In 1986, when GMCC became the Climate Monitoring and Diagnostics Laboratory and HATS was formed, efforts were initiated to increase the number of gases measured from each flask.

Additionally, the Molecular Diagnostics Laboratory is responsible for providing biochemical testing services in support of the agency's pest monitoring programs.

The reduction is now about 10 to 15 percent, said Ellsworth Dutton, a meteorologist at N.O.A.A.'s Climate Monitoring and Diagnostics Laboratory in Boulder, Colo.

The new analysis, described in the current issue of Geophysical Research Letters, is by the Commerce Department's Climate Monitoring and Diagnostics Laboratory in Boulder, Colo., and the National Institute for Space Research of the Netherlands.

This study was supported by the National Science Foundation under grant OPP-9321547 and NOAA's Climate Monitoring and Diagnostics Laboratory.

At South Pole Station, balloon-borne ozone-measuring instruments launched by the NOAA Climate Monitoring and Diagnostics Laboratory reveal the vertical structure of the developing ozone hole.

"This year, ozone depletion over the South Pole, from 7-to-14 miles above Antarctica, has shown large losses, similar to losses seen in the 1990s," said Bryan Johnson of the NOAA Climate Monitoring and Diagnostics Laboratory.

The Climate Monitoring and Diagnostics Laboratory (CMDL) is part of NOAA's Oceanic and Atmospheric Research (OAR) division.
