Hi all, I set up a formula in IDV to plot thermal wind vectors, a la:<derived description="thermal wind in a layer" formula="thrm(F1,user_Top_of_Layer[default=500],user_Bottom_of_Layer [default=1000])" id="thermalWind" isdefault="false" isenduser="true">
Whenever I do this on a GRIB2 format grid file, e.g. realtime NAM or GFS from the motherlode or atm-nsf opendap servers, I end up with all missing data when I load in the formula, specify my levels, and choose the 3D geopotential height from the GRIB2 file.
If I do the same on the same model data that has been converted to GEMPAK, and also with the sample model data used in the IDV Workshop (which I believe is GRIB1), the thermal wind vectors plot fine.
I suspect there is some issue specifically related to GRIB2 format here ... Thanks for looking into this! --Kevin _____________________________________________ Kevin Tyle, Systems Administrator Dept. of Atmospheric & Environmental Sciences University at Albany Earth Science 235, 1400 Washington Avenue Albany, NY 12222 Email: ktyle@xxxxxxxxxx Phone: 518-442-4578 _____________________________________________
