c. GFDL shortwave: Eta operational scheme. Two-stream multi-band scheme withozone from climatology and cloud effects (99). (This scheme is well-tested for WRF-NMM, used operationally at NCEP.) Note: If it is desired to run GFDL with amicrophysics scheme other than Ferrier, a modification to module_ra_gfdleta.F isneeded to comment out (!) #define FERRIER_GFDL.d. Modified GFDL shortwave: Similar to the GFDL shortwave (c), but modified to besuitable for tropics (98). (This scheme is well tested and used operationally at NCEPfor HWRF.) New in Version 3.2.e. CAM scheme: from the CAM 3 climate model used in CCSM. Allows for aerosolsand trace gases (3).f. RRTMG shortwave. A new shortwave scheme with the MCICA method of randomcloud overlap (4).g. Held-Suarez relaxation. A temperature relaxation scheme designed for idealizedtests only (31).Surface Layer (sf_sfclay_physics)a.MM5 similarity: Based on Monin-Obukhov with Carslon-Boland viscous sub-layerand standard similarity functions from look-up tables (sf_sfclay_physics = 1). (Thisscheme has been preliminarily tested for WRF-NMM.)b. Eta similarity: Used in Eta model. Based on Monin-Obukhov with Zilitinkevichthermal roughness length and standard similarity functions from look-up tables (2).(This scheme is well tested for WRF-NMM, used operationally at NCEP.)c. NCEP Global Forecasting System (GFS) scheme: The Monin-Obukhov similarityprofile relationship is applied to obtain the surface stress and latent heat fluxes using aformulation based on Miyakoda and Sirutis (1986) modified for very stable andunstable situations. Land surface evaporation has three components (directevaporation from the soil and canopy, and transpiration from vegetation) following theformulation of Pan and Mahrt (1987) (3). (This scheme has been preliminarily testedfor WRF-NMM.)d. Pleim-Xiu surface layer (7).e. QNSE surface layer. Quasi-Normal Scale Elimination PBL scheme’s surface layeroption (4).f. MYNN surface layer. Nakanishi and Niino PBL’s surface layer scheme (5).WRF-NMM V3: User’s Guide 5-5
g. GFDL surface layer (88): (This scheme is well tested and used operationally atNCEP for HWRF.)Land Surface (sf_surface_physics)a. 5-layer thermal diffusion: Soil temperature only scheme, using five layers(sf_surface_physics = 1).b. Noah Land Surface Model: Unified NCEP/NCAR/AFWA scheme with soiltemperature and moisture in four layers, fractional snow cover and frozen soil physics.New modifications are added in Version 3.1 to better represent processes over icesheets and snow covered area (2). (This scheme is well tested for WRF-NMM, usedoperationally at NCEP.)c. RUC Land Surface Model: RUC operational scheme with soil temperature andmoisture in six layers, multi-layer snow and frozen soil physics (3). (This scheme hasbeen preliminarily tested for WRF-NMM.)d. Pleim-Xiu Land Surface Model. Two-layer scheme with vegetation and sub-gridtiling (7).e. GFDL slab model. Used together with GFDL surface layer scheme (88). (Thisscheme is well tested and used operationally at NCEP for HWRF.) New in Version3.2.Planetary Boundary layer (bl_pbl_physics)a. Yonsei University scheme: Non-local-K scheme with explicit entrainment layer andparabolic K profile in unstable mixed layer (bl_pbl_physics = 1). (This scheme hasbeen preliminarily tested for WRF-NMM.)b. Mellor-Yamada-Janjic scheme: Eta operational scheme. One-dimensionalprognostic turbulent kinetic energy scheme with local vertical mixing (2). (Thisscheme is well-tested for WRF-NMM, used operationally at NCEP.)c. NCEP Global Forecast System scheme: First-order vertical diffusion scheme ofTroen and Mahrt (1986) further described in Hong and Pan (1996). The PBL height isdetermined using an iterative bulk-Richardson approach working from the groundupward whereupon the profile of the diffusivity coefficient is specified as a cubicfunction of the PBL height. Coefficient values are obtained by matching the surfacelayerfluxes. A counter-gradient flux parameterization is included (3). (This scheme iswell tested and used operationally at NCEP for HWRF.) Updated in Version 3.2.d. MRF scheme: Older version of (a) with implicit treatment of entrainment layer aspart of non-local-K mixed layer (99).WRF-NMM V3: User’s Guide 5-6
