Hi Dave,
Inquiry: When I try to display Potential Vorticity for this file: ftp://ftp/pub/incoming/chop.pgbanl.fnl.2004081000 in the default contour plan view, I get the following error: An error has occurred: ControlDescriptor.Creating display org.python.core.PyException
This is a known problem: http://www.unidata.ucar.edu/software/idv/docs/userguide/Bugs.html#faq1_cat3_14"Any derived quantity that involves a derivative (e.g., divergence, vorticity) and is produced from a grid
with a lat/lon domain will give incorrect results or not work."
I am cc'ing Don on this and he may be able to shed further light on this
when he gets back next week.
Don - Dave's file is in /upc/share/metapps/test/bugs -Jeff
