The STI Modeling Program Team is responsible for supporting a variety of NWS modeling and research initiatives to improve weather forecasts. This is accomplished by funding research and education projects to accelerate and advance the development of new models, and foster collaboration among NOAA research scientists, federal labs, operational forecasters and the academic community. Examples of programs managed by this program division include efforts to improve guidance for hurricane track, intensity, and storm surge forecasts; develop an end-to-end air quality forecast capability; advance research to extend forecast skill beyond 8-10 days; and implement a weather-scale, fully-coupled numerical weather prediction system.

Round 3 of Research to Operations Initiative: NGGPS, HFIP and NOAA Testbeds Federal Funding Opportunities (FFO) are published on Grants.Gov

Round 3 of Research to Operations Initiative: NGGPS and HFIP NOAA-NWS-NWSPO-2018-2005325

The R2O Initiative is soliciting proposals for projects involving applied science, modeling and/or data assimilation that support development of the NGGPS at global and regional scales. The NOAA R2O Initiative is also soliciting proposals for the Hurricane Forecast Improvement Project (HFIP) initiative to engage and coordinate hurricane research required to improve operational hurricane forecasts and meet societal requirements to effectively mitigate economic disruption. The notice describes opportunities and application procedures to demonstrate capabilities that have the potential to be incorporated into operational NWS numerical weather prediction (NWP) analyses and forecasts. The R2O Initiative addresses NOAA's Weather Ready Nation (WRN) strategic goal and supporting objectives.

Letters of Intent (LOI) are due December 8, 2017. LOI's are strongly recommended.

Full proposals are due February 7, 2018.


Round 3 of Research to Operations Initiative: NOAA Testbeds NOAA-NWS-NWSPO-2018-2005317

Applicants for this opportunity must work in partnership with NOAA testbeds and proving grounds (listed under NOAA's testbeds and proving grounds facilitate the orderly transition of research capabilities to operational implementation through development testing in testbeds, and pre-deployment testing and operational readiness/suitability evaluation in operational proving grounds.

Letters of Intent (LOI) are due December 13, 2017. LOI's are required. Full proposals are due February 7, 2018.

More Accuracy with less precision - assessing information content for reliable weather and climate prediction by Tim Palmer, (Royal Society Research Professor, University of Oxford)


Abstract: The reasons for stochastic parmeterisation are reviewed.  From this, we conclude that conventional 64-bit floating-point representations in NWP and climate models are, for the most part, unnecessary and energetically profligate.  It is argued that a new start is needed for the development of Earth-System Models, based on the primacy of information content.
