The phrase "a function of ambient" is correct and usable in written English.
It can be used in contexts discussing how something is influenced or determined by the surrounding environment or conditions.
Example: "The performance of the device is a function of ambient temperature and humidity levels."
Alternatives: "dependent on the environment" or "influenced by surroundings".
