physiological_equivalent_temperature degree_C [UPAA] P07 id: BSJMY3X7
Physiological equivalent temperature (PET) is an equivalent air temperature of the actual thermal condition. It is the air temperature of a reference condition without wind and solar radiation at which the heat budget of the human body is balanced with the same core and skin temperature. Note that PET here is not potential evapotranspiration. In order to convert the units correctly, it is essential to know whether a temperature is on-scale or a difference. Therefore this standard strongly recommends that any variable whose units involve a temperature unit should also have a units_metadata attribute to make the distinction. It is strongly recommended to include the attribute units_metadata.

It is the air temperature of a reference condition without wind and solar radiation at which the heat budget of the human body is balanced with the same core and skin temperature. Note that PET here is not potential evapotranspiration. It is strongly recommended that a variable with this standard name should have a units_metadata attribute, with one of the values "on-scale" or "difference", whichever is appropriate for the data, because it is essential to know whether the temperature is on-scale (meaning relative to the origin of the scale indicated by the units) or refers to temperature differences (implying that the origin of the temperature scale is irrevelant), in order to convert the units correctly (cf. https://cfconventions.org/cf-conventions/cf-conventions.html#temperature-units).
