AntennaTemperature
type: Class
subclass of: Temperature
comment: Antenna temperature is a way of expressing the brightness of a radiation source - it is proportional to the power per unit area emitted by the source. In most cases where it is used it corresponds to the thermodynamic or physical temperature of the source being observed. It thus relates the power emitted by the source to an interesting physical property of that source.

BrightnessTemperature
type: Class
subclass of: Temperature
comment: A descriptive measure of radiation in terms of the temperature of a hypothetical blackbody emitting an identical amount of radiation at the same wavelength.

DewPoint
type: Class
equivalent class: DewPointTemperature
subclass of: Temperature
comment: The temperature to which a given air parcel must be cooled at constant pressure and constant water vapor content in order for saturation to occur.

EffectiveTemperature
type: Class
subclass of: Temperature
comment: The temperature at which motionless saturated air would induce, in a sedentary worker wearing ordinary indoor clothing, the same sensation of comfort as that induced by the actual conditions of temperature, humidity, and air movement. Effective temperature is used as a guide in air-conditioning practice, and, on the comfort chart (American Society of Heating and Air Conditioning Engineers), it appears as a family of curves that serves as one coordinate in defining comfort zones.

WindChillIndex
type: Class
subclass of: Temperature
equivalent class: WindChill
subclass of: Restriction
  on property: measureOf
  all values from: Wind
comment: A means of quantifying the threat of rapid cooling during breezy or windy conditions that may result in hypothermia in cold conditions.

PotentialTemperature
type: Class
subclass of: Temperature
subclass of: Restriction
  on property: hasState
  has value: Adiabatic
comment: The temperature that a parcel would have if brought adiabatically and reversibly from its initial state to a standard reference pressure, typically 100 kPa.

WetBulbPotentialTemperature
type: Class
subclass of: PotentialTemperature
comment: The temperature an air parcel would have if cooled from its initial state adiabatically to saturation, and thence brought to 1000 mb by a moist-adiabatic process.
