I am using model data as input 3-D >gridded data. I would like to display wind vectors on isentropic theta >surfaces to show the structure of the winds flowing into storms, etc. How >would I set up an IDV display for winds on isentropic surfaces? At the current time, IDV does not support display of data on isentropic coordinates. It's on our TODO list, but at this point we have no work scheduled on this. >Also does IDV have a gradient operator? I would like to display fields such >as the horizontal gradient of theta to show upper level fronts. Again, there is no way to do this at present. It's on our TODO list.
