The Modeling, Analysis, Predictions and Projections Program Mission

The Modeling, Analysis, Predictions, and Projections (MAPP) Program's mission is to enhance the Nation's and NOAA's capability to understand, predict, and project variability and changes in Earth's climate system. MAPP’s work directly impacts or provides foundational capability for improving understanding, assessing impacts for decision making, and improving NOAA products used in mitigation and adaption. By supporting these goals, the MAPP program plays a crucial role in enabling the Nation to meet the societal challenges created by the impacts of climate variability, such as year-to-year changes in the occurrence of extremes or droughts, and longer term climate changes.

U.S. citizens and businesses face unprecedented challenges resulting from variations in the climate. Our growing National infrastructure is increasingly susceptible to both year-to-year and long-term changes in climate conditions. To prepare for and understand the nature of these changes, accurate and regional-scale computational modeling of the climate system is of the utmost importance. Climate and Earth system models and derived prediction systems have become central to almost every aspect of the global change research and applications apparatus.

NOAA is motivated by the challenges facing society to improve products and services through research. Ensuring that marine resources are sustainable; understanding coastal vulnerabilities and ensuring resiliency; monitoring, predicting, and understanding droughts; and preparing for extremes -- each of these critical aspects of our socioeconomic system are directly dependent upon our improved capability to model and predict aspects of the climate system. NOAA’s MAPP Program sustains research that is critical to improving such a foundational capability.

Supporting the infusion of innovation into services and practice

  • MAPP partners with the NIDIS Program to support research directed toward advancing the Nation's ability to understand, monitor and predict droughts. This research fosters improved responses to the impacts of climate on a major challenge facing U.S. citizens -- the availability of water resources. Learn more…
  • NCEP's Climate Test Bed (CTB), which supports the transfer of research into NOAA operational activities, partners with the MAPP program to entrain research results into NOAA products. The emphasis of this relationship is placed on testing and evaluating advances in climate modeling and prediction for operations. By supporting the transition of research into products and services, MAPP program engagement with the Climate Test Bed helps ensure that MAPP’s research outcomes ultimately make a difference in the information society receives to deal with challenges stemming from climate variability and change.

Enhancing scientific interactions

  • Coordination and communication is key to optimize return on research investments, enhancing research outcomes and impacts. The MAPP Program engages in an array of activities that aim at enhancing communication and coordination within the community of funded investigators and beyond. The communication and facilitation engendered by the MAPP program’s efforts described below support NOAA’s collective fulfilment of the Climate Goal, a further demonstration of the value of competitive grants in fostering collaboration.
  • The MAPP Task Forces, primarily involving funded investigators, are organized around our major ongoing research initiatives to coordinate and focus research efforts and to assist in the entrainment of research findings toward advances in relevant National and NOAA climate-related activities. More information is available, at the links below.
  • MAPP hosts a monthly webinar series which provides a platform for MAPP-funded researchers to present their research to the larger community, and for the MAPP program to expose its portfolio of funded projects and strategic directions to the broader community. The webinars are advertised widely to the community of MAPP-funded investigators, NOAA laboratories and operational centers, other federal agency laboratories, and the private sector. To date, the webinar series has attracted over 800 attendees. The webinars also serve as a platform to encourage climate literacy in the public, as a portion of the series’ attendees either do not have a background in climate science or do not have expertise with a particular webinar topic
  • MAPP contributes to enhanced communications between NOAA's research labs, NOAA's operational centers and external partners. To this end, MAPP has organized and attended many workshops to date, including GFDL-NCEP Ocean Modeling Meeting, the Climate Prediction Task Force Virtual Workshop on Bias Corrections inSubseasonal to Interannual Predictions, the U.S. Climate Modeling Summit, and the NMME Sub-seasonal Forecast System Exploratory Workshop. All meetings and workshops hosted by MAPP can be found here.
  • MAPP program management participates in U.S. Global Change Research Program interagency groups (e.g. the Interagency Group for Integrative Modeling) to identify the potential for partnerships with other agencies' programs on objectives of common interest. Examples of projects that have been jointly funded by NOAA/MAPP and other agencies include the Center for Ocean-Land-Atmosphere Studies and the National Multi-Model Ensemble (NMME) Experiment (forecasts available here).
  • Interagency partnerships are also fostered through the World Climate Research Program (WCRP) Program, including the CLIVAR and GEWEX Programs. MAPP program management participates in the US-CLIVAR interagency group.
