Robert,

This looks like you could create a grid format file with U a V at
the various pressure levels assuming you have more points than just the
subset you have below (looking at your LON of 2.5 degree spacing).

If the area is relatively small, than a script to parse the data into a
file for importing with GDEDIT would be the easiset way. If the data
base werelarge, then it might be easier to go from a program to read the
data use the gemlib calls to create the grid file and output the data.
