TIROS (Television Infrared
Observational Satellite) On
April 1, 1960, TIROS 1,
the first true weather satellite, was launched. With each
succeeding generation of satellites, remote sensing instruments
became increasingly sophisticated and generated finer spectral and
spatial resolution imagery.
Television and Infrared Observation Satellite (TIROS) carried
special television cameras that viewed Earth's cloud cover from a
450 mile orbit. By 1965, nine more TIROS satellites were launched.
They had progressively longer operational times, carried infrared
radiometers to study Earth's heat distribution, and several were
placed in polar orbits to increase coverage over the first TIROS
in its near-equatorial "polar" orbit...
