  • Set flag for land and ice points.

– number of soil categories

– set parameters for IGBP land-use data

  • Save land-related prognostic fields for guess run.
  • Prepare variables to run RUC LSM:
    • 1. configuration information (c):
      ffrozp - fraction of frozen precipitation
      frpcpn - .true. if mixed phase precipitation available
      1:im - horizontal_loop_extent
      fice - fraction of sea-ice in the grid cell
      delt - timestep (sec) (dt should not exceed 3600 secs)
      conflx2 - height ( \(m\)) above ground of atmospheric forcing variables
      lsoil_ruc - number of soil layers (= 6 or 9)
      zs - the depth of each soil level ( \(m\))
  • 2. forcing data (f):
    sfcprs - pressure at height zf above ground (pascals)
    sfctmp - air temperature ( \(K\)) at height zf above ground
    q2 - pressure at height zf above ground (pascals)
    qcatm - cloud water mising ration at height zf above ground ( \(kg !kg^{-1}\))
    rho2 - air density at height zf above ground (pascals)
  • 3. canopy/soil characteristics (s):
    vtype - vegetation type (integer index)
    stype - soil type (integer index)
    sfcems - surface emmisivity -> sfcemis
    sfalb_lnd_bck - backround snow-free surface albedo (fraction) -> albbck_lnd
    snoalb - upper bound on maximum albedo over deep snow -> snoalb1d_lnd
  • Prepare land/ice/water masks for RUC LSM
  • 4. history (state) variables (h):
    cmc - canopy moisture content ( \(mm\))
    soilt = tskin - ground/canopy/snowpack effective skin temperature ( \(K\))
    soilt1 = snowpack temperature at the bottom of the 1st layer ( \(K\))
    tslb(lsoil_ruc) - soil temp ( \(K\)) -> stsoil
    smois(lsoil_ruc) - total soil moisture content (volumetric fraction) -> smsoil
    sh2o(lsoil_ruc) - unfrozen soil moisture content (volumetric fraction) -> slsoil
    smfrsoil(lsoil_ruc) - frozen soil moisture content (volumetric fraction) -> smfrsoil
    keepfrflag(lsoil_ruc) - flag for frozen soil physics: 0. or 1.
    wet - soil moisture availability at surface
    snowh_lnd - actual snow depth ( \(m\))
    sneqv_lnd - liquid water-equivalent snow depth ( \(m\))
    sncovr_lnd - fraction of snow in the grid cell
    chh_lnd - surface exchange coefficient for heat ( \(m s^{-1}\)) -> chs
    z0_lnd - surface roughness ( \(m\)) -> zorl( \(cm\))
    qsfc_lnd - specific humidity at surface ( \(kg kg^{-1}\))

– sanity checks on sneqv and snowh

  • Call RUC LSM lsmruc() for land.
  • RUC LSM: prepare variables for return to parent model and unit conversion.
    • 6. output (o):
      lh - actual latent heat flux ( \(W m^{-2}\): positive, if upward from sfc)
