> Question 1 At Northern Colorado Regional Airport near Fort Collins, Colorado, elevation 5016 feet above sea- level, the observed station pressure is 24.77 in Hg. 1) Adjust this station pressure to a sea-level pressure value estimate, to the nearest hundredth of an inch of Hg. 2) Show your work for the calculation in 1) by either typing the steps of your solution into this answer box OR attaching an image of your handwritten work as a submission comment after submitting this quiz. 3) "Reality check" your answer - i.e., why is your calculated value for the sea-level pressure estimate reasonable in comparison to the given station pressure?
