Does anyone know if it is possible to access the raw data that is
used for the winds aloft plots on aviationweather.gov?

The NWS has a lot of data available via FTP (see
http://www.nws.noaa.gov/tg/dataprod.html ) but from a quick look I
don't _think_ the winds aloft data is included.

The NWS also has wind profilers - basically radars that sit on the
ground and point straight up all the time. These give observed winds,
not forecast winds. Also, they don't cover the whole country, but
might be useful if you happen to be near one of the profilers. Plots
of the profiler data are available at
http://www.profiler.noaa.gov/npn/profiler.jsp .

It is quite possible that they might be interpolating in space and
time, but I would like to know if there is another data set that I
am not aware of.

In the past, I have gotten timely responses from the NWS by using the
"contact us" email links that are usually on their pages.
