<div dir="ltr"><div>You can check your own control file to verify this (because I can't see it here), but I suspect the problem is a mismatch between the expected field names in the script and what your data file actually has present. You will have to change the values of 'u', 'v', 'tc', and 'td' most likely, to whatever the actual field names are in your data set. And if you don't have 3D dewpoint specifically, you'll have to calculate it manually before running the script.</div><div><br></div><div>Jeff Duda<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Apr 5, 2020 at 12:23 AM Mohanmurali Krishna <<a href="mailto:invenmmk@gmail.com">invenmmk@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Dear all I m getting this kind of error when I have tried to plot Skew-T (with the attached script)<div><br></div><div>Data Request Error: Invalid grid coordinates<br> World coordinates convert to non-integer grid coordinates<br> Variable = u Dimension = 2<br>Operation Error: Error from sqrt function<br> Error ocurred at column 2<br>DEFINE error: Invalid expression.<br>Data Request Error: Invalid grid coordinates<br> World coordinates convert to non-integer grid coordinates<br> Variable = u Dimension = 2<br>Operation Error: Error from atan2 function<br> Error ocurred at column 2<br>DEFINE error: Invalid expression.<br>Data Request Error: Invalid grid coordinates<br> World coordinates convert to non-integer grid coordinates<br> Variable = tc Dimension = 2<br> Error ocurred at column 2<br>ga-><br>Data Request Error: Invalid grid coordinates<br> World coordinates convert to non-integer grid coordinates<br> Variable = td Dimension = 2<br> Error ocurred at column 2<br>DEFINE error: Invalid expression.<br>Drawing temperature sounding.<br>Syntax Error: Invalid Operand<br> 'tempx' not a variable or function name<br> Error ocurred at column 1<br>DISPLAY error: Invalid expression<br> Expression = tempx<br>Drawing dewpoint sounding.<br>Syntax Error: Invalid Operand<br> 'dewpx' not a variable or function name<br> Error ocurred at column 1<br>DISPLAY error: Invalid expression<br> Expression = dewpx<br>Calculating precipitable water.<br>Data Request Error: Invalid grid coordinates<br> World coordinates convert to non-integer grid coordinates<br> Variable = tc Dimension = 2<br> Error ocurred at column 1<br>DISPLAY error: Invalid expression<br> Expression = tc(lev=550)<br>Non-numeric args to numeric operation<br> Error occurred on line 2457<br> In file <a href="http://skew.gs" target="_blank">skew.gs</a><br> Error occurred on line 2235<br> In file <a href="http://skew.gs" target="_blank">skew.gs</a><br> Error occurred on line 2080<br> In file <a href="http://skew.gs" target="_blank">skew.gs</a><br> Error occurred on line 1240<br> In file <a href="http://skew.gs" target="_blank">skew.gs</a><br> Error occurred on line 68<br> In file <a href="http://skew.gs" target="_blank">skew.gs</a><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, 18 Mar 2020 at 21:11, Jeff Duda <<a href="mailto:jeffduda319@gmail.com" target="_blank">jeffduda319@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Please provide more detail as to the description of the failures you are seeing.</div><div><br></div><div>Jeff Duda<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Mar 18, 2020 at 3:36 AM Mohanmurali Krishna <<a href="mailto:invenmmk@gmail.com" target="_blank">invenmmk@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Dear all<div><br></div><div>I have a doubt regarding how to plot Skew-T plot from the '.ctl' file after converting from WRF output.
