The High Resolution Rapid Refresh (HRRR): Recent and future enhancements, time-lagged ensembling, and 2010 forecast evaluation activities

The first hourly-updated, 3-km storm-resolving model, the HRRR (High-Resolution Rapid Refresh), is being run at NOAA/ESRL/GSD and is nested within the Rapid Update Cycle (RUC) and future replacement, the Rapid Refresh (RR). The breakthrough with the HRRR is the development of an effective technique for assimilating 3-d radar reflectivity data in...

NOAA's hourly-updated 3km HRRR and RUC/Rapid Refresh - recent (2010) and upcoming changes toward improving weather guidance for air-traffic management

NOAA's hourly-updated 3-km High-Resolution Rapid Refresh (HRRR), run experimentally at NOAA's Earth System Research Laboratory, has become a cornerstone for FAA's experimental ATM demonstrations and for the multi-agency Consolidated Storm Prediction for Aviation (CoSPA). A major 2010 demonstration has allowed closer scrutiny of HRRR (and related...

Improvements to Lake-Effect Snow Forecasts Using a One-Way Air–Lake Model Coupling Approach

Lake-effect convective snowstorms frequently produce high-impact, hazardous winter weather conditions downwind of the North American Great Lakes. During lake-effect snow events, the lake surfaces can cool rapidly, and in some cases, notable development of ice cover occurs. Such rapid changes in the lake-surface conditions are not accounted for i...

Use of VIIRS Aerosol Optical Depth Information at NOAA GSL to Improve Smoke, Visibility, and Weather Forecasts in the Experimental High Resolution Rapid Refresh

Recent wildfires in the U.S. and abroad have underscored the far-reaching effects that smoke from wildfires has on lives and industries, impacting air quality, aviation, solar energy generation, and more. As a result, demand has increased for reliable and accurate forecasts of smoke emanating from wildfires. To a...

Application of the High-Resolution Rapid Refresh (HRRR) to the Bay Area Advanced Quantitative Precipitation Information Project

The Bay Area Flood Protection Association has just recently begun funding the Physical Sciences Division and Global Systems Division (GSD) of NOAA’s Earth System Research Lab (NOAA-ESRL), as well as the NOAA Cooperative Institute for Research in the Atmosphere (CIRA), to design and build a specialized nowcast / forecast system for the 9 Californ...

Addressing Common Cloud - Radiation Errors from ~4-hour to 4-week Model Prediction

Cloud-radiation representation in models for subgrid-scale clouds is a known gap from subseasonal-to-seasonal models down to storm-scale models applied for forecast duration of only a few hours. NOAA/ESRL has been applying common physical parameterizations for scale-aware deep/shallow convection and boundary-layer mixing over this wide range of ...
