Earth System Research Laboratory

The Earth System Research Laboratory (ESRL) is a laboratory in National Oceanic and Atmospheric Administration's (NOAA) Office of Oceanic and Atmospheric Research (OAR). It is one of seven NOAA Research Laboratories (RLs) and is located in Boulder, Colorado.

ESRL combines six separate NOAA labs under one organization with four Divisions - Global Monitoring, Physical Sciences, Chemical Sciences, and Global Systems. The former labs falling into ESRL are the Aeronomy Laboratory, the Climate Diagnostics Center, the Climate Monitoring and Diagnostics Laboratory, the Environmental Technology Laboratory, the Forecast Systems Laboratory, and the Surface Radiation Research Branch of the Air Resources Laboratory.

The goal of the Global Monitoring Division (GMD) is to conduct long-term, continuous measurement of atmospheric gases, particles and radiation in order to understand climate forcing, ozone depletion and air quality. This information will be used to support global and regional decisions, climate projections and carbon management.

The Physical Sciences Division (PSD) conducts research to understand the physical environment: the atmosphere, ocean, cryosphere, and land in order to improve local to global weather and climate predictions.

The Chemical Sciences Division (CSD) studies chemical processes in the Earth's atmosphere that affect climate, air quality, and the ozone layer.
