Reliable ETA80 Grib data containing dewpoint data

[Daniel Leins]

I should have mentioned this in my prior messages..

The formula I'm using to derive dewpoint is the following:

'define satvapprs=6.11*exp(5422*((1/273.16)-(1/t)))'
'define satmixrat=0.622*satvapprs/(z)'
'define mixrat=satmixrat*rh/100'
'define vapprs=mixrat*z/0.622'
'define dewpoint=13.7*log(vapprs/6.1)'

I'd prefer not to have to take this route, since when I plot a skew-t
and compare the dewpoint trace to the dewpoint trace of a skew-t plotted
within AWIPS or online, there are indeed differences, especially as you
go up through the atmosphere.
