FINECAST VDAS Wind Field Model Output
https://data.eol.ucar.edu/dataset/534.056

Summary
VDRAS, a 4DVar Four-Dimensional Variational data assimilation system, was used
to generate 3-dimensional wind fields for the SNOWIE IOPs. The 300 m WRF
simulations were used as input data. Radar data from DOW6 and DOW7,
operational and experimental SNOWIE-sounding data, and surface observations
were assimilated. The output fields have a 1 km x 1 km x 0.2 km resolution and
are centered around the SNOWIE domain. Note that this is a large dataset. You
may be required to limit the number of files that you order based on the total
size of your order.
