<div dir="ltr"><div>Thanks a lot for your suggestions. I have modified my script as per your suggestions, but instead of overlaying plot am getting a single plot, and it is taking a lot of time for only two files (for testing purpose I am doing with 2 files out of 14) not able to understand where am I making the mistake. The plot and the modified script is attached herewith.<br><br></div><div>Thanks,<br></div>Ipsita<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Nov 14, 2015 at 12:50 AM, Dennis Shea <span dir="ltr"><<a href="mailto:shea@ucar.edu" target="_blank">shea@ucar.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> diri = "./" ; input directory<br>

Why are you doing this<br>
<br>
delete(fn)<br>
delete(f)<br>
delete(vnlon)<br>
delete(ulon)<br>
delete(vnlat)<br>
delete(ulat)<br>
delete(vnrr)<br>
delete(urr)<br>
delete(rr)<br>
delete(dims)<br>
delete(nlon)<br>
delete(nlat)<br>
<br>
If the variables are the same size, they will overwrite the previous values.<br>
<br>
If they are not the same size:<br>
<br>
delete( [/ fn, f, vnlon, ulon,......... /] ) delete multiple<br>
variable in one command<br>
<br>
or, use NCL's := reassignment syntax<br>
<br>
urr := f->$vnrr$ ; if urr exists; delete and write with new values<br>
