PRES.txt

CORe uses a non-hydrostatic version of the FV3GFS model.  So
the PRES in the grib files is the full pressure.  The FV3
model uses a sigma-pressure coordinates.  However, the previous
pressure is the hydrostatic pressure which is a measure of the 
mass in the layer.  So in the stratosphere, the layers are
of constant (hydrostatic) pressure.  The full pressure is not constant.
I took a single analysis, and found the mean, min and max values of the 
layer pressure.  Note that the values are in Pa.
