Hi Phil--I was reviewing a paper and noting the differences during World War
II and thought up another potential bias that I wonder if is being corrected
for in the ship measurements. Namely, what I am wondering is if account was
taken of the likely different loading (and so height of measurement--for air
and water) of the ships as they went east and west. Basically, the ships
were heavy laden going east and virtually empty coming back, and so there
might well be a need to correct the observations accordingly.
Just a thought--as the only place the models and observations seem different
is over the ocean during WWII.
