Weather satellite satellite data. Collectively, weather satellites flown by the U.S., Europe, India, China, Russia, and Japan provide nearly continuous observations for a global weather watch. As early as 1946, the idea of cameras in orbit to observe the weather was being developed. This was due to sparse data observation coverage and the expense of using cloud cameras on rockets. By 1958, the early prototypes for TIROS and Vanguard (developed by the Army Signal Corps) were created. The first weather satellite, Vanguard 2, was launched on February 17, 1959. It was designed to measure cloud cover and resistance, but a poor axis
Weather Underground of Hong Kong Weather Underground of Hong Kong Weather Underground of Hong Kong (Chinese: 香港地下天文台, pinyin: xiānggǎng dìxià tiānwéntái) is a non-profit website established in 1995 and directed by Mr. Fong Chi Kong Clarence. The website provides a wide range of information related to weather and climate. Air temperature, relative humidity, barometric pressure, rain and wind chill can be found on the site. Radar and satellite views are also included in order to provide more comprehensive weather data to users. Information about local weather comes mainly from the Hong Kong Observatory (HKO), which collects data from foreign weather organizations, for example, satellite data
