Why has "the" been left out before the phrase surface temperature in the sentence below.(It is from Crash Course Astronomy#14.)

Venus's thick atmosphere also means (the) surface temperature is about the same averywhere on the planet.

It is unclear to me why the speaker has left the out becouse it is clear that he was talking about the surface temperature of Venus, not in general about surface temperature.

Because "surface temperature" follows so closely behind "Venus" it is clear that that is what surface temperature it is referring to, not surface temperatures in general.


The omission of the definite article in this example is a grammatical error. We're speaking about a specific surface temperature—that of the planet Venus. We'd omit the article only when speaking about "surface temperature" in a general way, e.g., "Surface temperature is commonly measured using a pyrometer."
