The dynamical tropopause used in interpreting the dynamics of the upper troposphere and lower stratosphere. There are various definitions of dynamical tropopause in the scientific literature. It is strongly recommended to include a units_metadata attribute.

GRIB:

The dynamical tropopause used in interpreting the dynamics of the upper troposphere and lower stratosphere. There are various definitions of dynamical tropopause in the scientific literature. 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.

GRIB:

The dynamical tropopause used in interpreting the dynamics of the upper troposphere and lower stratosphere. There are various definitions of dynamical tropopause in the scientific literature. 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).
