Nimbus-7
Nimbus-7 was a sun-synchronous polar-orbiting satellite launched by NASA in 1978. It was designed to collect data on the Earth's atmosphere, oceans, and land surfaces. The satellite carried a suite of instruments including the Stratospheric and Mesospheric Sounder (SAMS), the Limb Infrared Monitor of the Stratosphere (LIMS), and the Coastal Zone Color Scanner (CZCS). SAMS measured temperature and pressure in the upper atmosphere, while LIMS measured the distribution of ozone and other gases in the stratosphere. CZCS provided information on the color of the ocean, which could be used to determine the concentration of phytoplankton and other organic matter. Nimbus-7 operated for over a decade, providing valuable data for climate research and weather forecasting.
