parcel_profile_with_lcl_as_dataset#
- metpy.calc.parcel_profile_with_lcl_as_dataset(pressure, temperature, dewpoint)#
Calculate the profile a parcel takes through the atmosphere, returning a Dataset.
The parcel starts at temperature, and
dewpoint
, lifted up dry adiabatically to the LCL, and then moist adiabatically from there. pressure specifies the pressure levels for the profile. This function returns a profile that includes the LCL.- Parameters
pressure (
pint.Quantity
) – The atmospheric pressure level(s) of interest. This array must be from high to low pressure.temperature (
pint.Quantity
) – The atmospheric temperature at the levels in pressure. The first entry should be at the same level as the first pressure data point.dewpoint (
pint.Quantity
) – The atmospheric dewpoint at the levels in pressure. The first entry should be at the same level as the first pressure data point.
- Returns
profile (
xarray.Dataset
) – The interpolated profile with three data variables: ambient_temperature, ambient_dew_point, and profile_temperature, all of which are on an isobaric coordinate.

Only functions on 1D profiles (not higher-dimension vertical cross sections or grids).
