<p class="MsoNormal">Hello,<o:p></o:p></p>
<div>
<p class="MsoNormal">if you're using NCL to project the data onto lat-lon (mpres@tfDoNDCOverlay= False) you should be able to zoom-in into the data by defining the corners of the projection. if that does not work it means there is something wrong in the script
or the way the variables are defined.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Furthermore, try to assign lon2d and lat2d as attributes to the variable that you're plotting and not to explicitly define them as sfXarray and sfYArray so that NCL knows how to plot your variable. <o:p></o:p></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">Was just curious if there’s a way to create a zoom map of regional gridded data. For example, I have a regional curvilinear model grid with 2d lat/longs that takes a stereographic
projection. To map the full regional extent, I use the following set of resources. However, in order to plot a zoomed in area for this example, mp Min/Max Lat/LonF settings do not work and, I believe, sf Y/X End/Start SubsetV do not work either. Is the best
approach to subset the data and the coordinates to new corners first using getind_latlon2d? And if I use this approach, does the new subset grid retain the original projection given that it will have new corners?<o:p></o:p></span></p>
