Soil temperature is the bulk temperature of the soil, not the surface (skin) temperature. "Soil" means the near-surface layer where plants sink their roots. For subsurface temperatures that extend beneath the soil layer or in areas where there is no surface soil layer, the standard name temperature_in_ground should be used.

For subsurface temperatures that extend beneath the soil layer or in areas where there is no surface soil layer, the standard name temperature_in_ground should be used. 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.

For subsurface temperatures that extend beneath the soil layer or in areas where there is no surface soil layer, the standard name temperature_in_ground should be used. 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).
