At a regional airport with an elevation of 29 meters below sea level, the observed station pressure is 1031 mb.

Using the equations presented in the activity, mb must be the station pressure to correctly determine the sea level pressure value in mb.
Group of answer choices

10.31 mb, added to

2.9 mb, subtracted from

10.31 mb, subtracted from

2.9 mb, added to

2.9 mb, subtracted from

Explanation:

Base on the scenario been described in the question, the correct is 2.9 mb, subtracted from

The substraction is because the base station is below or under the sea level and the atmospheric pressure decreases or reduces with the height. I hope this explanation is helpful
