pyet.meteo_utils.calc_ea

pyet.meteo_utils.calc_ea(tmean=None, tmax=None, tmin=None, rhmax=None, rhmin=None, rh=None, ea=None)

Actual vapor pressure [kPa].

Parameters:

• tmean (array_like, optional) – average day temperature [°C].

• tmax (array_like, optional) – maximum day temperature [°C].

• tmin (array_like, optional) – minimum day temperature [°C].

• rhmax (array_like, optional) – maximum daily relative humidity [%].

• rhmin (array_like, optional) – mainimum daily relative humidity [%].

• rh (array_like, optional) – mean daily relative humidity [%].

• ea (array_like, optional) – actual vapor pressure [kPa].

Returns:

• float or pandas.Series or xarray.DataArray containing the calculated actual vapor

• pressure [kPa].

Examples

>>> ea = calc_ea(tmean, rh)
