Upper Atmosphere Research Satellite Upper Atmosphere Research Satellite The Upper Atmosphere Research Satellite (UARS) was a NASA-operated orbital observatory whose mission was to study the Earth’s atmosphere, particularly the protective ozone layer. The satellite was deployed from Space Shuttle "Discovery" during the STS-48 mission on 15 September 1991. It entered Earth orbit at an operational altitude of , with an orbital inclination of 57 degrees. The original mission duration was to be only three years, but was extended several times. When the mission finally ended in June 2005 due to funding cuts, 14 years after the satellite's launch, six of its ten instruments were
Office of Oceanic and Atmospheric Research second generation of CHARM is underway to help answer questions about greenhouse warming effects on Great Lakes water quantity. NOAA researchers closely monitor the Earth's atmosphere searching for clues about long-term changes in the global climate. The data collected worldwide by NOAA researchers contributes to the understanding of complex climatic systems and the ability to forecast changes. NOAA Research organizations conduct research on the upper and lower atmosphere as well as the space environment. Their findings form the basis for NOAA's contributions to major national and international environmental programs and agreements. For instance, improvements in forecast and warning services provided
