Newly Published NOAA Technical Report on the Current State of Climate and Earth System Modeling at NOAA

A NOAA/OAR Technical Report titled “NOAA Holistic Climate and Earth System Model Strategy Phase I:
 Current State” has been published by the Climate Program Office/MAPP program. CPO/MAPP co-developed this report led by Dave DeWitt with staff at the Geophysical Fluid Dynamics Laboratory (GFDL), National Centers for Environmental Prediction Environmental (NCEP) and the Earth System Research Laboratory (ESRL) as part of a two-phased study to help define NOAA’s strategy for climate and earth system modeling. As the study’s phase-I report, it defines the current state of, and plans for, NOAA’s climate and earth system models developed at GFDL, ESRL, and the NCEP Environmental Modeling Center, with a focus on global coupled models used for research and operations for the subseasonal to centennial timescale. By providing a high-level overview of the current state and future plans of the NOAA climate and earth system model enterprise, it is anticipated that this report will serve as a resource for managers and scientists interested in learning about the current status of the NOAA models. The report lays the groundwork for a planned second phase of the study, whose ultimate goal is to present potential future model development pathways contributing to the definition of a holistic strategy to advance NOAA global climate and earth system models for research and operations.

Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2017, the United States experienced a record-tying 16 climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 362 lives, and had significant economic effects on the areas impacted, costing more than $306 billion. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
