Class Documentation

class scale_wind_speed : public filter_base

Scales a wind speed from a given height to the standard reference height in CHM, 50 m Uses a snow roughness z0, but assumes no snow depth (can be corrected for later).

Requires:

• Windspeed [ \(m \cdot s^{-1} \) ]

Modifies:

• None

Provides:

• Reference windspeed at reference height - “U_R” [ \(m \cdot s^{-1} \) ]

Configuration keys:

{
    "variable":"u",
    "Z_F":10
}

variable

Name of the wind variable in the met file

Z_F

Type:

string

Type:

double

Units:

[\(m\)]
