Climate Monitoring and Diagnostics Laboratory (NOAA)

Project Description
The Climate Monitoring and Diagnostics Laboratory (CMDL) of the
National Oceanic and Atmospheric Administration, conducts sustained
observations and research related to source and sink strengths, trends
and global distributions of atmospheric constituents that are capable
of forcing change in the climate of Earth through modification of the
atmospheric radiative environment, those that may cause depletion of
the global ozone layer, and those that affect baseline air
quality. CMDL accomplishes this mission primarily through long-term
measurements of key atmospheric species at sites spanning the globe,
including four fully-equipped Baseline Observatories. These key
species include carbon dioxide, carbon monoxide, methane, nitrous
oxide, surface and stratospheric ozone, halogenated compounds
including CFC replacements, hydrocarbons, sulfur gases, aerosols, and
solar and infrared radiation. The measurements are of the highest
quality and accuracy possible, and document global changes in key
atmospheric species, which are all affected by mankind, identifying
sources of interannual variability. In addition, research programs in
key regions, utilizing an array of platforms including aircraft,
balloons, ocean vessels and towers, complement the land-based
information. CMDL's data are used to assess climate forcing, ozone
depletion and baseline air quality, to develop and test diagnostic and
predictive models, and to keep the public, policy makers, and
scientists abreast of the current state of our chemical and radiative
atmosphere.
