Weather satellites promise vast benefits to mankind
The U S Air Force began sensor development in 1958 leading to civilian uses. Multispectral imagers read visible and non visible bands and reveal Earth features unseen by the eye. Nimbus III and its improved version forecast temperatures over most of the globe, aiding farming, shipping, travel, and utilities. Advanced weather data could save billions and help ice break up on the St Lawrence Seaway. Studies tie into ecology, climate, and natural resource management.
