<div>You have sent the same question before, The reason for no reply is that the question is rather vague.<br>
<br>
</div>
[1] You can read the variable and use the two-dimensional coordinates latitude(y,x) ; longitude (y,x) to plot vis:<br>
<br>
<br>
</div>
f = addfile("<a href="http://foo.nc">foo.nc</a>", "r")<br>
</div>
x = f->X ; :(time,lev,y,x)<br>
</div>
x@lat2d = f->latitude ; (y,x)<br>
</div>
x@lon2d = f->longitude<br>
<br>
<pre> wks = gsn_open_wks("png","polar") ; send graphics to PNG file
res = True ; plot mods desired
res@gsnPolar = "NH" ; specify the hemisphere<br> <br></pre>
<pre> nt = 0 <br> lev = 10 <br> plot = gsn_csm_contour_map_polar(wks,x(nt,klev,:,:),res)<br><br></pre>
<pre>or, maybe<br></pre>
<pre> plev = 500 ; natural coordinate<br> plot = gsn_csm_contour_map_polar(wks,x(nt,{plev},:,:),res) <br><br>===<br></pre>
<pre>[2]<br>If you want the polar data regridded then see:<br> <a href="http://www.ncl.ucar.edu/Applications/ESMF.shtml">http://www.ncl.ucar.edu/Applications/ESMF.shtml</a><br><br></pre>
<pre>Your source grid would be classified as 'curvilinear'.<br></pre>
<pre>Your resulting file would ve 'rectilinear'<br><br></pre>
<pre>Good luck<br></pre>

<p>Dear All</p>
<p><br>
</p>
<p>How to convert the stereographic projection x-y coordinates to lat lon grids? I have the 2d lat lon coordinates but the variable is in x-y coordinates e.g
</p>
<p><br>
</p>
<p>temp(time,depth,y,x).</p>
<p><br>
</p>
<p>and latitude(y,x) ; longitude (y,x)</p>
<p><br>
</p>
<p>Is it poosible to get temp(time,depth,latitude,<wbr>longitude) from this information?</p>
<p><br>
</p>
<p>Thanks<br>
</p>
