Which term describes the curvature of the airfoil on the upper surface relative to the chord line?

Explanation:
Camber describes how much the airfoil’s surface bows away from the straight chord line, and the curvature on the upper surface relative to that line is upper camber. This measures how much the top surface curves upward away from the chord. The bottom surface curvature would be lower camber, while the trailing edge is simply the rear point where the surfaces meet, not a measure of curvature.
