[IDV #MUH-833217]: Problem using formulas in IDV (Latest version)

Alfred,

Would it be possible to upload the RAP hybrid analysis files to

http://motherlode.ucar.edu/repository/alias/idvupload

Displaying wind speed should be a straight forward operation. In the IDV field
selector tab of the Dashboard you should be able to find wind speed under 3D
Grid > Momentum > Derived > Speed from U and V.

If not it is possible to that you have to set up a parameter alias.

Best,

Unidata IDV Support
