<div dir="ltr">Hello,<div>I am having trouble calculating the US county area averages using gridded CONUS data and US county shape file data. The county polyline overlay works, but I cannot get the county area average function to work with my data.</div>
<div>Following the example script </div><div><a href="http://www.ncl.ucar.edu/Applications/Scripts/shapefiles_13.ncl" target="_blank">www.ncl.ucar.edu/Applications/Scripts/shapefiles_13.ncl</a></div><div>I am getting the following error:</div>
<div><br></div><div>fatal: Subscript out of range, error in subscript #0</div><div>fatal: An error occurred reading skip_check</div><div><br></div><div>;The CONUS data is land only for the coterminous US:</div><div><div>
<br></div><div>hf1 = addfile("<a href="http://conus.nc" target="_blank">conus.nc</a>","r")</div><div>data = hf1->tmaxhist(:,:) ; ((/nlat,nlon/),float)</div></div><div>lat = hf1->lat</div>
<div>lon = hf1->lon</div>
<div><br></div><div>; The attributes of data and lat/lon are as follows:</div><div>; nlat = 222</div>
<div>; nlon = 462</div><div>; minlat/maxlat = 25.1875/52.8125</div><div>; minlon/maxlon = 235.312/292.938</div>
<div>; lat@units = "degrees_north"</div><div>; lon@units = "degrees_east"</div><div><br></div><div><br></div><div>Any help would be much appreciated. Thank you.</div><div>-- <br><div dir="ltr"><div style="font-family:arial;font-size:small">
