A good understanding of SUEWS is a prerequisite to the proper use of SuPy.
supy.util.cal_z0zdΒΆ
- supy.util.cal_z0zd(ser_qh, ser_ustar, ser_ta_c, ser_rh_pct, ser_pres_hpa, ser_ws, z_meas, h_sfc, debug=False)[source]ΒΆ
Calculates surface roughness and zero plane displacement height. Refer to https://suews-parameters-docs.readthedocs.io/en/latest/steps/roughness-SuPy.html for example
- Parameters
ser_qh (pd.DataFrame) β sensible heat flux [W/m^2]
ser_ustar (pd.Series) β friction velocity [m/s]
ser_ta_c (pd.Series) β air temperature [Β°C]
ser_rh_pct (pd.Series) β relative humidity [%]
ser_pres_hpa (pd.Series) β air pressure [hPa]
z_meas (number) β measurement height in m
h_sfc (number) β vegetation height in m
debug (bool, optional) β Option to output final calibrated
ModelResult
, by default False
- Returns
z0 β surface roughness length for momentum
zd β zero displacement height
