surface temperature
Outer heat reading
Surface temperature is the temperature measured at the outer boundary of an object, whether a planet, body of water, or material.
For Earth, it typically refers to air temperature near ground level or the temperature of land and ocean surfaces.
In astronomy, a star's surface temperature determines its color and spectral classification.
The planet's surface temperature varies dramatically between day and night.
The term distinguishes external temperature from internal or core temperatures.
