<div dir="ltr">Hi Gerard,<div><br></div><div>In NCL versions >= 6.2.1, there is an undocumented interface to the Proj4 cartographic projections library. Its function signature is:</div><div><br></div><div> <span style="font-family:menlo;font-size:14px;background-color:rgb(254,250,207)">transform_coordinate(SrcProjStr, DestProjStr, x[], y[], z[])</span></div><div><span style="font-family:menlo;font-size:14px;background-color:rgb(254,250,207)"><br></span></div><div><span style="background-color:rgb(255,255,255)"><font face="arial, helvetica, sans-serif">where the two strings are the Proj4 projection strings, and x/y/z are arrays of type double. The transformed results are returned in the arrays, overwriting the original values.</font></span></div><div><span style="background-color:rgb(255,255,255)"><font face="arial, helvetica, sans-serif"><br></font></span></div><div><font face="arial, helvetica, sans-serif">If you are unfamiliar with proj4 strings, send me the details of your projection (standard parallels, center of projection, etc.) and I will send back appropriate strings.</font></div><div><font face="arial, helvetica, sans-serif"><br></font></div><div><font face="arial, helvetica, sans-serif">Hope that helps...</font></div><div><font face="arial, helvetica, sans-serif">Rick</font></div><div><font face="arial, helvetica, sans-serif"><br></font></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Oct 27, 2016 at 8:02 AM, G.

<p>NCL support</p>
<p>I am writing python code to retrieve data from WRF results.</p>
<p> For this purpose I would like to convert WGS84 lat/lon
coordinates to the Lambert coordinates used by WRF.</p>
<p>To test my code for other scripts I have been using NCL.</p>
<p>Unfortunately, so far I have not been able to output Lambert
coordinates from NCL.</p>
<p>Please can you suggest how I can print Lambert coordinates after
feeding NCL with lat/lon coordinates.</p>
<p>Kind regards, Gerard<br>
