History

On October 1, 2005, NOAA's Aeronomy Laboratory, Climate Diagnostics Center, Climate Monitoring and Diagnostics Laboratory, Environmental Technology Laboratory, and Forecast Systems Laboratory were merged into four divisions of the newly formed Earth System Research Laboratory. These were the Chemical Sciences Division, Global Monitoring Division, Global Systems Division, and Physical Sciences Division. On April 2, 2020, NOAA designated the four divisions of the Earth System Research Laboratory in Boulder as full laboratories within the NOAA Oceanic and Atmospheric Research line office to meet recent shifts in mission-essential priorities. The four laboratories retained their core research missions and continue to collaborate closely with each other and other NOAA Research laboratories to improve understanding and ability to predict changes in Earth's atmosphere, climate, and weather.
