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_a3hl6	snow 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

    Mdata	meteorological forcing
    Xdata	snow profile data
    runCanopyModel	should the canopy module also be called?
    adjust_height_of_wind_value	should the height of wind values be adjusted?

compRadiation()

void Meteo::compRadiation	(	const SnowStation &	station,
		mio::SunObject &	sun,
		SnowpackConfig &	cfg,
		CurrentMeteo &	Mdata
