Validation of Ozone Measurements From the SBUV/2 and OMI Data Sets (original) (raw)

Abstract

Ozone is an important atmospheric constituent that shields the Earth's surface from harmful ultraviolet radiation and also plays a critical role in radiation forcing, thus affecting climate change. NOAA's second generation Solar Backscatter Ultraviolet Instruments (SBUV/2) employ the nadir-viewing backscattered ultraviolet technique to measure ozone concentration profiles in the atmosphere on a global scale. The Ozone Monitoring Instrument (OMI) is an imaging spectrometer with daily global coverage that measures columns of gases like ozone, NO2, BrO, and SO2. A comparison of the ozone data sets from SBUV/2 and OMI is discussed for the period when data are available from those experiments. The study of consistency among the data sets of various instruments is important in developing confidence in those data records and in determining their value in trend analyses. In order to establish the validity of the ozone data records, one needs to show that different measurement techni...
