Definition

  • [Image Source: NOAA, http://www.ozonelayer.noaa.gov/action/sbuv2.htm ] [Text Source: NASA POES Project home page, http://goespoes.gsfc.nasa.gov/poes/instruments/sbuv.html ] The SBUV/2 is a nadir-pointing nonspatial spectrally scanning ultraviolet radiometer carried in two modules. The two modules are the Sensor Module with the optical elements/detectors and the Electronics Module. The overall radiometric resolution is approximately 1 nanometer (nm). Two optical radiometers form the heart of the instrument: a monochrometer and a “Cloud Cover Radiometer” (CCR). The monochrometer measures the Earth radiance directly and selectively the Sun when a diffuser is deployed. The CCR measures the 379-nm wavelength and is coaligned to the monochrometer. The output of the CCR represents the amount of cloud cover in a scene and is used to remove cloud effects in the monochrometer data. The SBUV/2 measures solar irradiance and Earth radiance (backscattered solar energy) in the near ultraviolet spectrum (160 to 400 nm). The following atmospheric properties are measured from this data: - The global ozone concentration in the stratosphere to an absolute accuracy of 1 percent. - The vertical distribution of atmospheric ozone to an absolute accuracy of 5 percent. - The long-term solar spectral irradiance from 160 to 400 nm Photochemical processes and the influence of “trace” constituents on the ozone layer.
