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 developed upon NCAR’s Advanced Research WRF (ARW); integrates NASA’s advanced physics modules, Land Information System, satellite simulators, and ensemble data assimilation system; and can be driven by GEOS-5 and MERRA. NU-WRF is used to investigate various earth science phenomena including aerosol, cloud, precipitation, and land processes and their interactions. NU-WRF is one of three major earth system modeling systems funded by NASA’s Modeling Analysis and Prediction (MAP) program. Read more...
