<div dir="ltr"><div>XLAT_M, XLONG_M don't actually exist in a typical WRF output file, it's just XLAT and XLONG for the mass grid (XLAT_U for the u-staggering, XLAT_V for the v-staggering). However, the metgrid output 'met_em' files use XLAT_M and XLONG_M for the mass grid, and some of the WRF algorithms fall back to looking for XLAT_M when it can't find XLAT, thinking it might be a 'met_em' file instead. This is probably why we're seeing the missing XLAT_M error. In any case, combining the two files together should fix it, as long as they didn't remove anything else that the WRF algorithms are looking for.<br></div><div><br></div><div>Hope this helps,</div><div><br></div><div>Bill</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Oct 26, 2016 at 5:04 PM, 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"><div dir="ltr"><div><div><div>Hello,<br><br></div>Actually, I'm not sure how the script you sent ever got to the point where it was doing contouring.

Hi NCL talk,
<div><br>
</div>
<div>I am using the script WRF_pcp_1.ncl which contours precipitation and terrain and overlays them using wrf_map_overlays. I am running NCL V 6.3.</div>
<div><br>
</div>
<div>Unfortunately I receive the following fatal errors:</div>
<div>
<div style="margin:0px;font-size:11px;font-family:Menlo">fatal:ContourPlotPreDraw: ARSCAM/ARPRAM - ALGORITHM FAILURE</div>
<div style="margin:0px;font-size:11px;font-family:Menlo">fatal:ContourPlotDraw: draw error</div>
<div style="margin:0px;font-size:11px;font-family:Menlo">fatal:PlotManagerPreDraw: error in plot pre-draw</div>
<div style="margin:0px;font-size:11px;font-family:Menlo">fatal:_NhlPlotManagerDraw: PreDraw error</div>
</div>
<div style="margin:0px;font-size:11px"><br>
</div>
<div style="margin:0px">I’ve also tried using “RasterFill” instead of “AreaFill”, as recommended browsing through previous questions, however topography was not being contoured properly. </div>
<div style="margin:0px"><br>
</div>
<div style="margin:0px">I have attached my script. The two files listed when using systemfunc include one file with the WRF 2d data and another with the WRF constants (XLAT, XLONG, etc).</div>
<div style="margin:0px"><br>
</div>
<div style="margin:0px">Any suggestions please?</div>
