Calibrated Radiance and Solar Radiance
EOSDIS Calibrated Radiance and Solar Radiance Data
These are two interrelated disciplines comprising Spectral/Engineering and Sun-Earth Interactions, both involving radiation. In this context, Spectral/Engineering encompasses whatever data is needed to turn raw instrument data with outputs that may be in the form of voltages or digital counts, for example, into a calibrated, self-consistent set of physical measurements, radiances or backscatter coefficients, say, which in turn can be related through previously derived algorithms to geophysical parameters of interest such as ozone concentration. The calibrated data themselves fall within this discipline. Sun-Earth Interactions involve measurements of radiation coming from the sun (solar irradiance in various spectral regions) as well as solar particle fluxes and their effects on the Earth’s magnetosphere. Earth Observing System Data and Information System (EOSDIS) Distributed Active Archive Centers (DAACs) provide over 800 Spectral/Engineering products from active and passive sensors. All DAACs, except CDDIS and SEDAC, have datasets within this discipline. There are 25 Sun-Earth interaction data sets available from GES DISC, with a few others from ASDC as well as ORNL DAAC.
