Dave and Dennis,<br>
<br>
The plot using "stereographic" for <br>
"polar stereographic map projection" data is perfect now. <br>
<br>

ftp://ftp.caps.ou.edu/users/yli/oban/oban02.pdf<br>
<br>
Here is a summary.<br>
<br>
My regional data obtained from "<span style="color: rgb(0, 0, 255);">polar stereographic</span><br style="color: rgb(0, 0, 255);">
<span style="color: rgb(0, 0, 255);">map projection</span>" can be plotted by NCL "<span style="color: rgb(0, 0, 255);">stereographic</span>".
<br>
However, "<span style="color: rgb(0, 0, 255);">mpCenterLatF = 90.</span> " must be used because<br>
polar projection is centered at "<span style="color: rgb(0, 0, 255);">north pole</span>".
<br>
<br>
Thanks.<br>

Sorry Yongzuo, I meant to say set mpCenterLatF to 90.<br>

Hi Yongzuo,<br>
It's because the map projection parameters you are setting do not match the projection of the data. Try setting mpCenterLonF to 90.<br>

Hi,<br>
<br>
<br>
<br>
I am using ftp://ftp.caps.ou.edu/users/yli/oban/oban02.ncl<br>
<br>
to plot ftp://ftp.caps.ou.edu/users/yli/oban/oban02.pdf<br>
<br>
<br>
<br>
The area over right edge is empty. All other plots of map <br>
<br>
and contours are absolutely correct and match each other<br>
<br>
exactly. All data are under the same directory <br>
<br>
ftp://ftp.caps.ou.edu/users/yli/oban/<br>
<br>
<br>
<br>
Any help is appreciated !<br>
<br>
<br>
