All of these (except weather, visibility and cloud-related meteorological elements) are observed automatically. At unstaffed stations, observations are performed every 10 minutes. About 700 of the unstaffed stations observe precipitation, air temperature, wind direction and speed, and sunshine duration, while the other stations observe only ...
The installation was completed on August 15, 1964, [1] and is now recorded on the list of IEEE Milestones in electrical engineering.When first built, the Mount Fuji Radar System was the world's highest weather radar (elevation 3,776 metres [12,388 ft]), and could observe major weather phenomena, such as destructive typhoons, at a range of more than 800 kilometres (500 mi).

Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
The first operational CPS-9 was installed at Maxwell AFB, Alabama, on 20 June 1954; that radar remained operational for 30 years before finally being replaced on 14 July 1984 by a more modern radar, the AN/FPS-77 (Fuller 1990a). In 1966, the Air Weather Service still had 40 CPS-9s in operation. By 1974, the number was reduced to 11.

The second planned project is the Bistatic Adaptable Radar Network (BARN) which will be integrated with existing DOWs and the COW to provide high resolution wind vector observations without the need for multiple, expensive transmitters. These bistatic receivers will consist of small antennas that can be deployed like Pods or mounted onto a ...
