Wet-bulb potential temperature, sometimes referred to as pseudo wet-bulb potential temperature, is the
temperature
Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measurement, measured with a thermometer.
Thermometers are calibrated in various Conversion of units of temperature, temp ...

wet-bulb temperature, it were brought at the
saturated adiabatic lapse rate to the standard pressure of 1,000 mbar.
This temperature is conservative with respect to
reversible adiabatic
In thermodynamics, an isentropic process is an idealized thermodynamic process that is both adiabatic and reversible. The work transfers of the system are frictionless, and there is no net transfer of heat or matter. Such an idealized process ...

Equivalent temperature
In atmospheric science, equivalent temperature is the temperature of air in a parcel from which all the water vapor has been extracted by an adiabatic process.
Air contains water vapor that has been evaporated into it from liquid sources (lake ...
