I am working with NEXRAD radar data, and I am trying to plot the U and V wind velocity for each point on a grid. There is a channel in the data called "Velocity" described as "A measure of the radial component of the wind either toward the radar (negative values) or away from the radar (positive values)"

I am using the Py-Art library to create a grid of this velocity data. Now that I have a grid of the velocity (m/s) and angle (theta) for each point on my grid, can I simply calculate the U and V velocties with sin and cos?

  • $\begingroup$ Keep in mind that because it only gives you towards/away, you are missing a component of the two-dimensional field. For example, due west of the radar... you have no north\south (v) data known at all. Looks like papers like this one offer some help, based upon changes over time, but indeed single doppler has some shortcomings. $\endgroup$
