84 hour Extension
Extension of the 00z & 12z Meso Eta 22 km parallel runs began on IBM Phase II on 14 November 2000.
Displays have been viewable http://www.emc.ncep.noaa.gov/mmb/mmbpll/etapll_ext/
Operational strategy is to perform 24 hour extension as separate job to maintain 60 hr product timeliness. Normally, the extension will complete before AVN starts.
