hydromt.model.processes.meteo.press_correction(dem_model: DataArray, g: float = 9.80665, r_air: float = 8.3144621, mo: float = 0.0289644, lapse_rate: float = -0.0065) → DataArray[source]#

Pressure correction based on elevation lapse_rate.

Parameters:

  • dem_model (xarray.DataArray) – DataArray with high res lat/lon axis and elevation data

  • g (float, default 9.80665) – gravitational constant [m s-2]

  • R_air (float, default 8.3144621) – specific gas constant for dry air [J mol-1 K-1]

  • Mo (float, default 0.0289644) – molecular weight of gas [kg / mol]

  • lapse_rate (float, deafult -0.0065) – lapse rate of temperature [C m-1]

Returns:

press_fact – pressure correction factor

Return type:

xarray.DataArray
