Hai <font size="2">Anuradha,<br><br>I dont know whether </font><font size="2">spherical map projection is available but you can use Robinson projection which is similar for this purpose. The easy method is to use <a href="http://map.gs">map.gs</a> form grads script library<br>
<br><a href="http://grads.iges.org/grads/gadoc/library.html"> http://grads.iges.org/grads/gadoc/library.html</a><br><br>copy it to grads library or you data folder. then type "map". There you have several options in which you select "robinson". Then plot the varible. It will be like the attached figure. Also i am attaching a copy of the <a href="http://map.gs">map.gs</a> file<br>

<div bgcolor="#ffffff"><font size="2">Dear Users,<br>Can anybody suggest how to plot a global data in spherical map projection in grads<br>I attached a example plot ( made in ferret),<br>Same kind of figure can be plotted in grads?<br>
<br>I found these options, but I did not find a right option for my requirement ( figure attached)<br></font><p>
<font size="2"><code>set mproj <i>proj</i></code></font></p><p><font size="2">
Sets current map projection. Options for <code><i>proj</i></code> are:
</font></p><p> </p><ul><font size="2"><code>latlon </code>
Lat/lon projection with aspect ratio maintained (default) <br><code>scaled </code>
Lat/lon aspect ratio is not maintained; plot fills entire plotting area<br><code>nps </code>
North polar stereographic <br><code>sps </code>
South polar stereographic <br><code>lambert </code>
Lambert conformal conic projection<br><code>mollweide </code>
Mollweide projection<br><code>orthogr </code>
Orthographic projection<br><code>robinson </code>
Robinson projection, requires <code>set lon -180 180, set lat -90 90</code><br><code>off </code>
No map is drawn; axis labels are not interpreted as lat/lon </font><br></ul>
