Hi all,
I have been trying to plot horizontal current data from the RTOFS dods/opendap site but, it does not seem right.
For example if I open this site http://nomads.ncep.noaa.gov:9090/dods/ofs/ofs20100818/daily/rtofs_native_024_atl through sdfopen, and use the following commands:

ga->set lev 3
ga-> d mag(2*uogrddsl,2*vogrddsl)
Contouring: 1 to 7 interval 1
ga-> cbarn
ga-> set gxout vector
ga-> set cthick 4
cthick = 4
ga-> d skip(2*uogrddsl,3,3);2*vogrddsl

The plotted vectors don't look right. It seems more like a radial outward component than a horizontal current direction. The plotted vectors don't correlate with real life data.

Did I overlook something ?

Thanks
Marck
