 Am new to GRAD. What I need is to plot the ocean current's U,V Components
on Google Map. NetCDF file contains the data.
NetCDF files will be downloaded from URL
*http://nomads.ncep.noaa.gov/pub/data/nccf/com/rtofs/prod/
<http://nomads.ncep.noaa.gov/pub/data/nccf/com/rtofs/prod/rtofs.20131129/>*

Can anyone suggest me how to plot its U,V components on grad and export it
to image and does this source provide global data for current?? .
The strength of U,V current will determine the width of the Arrow. I am
attaching the Sample image got from client (for the reference of arrows I
need).
*What I did so far is :*

sdfopen C:\WeatherGribFiles\rtofs_et_WPAb_3dz_f06_6hrly_reg1.nc

Can any one help me out or share if have any working example to draw u,v
components of current and its strength on basis of components vale !!!!!!
