The perceived air_temperature derived from either a combination of temperature and wind (wind_chill_of_air_temperature) or temperature and humidity (heat_index_of_air_temperature) for the indicated hour. When the air_temperature falls to 283.15 K or less, wind chill will be used for the apparent_air_temperature. When the air_temperature rises above 299.817, the heat index will be used for apparent_air_temperature. Between 283.706 and 299.817 K, the apparent_air_temperature will be the ambient air_temperature.

Air temperature is the bulk temperature of the air, not the surface (skin) temperature. The quantity with standard name apparent_air_temperature is the perceived air temperature derived from either a combination of temperature and wind (which has standard name wind_chill_of_air_temperature) or temperature and humidity (which has standard name heat_index_of_air_temperature) for the hour indicated by the time coordinate variable. When the air temperature falls to 283.15 K or below, wind chill is used for the apparent_air_temperature. When the air temperature rises above 299.817 K, the heat index is used for apparent_air_temperature. For temperatures between 283.706 and 299.817K, the apparent_air_temperature is the ambient air temperature (which has standard name air_temperature).
