Near-global ozone for September 6, 2004, by TOMS-EP. The Total Ozone Mapping Spectrometer (TOMS) was a NASA satellite instrument, specifically a spectrometer, for measuring the ozone layer. Of the five TOMS instruments which were built, four entered successful orbit. The satellites carrying TOMS instruments were: Nimbus 7; launched October 24 ...
Ozone Mapping and Profiler Suite (OMPS), is a suite of instruments built by Ball Aerospace that measure the global distribution of ozone and, less frequently, how it is distributed vertically within the stratosphere. [1] The suite flies on the Suomi NPP and NOAA-20 (formerly JPSS-1) satellites along with several other instruments.
Technician preparing the SBUV/2 instrument for calibration in a vacuum chamber at Ball Aerospace in Boulder, CO. The Solar Backscatter Ultraviolet Radiometer, or SBUV/2, is a series of operational remote sensors on NOAA weather satellites in Sun-synchronous orbits which have been providing global measurements of stratospheric total ozone, as well as ozone profiles, since March 1985.
Dobson spectrophotometers can be used to measure both total column ozone and profiles of ozone in the atmosphere. [5] [6] Ozone is tri-atomic oxygen, O 3; ozone molecules absorb harmful UV light in the atmosphere before it reaches the surface of the earth. No UVC radiation penetrates to the ground as it is absorbed in the ozone-oxygen cycle.
However, estimates of surface UV radiation from satellite data (ozone and cloud cover) started in November 1978 with the launch of Nimbus-7/TOMS (Total Ozone Mapping Spectrometer) followed by Meteor-3/TOMS in 1991, Earth-Probe/TOMS in 1996, and by OMI (Ozone Measuring Instrument on the EOS/AURA spacecraft) in July 2004.
The ozone monitoring instrument (OMI) [1] is a nadir-viewing visual and ultraviolet spectrometer aboard the NASA Aura spacecraft, which is part of the satellite constellation A-Train. In this group of satellites Aura flies in formation about 15 minutes behind Aqua satellite , both of which orbit the Earth in a polar Sun-synchronous pattern, and ...
Fourier Transform Infrared spectrometer (column abundances of a broad range of species including ozone, HCl, NO, NO 2, ClONO 2, and HNO 3). MkIV observations . The MkIV Interferometer is a Fourier Transform Infra-Red (FTIR) Spectrometer, designed and built at the Jet Propulsion Laboratory in 1984, to remotely sense the composition of the Earth ...
Observation was furthered by succeeding missions such as Nimbus 7, fitted with a coastal zone colour scanner (CZCS) for detailing colour changes in the Earth's oceans, and a Total Ozone Mapping Spectrometer (TOMS) to measure solar irradiance and the reflected radiance from the Earth's atmosphere.
