<div dir="ltr"> Am new to GRAD. What I need is to plot the ocean current's U,V Components on Google Map.

<div>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).</div><div><b>What I did so far is :</b><br><br><div>sdfopen C:\WeatherGribFiles\rtofs_et_WPAb_3dz_f06_6hrly_reg1.nc</div>
