Welcome to NESL

 NESL's Mission: To advance understanding of weather, climate, atmospheric composition and processes; to provide facility support to the wider community; and, to apply our research results to benefit society.

About NESL

Formed in 2010, the NCAR Earth System Laboratory brings together NCAR's major lines of scientific inquiry . Research within NESL is highly collaborative, with specialties focused in the following three research divisions:

The Atmospheric Chemistry Division (ACD) explores the impact of chemistry on climate and air quality.
More about ACD »

The Climate & Global Dynamics Division (CGD) examines Earth's climate system, analyzing the observed environment and developing models capable of predicting the evolution of the climate system.
More about CGD »

The Mesoscale & Microscale Meteorology Division (MMM) seeks to further our understanding of key scientific questions in meteorology, with emphases on both understanding and forecasting weather as well as weather's relationship to climate.

NESL in the News

Severe thunderstorm east of Denver, 5/21/14
Founded on an NCAR-based research model, the new High-Resolution Rapid Refresh (HRRR) model will transform how the National Weather Service predicts short-range weather threats. The model features hourly updates and the ability to simulate individual thunderstorms.
