General Field Definitions
---- 3D fields ---- NX x NZ x NY u = wind in east direction [m/s] v = wind in north direction [m/s] w = wind in vertical direction [m/s] (possibly scaled by dx/dz)
p = pressure [pa] th = potential temperature [K]
qv = water vapor (mixing ratio) [kg/kg] cloud = cloud water [kg/kg] ice = cloud ice [kg/kg] qrain = rain mixing ratio [kg/kg] qsnow = snow mixing ratio [kg/kg] qgrau = graupel mixing ratio [kg/kg] nice = ice number concentration [1/cm^3] nrain = rain number concentration [1/cm^3]
---- 2D fields ---- NX x NY
---- moisture fluxes ----
rain = rain+crain+snow+graupel [mm]
crain = convective rain at surface [mm]
snow = snow at surface [mm]
graupel = graupel at surface [mm]---- energy fluxes ---- sensible_heat = Sensible heat flux from surface [W/m^2] latent_heat = Latent heat flux from surface [W/m^2] pbl_height = Height of the planetary boundary layer [m]
---- Radiation variables ---- cloudfrac = Cloud fraction [0-1] swdown = Shortwave down at land surface [W/m^2] lwdown = Longwave down at land surface [W/m^2] lwup = Lonwave up from the land surface [W/m^2]
---- Land Surface variables ---- 3D fields ---- NX x NZ x NY (NZ = number of soil layers) soil_t = 3D Soil temperature [K] soil_vwc = 3D Soil volumetric water content [m^3/m^3]
3D fields ---- NX x NY x N_Times (typically 1 or 12) vegfrac = vegetation cover fraction [%]
2D fields ---- NX x NY skin_t = Land surface skin temperature [K] soil_tdeep = Temperature at the soil column bottom [K] snow_swe = Snow water equivalent on the land surface [mm] soil_totalmoisture = Soil column total water content [mm] soil_type = Soil type (index for SOILPARM.TBL) [1-n] veg_type = Vegetation type (index for VEGPARM.TBL) [1-n] landmask = Map of Land vs Water grid cells [0,1,2]
---- NOTE ---- dX_dt variables are the increment in boundary conditions between internal model time steps some of these are 2d, some are 3d
---- model structure ---- terrain = surface elevation [m] z = model layer height (at mid point) [m] dz = layer thickness [m]
sintheta = sine of the angle between grid and geographic coords [] costheta = cosine of the angle between grid and geographic coords [] fzs = buffered FFT(terrain) for linear wind calculations
