[Met_help] Met software on Blueice?

MET was written and tested using the GNU g++ and g77 compilers which are freely available.  I haven't run on Ubuntu Linux before, but I assume you'd be able to use the GNU compilers.

In the future, we hope to support a wider range of platform/compiler combinations.

A few issues have shown up with the beta version of MET that's currently available.  Specifically in regards to winds and specific humidity.  The current version of MET isn't converting the point
observation values for specific humidity to the correct units before comparing it to the forecasts (that's in point_stat).  Also, in regards to winds, the model typically defines winds relative to the
grid directions while the point observations define winds relative to the earth.  MET is not currently accounting for this difference.

For the next release by the end of December, those two issues will be fixed.  The specific humidity observations will be converted to the proper units prior to verification.  And the grid-relative
model winds will be rotated to be earth-relative prior to verification.  And there are several enhancements that have been added as well.

So it's your choice.  You could try running with the beta version that's currently available.  Or wait for the next version at the end of December.

Either way, we're happy to answer any questions that come up in your installation and running.
