[IDV #TSZ-747127]: loading and interpolating point (station) data in IDV

Hi Youssef,

The IDV will read these data just fine. You need to correctly load the CSV data.
We provide a movie on how to load in CSV data into the IDV.

See the attached image for how to define CSV data.

I do not know the units of rain so I just guessed millimeters. See the attached
image for the plot of these data.

Best,

Unidata IDV Support
