@cesarchirosa Hi, here is the link to georeferenced NetCDF file. It covers the same area as the animation (the animation was created from this file). https://goo.gl/x4uC2m
The color scale of the animation is described in the bottom part. In the online viewer it is probably covered by controls of the player, but if you download the animation and play it in some other video player, you should see the color legend.
The description of the legend is a bit mathematic mess (filled by the Panoply software), but it exactly means wind speed in meters per second.
We would be happy if this information is useful for your work and can help you to protect Amazon rainforest!
