The NASA-Unified Weather Research and Forecasting (NU-WRF) model is an observation-driven regional earth system modeling and assimilation system at satellite-resolvable scale. NU-WRF is one of three major earth system modeling systems funded by NASA’s Modeling Analysis and Prediction (MAP) program.
NU-WRF is designed to study following areas.
- Impacts of land-surface initialization and hydrological data assimilation on mesoscale weather and regional climate.
- Feedbacks and coupling between the land surface and planetary boundary layer.
- High-impact phenomena, such as hurricane, squall line, blizzard, and drought/flood, dust storms, wildfire, heavy pollution events.
- Aerosol-cloud-precipitation interactions.
- Mesoscale processes controlling the variability of aerosols and trace gases.
- Effects of aerosols and trace gases on regional climate and air quality.
- Improve representation of regional water cycle through assimilating precipitation-affected microwave radiance from satellites.
- Semi-operational high-resolution weather forecasting to support NASA’s field campaigns.
- Downscaling NASA’s global modeling and reanalysis for regional climate.
- Supporting current and future satellite missions via satellite simulator.
- Improving CO2 flux and transport process representation via high-resolution simulation of the surface state and weather.
