metpy.calc.el(pressure, temperature, dewpt, parcel_temperature_profile=None)[source]

Calculate the equilibrium level.

This works by finding the last intersection of the ideal parcel path and the measured environmental temperature. If there is one or fewer intersections, there is no equilibrium level.

  • pressure (pint.Quantity) – The atmospheric pressure
  • temperature (pint.Quantity) – The temperature at the levels given by pressure
  • dewpt (pint.Quantity) – The dew point at the levels given by pressure
  • parcel_temperature_profile (pint.Quantity, optional) – The parcel temperature profile from which to calculate the EL. Defaults to the surface parcel profile.

pint.Quantity, pint.Quantity – The EL pressure and temperature
