Ray Pierrehumbert answered that a long while ago at RC, you can probably find it there if you search for "science fair" -- the trick is replicating both the dense air at the bottom of the column and the thin air at the upper atmosphere end, because that makes a difference (that wasn't known at the time) in how IR is absorbed. You might do it with a long tube with a transparent membrane across the middle that could withstand 15 psi, maybe.
