NOAA Earth System Research Laboratory

The Earth System Research Laboratory (ESRL) is a division of the National Oceanic and Atmospheric Administration and the U.S. Department of Commerce. Scientists at ESRL study the dynamic physical, chemical, and biological processes that comprise the Earth's atmospheric system. These studies cover such subtopics as climate change, the carbon cycle, air quality, the ozone layer, climate and water systems, and the development of new observing systems, computational infrastructures, and technologies.
