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>
