WRF EMS V3.1.1 Beta Release Announcement - 6 November 2009

Greetings All!

Greetings All,

I am pleased, and yet exhausted, to announce the availability of WRF EMS V3.1 beta

 http://strc.comet.ucar.edu/wrfems

The V3.1 beta release is an update to the original EMS V3.0 beta 2 distribution, which was made available last March. This update fixes many issues that were brought to my attention over the past 6 Months as well as the inclusion of additional functionality.  There are far too many changes from the V3 releases to list here, but the major update is the inclusion of the ARW and NMM WRF V3.1.1 cores.

NOTE: This will be the final release before the official V3.1 is available in December. Until that time I will be writing the full documentation that is sorely lacking from the current EMS. So, if you encounter any problems that I have not addressed please being them to me attention soon so that I can get them into the update.

Installation of the WRF EMS requires the use of ems_install.pl, which was developed to tackle all the challenges that you might encounter if you were to attempt a manual installation of the EMS.  It is highly recommend that you use the most current version of this routine as your life will become less complicated and more rewarding if you do. And that’s a statement only a few modeling systems can make!

So, “Where might I get this current WRF EMS ems_install.pl utility thing” you ask?

NOAA users of the WRF EMS may simply request the current version of the install routine from the SOO Science and Training Coordinator (SOO STRC). All non-NOAA users, i.e., everyone else, must first register for the WRF EMS.
