<DIV>List,</DIV>
<DIV> </DIV>
<DIV>I dumped the contents of an eta 48hr grib file using grib2ctl to a
control file so I could use GrADS to plot surface pressure and precip.
However I couldn't help but notice that the units for Surface Convective
Precip were in kg/m^2. Pardon my ignorance, as I've never actually
plotted precip contours before, but how does this convert into inches or even
centimetes? The values produced seemed suspiciously high, similar to
something you might see in a convective feedback situation, and I was
wondering if there is some sort of conversion factor I'm not aware of, or if I
should literally expect 4" liquid equivalent in a 3 hr period? </DIV>

<DIV>Thanks,</DIV>
