Member Function Documentation

◆ compHSrate()

bool Meteo::compHSrate ( CurrentMeteo Mdata,
const SnowStation Xdata,
const double &  hs_a3hl6 
)
static

Compute measured snow depth change rate to detect growing grass (canopy) vs. snowfall on bare ground.

Parameters
Mdata
Xdata
hs_a3hl6snow depth average from t_now - 6 h to t_now - 3 h
Returns
whether grass should be detected

◆ compMeteo()

void Meteo::compMeteo ( CurrentMeteo Mdata,
SnowStation Xdata,
const bool  runCanopyModel,
const bool  adjust_height_of_wind_value 
)
  • with CANOPY set: In case of an existing canopy, call canopy routine, which computes precipitation, radiation, friction velocity and reference temperature for the surface below the canopy. Note that solar radiation may change also in dg_cn_Canopy().
    • Mdata->iswr incoming global solar radiation (direct + diffuse), adapted to canopy
    • Mdata->rswr reflected global solar radiation (diffuse), adapted to canopy
    • Mdata->ustar friction velocity, adapted to canopy
    • Mdata->z0 roughness length, adapted to canopy
    • Mdata->ea atmospheric emissivity below canopy, i.e., to give correct longwave radiation as function of air temperature, however modified to include effect of canopy
  • without canopy (CANOPY is not set): For bare soil as well as snowed-in canopy or some other problems, compute the roughness length z0, the friction velocity ustar as well as the atmospheric stability correction psi_s for scalar heat fluxes
    • Mdata->ustar friction velocity
    • Mdata->z0 roughness length
    • psi_s stability correction for scalar heat fluxes
      Parameters
      Mdatameteorological forcing
      Xdatasnow profile data
      runCanopyModelshould the canopy module also be called?
      adjust_height_of_wind_valueshould the height of wind values be adjusted?
