Along with its predecessor SMMR, the SSM/I contributes to an archive of global passive microwave products from late 1978 to present.
Information within the SSM/I TBs measurements allow the retrieval of four important meteorological parameters over the ocean: near-surface wind speed (note scalar not vector), total columnar water vapor, total columnar cloud liquid water (liquid water path) and precipitation. Accurate and quantitative measurement of these parameters from the SSM/I TBs is, however, a non-trivial task. Variations within the meteorological parameters significantly modify the TBs. As well as open ocean retrievals, it is also possible to retrieve quantitatively reliable information on sea ice, land snow cover and over-land precipitation.

“We are the products of editing, rather than of authorship.”
—George Wald (b. 1906)
“It seemed there was a sort of poisoning, an auto-infection of the organisms, so Dr. Krokowski said; it was caused by the disintegration of a substance ... and the products of this disintegration operated like an intoxicant upon the nerve-centres of the spinal cord, with an effect similar to that of certain poisons, such as morphia, or cocaine.”
—Thomas Mann (1875–1955)
“But, most of all, the Great Society is not a safe harbor, a resting place, a final objective, a finished work. It is a challenge constantly renewed, beckoning us toward a destiny where the meaning of our lives matches the marvelous products of our labor.”
—Lyndon Baines Johnson (1908–1973)
