The Nimbus satellites were second-generation U.S. robotic spacecraft used for meteorological research and development.
On board the Nimbus satellites are various instrumentation for imaging, sounding, and other studies in different spectral regions.
The seven Nimbus satellites, launched over a fourteen-year period, shared their space-based observations of the planet for thirty years.
The global coverage provided by Nimbus satellites made accurate 3-5 day forecasts possible for the first time.
Even before the Nimbus satellites began collecting their observations of Earth's ozone layer, scientists had some understanding of the processes that maintained or destroyed it.
Nimbus satellites collected orbital data on the extent of the polar caps in the mid-1960s, recorded in the visible and infrared parts of the spectrum.
The Weddell Sea Polynya has not been observed since the event witnessed by the Nimbus satellites in the mid-70s.
A Nimbus satellite launched in 1968 failed to reach orbit.
After all, their findings flatly contradicted those reported by an American Nimbus satellite in orbit since 1978.
Since 1979, two instruments aboard the Nimbus 7 satellite have provided a richer set of data, covering virtually the entire globe every day.
