TOVS Statistics from Five Oceanic Climatic Regions

Cumulative cloud fractions are normalized

by value of layer centered at 500 mb.

Since TOVS retrieves cloud cover and

includes thin clouds as well as convective

anvils the fractional cloud and Tb histogram

data look different:

More of the total cloud cover occurs

above 400 mb.

Correlations of cumulative cloud fraction

and rainfall are smaller at highest levels

(due to non-precipitating cirrus) and

increase downward.
