Climate ESRL's Global Monitoring Division conducts sustained observations and research related to global distributions, trends, sources and sinks of atmospheric constituents that are capable of forcing change in the climate of the Earth. This research will advance climate projections and provide scientific policy-relevant, decision support information to enhance society's ability to plan and respond.

Ozone ESRL's Global Monitoring Division conducts research on the depletion of the global stratospheric ozone layer and Antarctic ozone hole through global surface-based monitoring of total-column ozone, ultraviolet radiation, and ozone-depleting gases, including those regulated by the Montreal Protocol. Continued surveillance is necessary in order to verify the expected recovery of the ozone layer.

Air Quality ESRL's Global Monitoring Division monitors levels of air quality elements such as tropospheric ozone, carbon monoxide and aerosol particles in non-source regions which may be affected by long range transport from distant sources of industrial pollution. This large-scale transport affects baseline air quality which must be monitored in order to determine the importance of regional sources that may impact the environment and public health.

Research Groups

  • Global Greenhouse Gas Reference Network

    The GGGRN makes measurements of the spatial and temporal distributions of greenhouse gases and provides essential constraints to our understanding of the global carbon cycle.
  • Halocarbons and other Trace Species

    The HATS group quantifies the distributions and magnitudes of the sources and sinks for important ozone-depleting and greenhouse gases.
  • Aerosols

    The goals of this program are to characterize means, variability, and trends of climate-forcing properties of different types of aerosols.
  • Solar and Infrared Radiation

    Activities involve empirical and theoretical research of the Earth's surface radiation budget.
  • Ozone and Water Vapor

    Research on the nature and causes of the depletion of the stratospheric ozone layer and the role of ozone and water vapor in forcing climate change.
  • Observatory Operations

    NOAA/ESRL operates staffed atmospheric baseline observatories from which numerous in situ and remote atmospheric and solar measurements are conducted.
