This site, offered by the US National Aeronautics and Space Administration (NASA), provides “the results and ongoing data studies for the study of ozone and other gases, aerosols, radiances, and ultraviolet radiation, and what has been learned about atmospheric pollution and air quality from the international science missions making these measurements.” More specifically users can access tropospheric composition data, obtained using ultraviolet and visible spectroscopy, for total ozone concentrations, aerosol index, radiative cloud fraction, surface UV flux, cloud fraction, as well as the atmospheric concentrations of pollutant gases such as sulphur dioxide, nitrogen dioxide, formaldehyde, bromine monoxide and chlorine dioxide. Active dates for the available atmospheric composition records depend on the instrument used to collect the data, with some datasets dating back to 1978. The site also provides information about the specific instruments used to collect these measurements and documentation on how to download and interpret the available datasets.
