Solar Backscatter Ultraviolet Radiometer (SBUV/2)

NSSDCA ID: 1988-089A-05

Mission Name: NOAA 11
Principal Investigator:Dr. Fred G. Cunningham


The Solar Backscatter Ultraviolet Radiometer (SBUV/2) is designed to provide the vertical distribution of ozone in the earth's atmosphere. The instrument design is based upon the technology developed for the SBUV/TOMS flown on the Nimbus 7. The SBUV/2 instrument measures backscattered solar radiation in an 11.3-degree field-of-view in the nadir direction at 12 discrete, 1.1 nm wide, wavelength bands between 252.0 and 339.8 nm. The solar irradiance is determined at the same 12 wavelength bands by deploying a diffuser which will reflect sunlight into the instrument field-of-view. The SBUV/2 can also measure the solar irradiance or the atmospheric radiance with a continuous spectral scan from 160 nm to 400 nm in increments nominally 0.148 nm. The SBUV/2 has another narrowband filter photometer channel, called the cloud cover radiometer (CCR), which continuously measures the earth's surface brightness at 380 nm. The CCR field-of-view is 11.3 degrees.
