Worldwide network of spectrophotometers calibrated at NOAA

The Dobson ozone spectrophotometer network took a vital step toward worldwide calibration with a recent intercomparison test in the United States. Scientists from Denmark, the United Kingdom, Canada, the Soviet Union, Japan, Australia, Egypt, and the German Democratic Republic brought their instruments to the National Oceanic and Atmospheric Administration (NOAA) Air Resources Laboratories in Boulder, Colorado, for calibration. NOAA's spectrophotometer was recommended by the World Meteorological Organization (WMO) as the primary reference standard for total ozone observations.
