Description

SAGE1_AERO_PRF data are Stratospheric Aerosol and Gas Experiment (SAGE) I - Aerosol Profiles in Hierarchical Data Format including altitude profile of aerosol extinction properties at 1000 and 450 nm.The Stratospheric Aerosol and Gas Experiment I (SAGE I) instrument was launched February 18, 1979, on board the Applications Explorer Mission-B (AEM-B) 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 archived at the the EOSDIS Langley DAAC in Hampton, Virginia in the Hierarchical Data Format (HDF).
