News Items

• Fall 2017 - FV3 realtime runs started. Tests with FV3 are underway with Grell-Freitas convection (C384 - 25km) toward NGGPS development. FV3-GFS .vs. FV3-GFS (Grell-Freitas)
• Nov 2016 - FIM moving toward FV3 -- FV3 coordination and development started with NCEP and GFDL and ESRL/PSD. Some limited FIM experiments with physics and coupled modeling (Week 3-4) will continue as an interim model while initial development on FV3 starts.
• Oct 2016 - 30km FIM experiments continue with alternative cumulus parameterizations comparisons. FIM-30km uses the GFS physics suite including its simplified-Arakawa-Schubert scheme. By contrast, FIMX-alt-30km uses the Grell-Freitas instead of the SAS scheme with the rest of the GFS physics suite otherwise. FIM-15km uses the GFS physics suite, but with use of MODIS land-use data instead of USGS.
