About Us

Why a National ESPC? Emerging predictive capabilities internationally in a changing climate require a National initiative to coordinate complex environmental models, deliver forecasts, and coordinate research focus that depends upon:
World-class expertise from multiple agencies that, together, can address the entire problem.
Distributed computing that leverages separate agency resources.
Coordinated sets of agency requirements.
A systems approach to extreme weather prediction, climate change impacts, and future energy efficiencies.

The National Earth System Prediction Capability (ESPC) is an ongoing collaboration between the National Oceanic and Atmospheric Administration (NOAA), U.S. Navy, U.S. Air Force, Department of Energy (DOE), National Aeronautics and Space Administration (NASA), and the National Science Foundation (NSF). The National ESPC builds on progress made by the existing National Unified Operational Prediction Capability (NUOPC) partnership, which is a consortium of Navy, NOAA, and Air Force modelers and their research partners. NUOPC aims to advance the weather prediction modeling systems used by meteorologists, mission planners, and decision makers in part by developing a common model architecture - a standard way of building models - in order to make it easier to collaboratively build modeling systems. To this end, they have already developed a NUOPC Layer that defines conventions and templates for using the Earth System Modeling Framework.


The NUOPC Layer implements a component-based software architecture with the following key features:
  • Four Basic Building Blocks: Driver, Model, Mediator, Connector
  • Many Architectural Options
  • Field Brokering
  • Initialize Sequence
  • Run Sequence
  • Compatibility Testing
  • Compliance Checker
The nation’s security and economic well-being rely upon accurate global analysis and prediction of the physical environment over time scales of a few days to a few decades. This need for better-informed decisions is amplified by recent changes in the climate mean and variability, which reduce the reliability of predictions that use average conditions, combined with the recent extreme events affecting commerce, defense, infrastructure and water, energy and other resources. The National ESPC will improve environmental predictions and help decision makers address critical policy and planning issues by extending the national predictive capability from hours to days to seasonal, annual and decadal time periods through improved, coupled global environmental prediction.

About Us

The Earth System Prediction Capability (ESPC) was formed in 2010, with an updated Charter in 2016, between the original NUOPC partners with the addition of the National Aeronautics and Space Administration (NASA), Department of Energy (DOE), and National Science Foundation (NSF) to improve coordination and collaboration across federally sponsored environmental research and operational prediction communities for scientific development and operational implementation of improved global prediction at the weather-to-climate interface.
