more than 1,100 are unmanned, are located at an average interval of 17 km throughout [[Japan]].

Line 11:

All the observational data is transmitted to the AMeDAS Center at JMA Headquarters in [[Tokyo]] on a [[Real-time computing|real time]] basis via telephone lines. The data is then delivered to the whole country after a quality check.

ApartAs fromwell as weather conditions, AMeDAS is also used in the observation of [[natural disaster]]s. Temporary observation points are set up in areas where there are signs of [[volcanic eruption]]s or [[earthquake]]s.
