NOAA Earth System Research Laboratory

The Earth System Research Laboratory was formed to pursue a broad and comprehensive understanding of the Earth system. At the ESRL scientists study atmospheric and other processes that affect air quality, weather, and climate. ESRL researchers monitor the atmosphere, study the physical and chemical processes that comprise the Earth system, and integrate those findings into environmental information products. Their work improves critical weather and climate tools for the public and private sectors, from hourly forecasts to international science assessments with policy-relevant findings.
 The website includes sections on:

• Understanding the atmospheric mechanisms that drive Earth's climate
• Assuring the continuing health and restoration of atmospheric resources
• Improving predictions  through expanded climate and weather products
