Air pressure thickness from pressure at interface

• Description: Produces pressure thickness at each level from the air pressure at the interface of levels. It takes the difference of the pressure at the top and bottom of the level.

• Name: AirPressureThickness_A

• Variable produced: air_pressure_thickness

• Input Variables: air_pressure_levels

• Number of Levels - One fewer level than air_pressure_levels

• FunctionSpace - The same FunctionSpace as the input air pressure levels Field

• hasTLAD - False

• Optional Parameters: None
