ESRL/GMD Atmospheric Transport Data
Entry ID: NOAA_ESRL_Atmospheric_Transport

Abstract: NOAA/ESRL/GMD's mission is to observe and understand, through accurate, long-term records of atmospheric gases, aerosol particles, and solar radiation, the Earth's atmospheric system controlling climate forcing, ozone depletion and baseline air quality, in order to develop products that will advance global and regional environmental information and services.

Description: NOAA/ESRL's Global Monitoring Division (formerly 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.

GMD 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.

GMD'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.

GMD?s vision and mission support the broader objectives of NOAA?s Strategic Plan and are aligned with the vision and mission of the Office of Oceanic and Atmospheric Research (OAR).

Description: The GOSIC Portal provides convenient, central,one-stop access to data and information identified by the Global Climate Observing System (GCOS), the Global Ocean Observing System (GOOS) and the Global Terrestrial Observing System (GTOS) and their partner programs, such as the Global Atmosphere Watch (GAW).
