Terra Aerosol, Cloud and Tropospheric Chemistry Data Sets Available From the NASA Langley ASDC

Data from three instruments currently flying aboard the Terra satellite whose measurements include aerosols, clouds, and tropospheric chemistry are available from the NASA Langley Atmospheric Sciences Data Center (ASDC). The Clouds and the Earth's Radiant Energy System (CERES) instrument measures broadband radiative fluxes at the top of the atmosphere along with cloud and aerosol properties. The Multi-angle Imaging SpectroRadiometer (MISR) instrument obtains precisely calibrated images at nine different viewing angles and four wavelengths to provide radiance, aerosol, cloud and land surface data. The Measurement of Pollution in the Troposphere (MOPITT) instrument makes global measurements of methane and carbon dioxide concentrations. The Terra satellite, part of NASA's Earth Observing System (EOS) satellite series, was launched on December 18, 1999. The NASA Langley Atmospheric Sciences Data Center archives and distributes data from all three of these instruments. Data, tools and information are available at the ASDC web site, http://eosweb.larc.nasa.gov.
