Global Monitoring Laboratory
Total Ozone
The Dobson Ozone Spectrophotometer has been used to study total ozone since its development
in the 1920's. The observations of total ozone, the total amount of ozone
in a column from the surface to the edge of the atmosphere, by this instrument
is one of the
longest geophysical measurements series (at Arosa, Switzerland)
in existence.

Today, the instrument
is an important part of a global effort to understand the role of stratospheric
ozone in atmospheric chemistry, biological and ecological effects of solar
UV radiation, climate and weather. GML maintains 15 stations which use the
Dobson Ozone spectrophotometer for total ozone measurements.
GML hosts the World Meteorological Organization (WMO),
Global Atmosphere Watch
World Dobson Calibration Center
. GML is the custodian of the Dobson World standard instrument D083, which is calibrated at the GML Mauna Loa observatory every two years using the Langley Technique. Dobson regional standards are calibrated to D083 approximately every four years
(http://www.o3soft.eu/dobsonweb/calibrations.html)
. US regional network instruments are also calibrated to D083 at GML headquarters in Boulder, Colorado. Please Contact Glen McConville for additional information.
