Earth System Science and Modeling Division

CPO's Earth System Science and Modeling (ESSM) Division supports research to advance understanding of the Earth system.

To understand and predict changes in climate, weather, oceans, and coasts--so people can protect themselves and their property--we need to understand global patterns and climate variability and change. And to help manage and conserve coastal resources and marine ecosystems, we need to understand and monitor our oceans and coasts.

The ESSM Division is actively building the global and regional scale understanding needed to improve predictions. The program coordinates an array of researchers from federal agencies, national labs, and universities, focusing them on the most pressing climate research necessary to advance NOAA's prediction and other services and applications.

The ESSM Division comprises five programs: Climate Variability & Predictability (CVP), Modeling, Analysis, Predictions, and Projections (MAPP), Atmospheric Chemistry, Carbon Cycle, & Climate (AC4), Climate Observations and Monitoring (COM), and Earth's Radiation Budget (ERB).
