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).

Changes in ocean salinity lead to ITCZ migration 13 May 2022

Changes in ocean salinity lead to ITCZ migration

Researchers use coral reef isotopes to investigate changes in ocean salinity and variable ITCZ position.

UV-VIS-NIR Workshop 6/14/2022 12:00 PM - 6/15/2022 3:00 PM

UV-VIS-NIR Workshop

AC4 and ERB in collaboration with NESDIS is organizing a workshop to better understand the needs of atmospheric composition applications and gather recommendations for future UV-Vis-NIR data from the low-earth orbiting (LEO) NOAA satellite missions.

How Will a Warming World Impact El Niño? 5 May 2022

How Will a Warming World Impact El Niño?

ENSO is a major source of seasonal predictability and driver of global climate and extreme events. Changes in the seasonal evolution of ENSO during its onset and decay phases have received little attention by the research community. A new study published in Nature Communications aims to better understand these changes and ENSO’s impact.

NOAA’s observations help inform U.S. greenhouse gas emissions reporting for hydrofluorocarbons 25 April 2022

NOAA’s observations help inform U.S. greenhouse gas emissions reporting for hydrofluorocarbons

For the first time, the U.S. Environmental Protection Agency (EPA) has included a comparison of NOAA’s atmospheric emission estimates of four hydrofluorocarbons (HFCs) to its own inventory-based estimates in the just-released U.S. Inventory of Greenhouse Gas Emissions and Sinks, based on results first reported in the 2017 Geophysical Research Letters study by a team of NOAA, CIRES, and EPA scientists.

New Global Forecasts of Marine Heatwaves Foretell Ecological and Economic Impacts 20 April 2022

New Global Forecasts of Marine Heatwaves Foretell Ecological and Economic Impacts

Researchers have developed global forecasts that can provide up to a year's advance notice of marine heatwaves, sudden and pronounced increases in ocean temperatures that can dramatically affect ocean ecosystems.
