|OAR-GMD Carbon Cycle Greenhouse Gases (CCGG)
||The use of fossil fuels and practice of deforestation to meet the world's energy demands
has lead to increasing concentrations of carbon dioxide and methane in the atmosphere.
Both gases absorb terrestrial infrared radiation and have the potential to affect
earth's climate. Before policies can be developed to limit the emissions of these
gases into the atmosphere, their biogeochemical cycling must be understood. The NOAA
CMDL Carbon Cycle Greenhouse Gases group makes ongoing discrete measurements from
land and sea surface sites and aircraft, and continuous measurements from baseline
observatories and tall towers. These measurements document the spatial and temporal
distributions of carbon-cycle gases and provide essential constraints to our understanding
of the global carbon cycle.
