Abstract:
The Stratospheric Aerosol and Gas Experiment I (SAGE I) instrument was
launched on board the Applications Explorer Mission-2 (AEM-2)
satellite, which was dedicated to the SAGE I mission. SAGE I provided
global data collection of aerosol vertical extinction profiles, ozone
vertical concentration profiles, and nitrogen dioxide vertical
concentration profiles. The SAGE I instrument was a Sun
... photometer
that measured the attenuation of solar radiation in four spectral
regions through the Earth's atmosphere during spacecraft sunrise and
sunset. The solar radiance data were combined with spacecraft
ephemeris and National Oceanic and Atmospheric Administration (NOAA)
meteorological data and then numerically inverted to yield altitude
profiles of aerosol extinction at wavelengths of 1000 and 450 nm and
altitude profiles of ozone and nitrogen dioxide concentration.
The SAGE I aerosol data were validated by comparison with correlative lidar
and dustsonde in situ measurements. These data are currently archived at
the the EOSDIS Langley DAAC in Hampton, Virginia. These data are archived
in the Hierarchical Data Format (HDF).
