Bob, to clarify, I can create an image, but the problem is that like you mentioned, I’m not sure of a way to overlay the basemap.

</div>
<div>Jeff, </div>
<div>That seems like what I need to do. Could you provide an example of a control file that might do the trick? </div>

<p style="margin-top:0;margin-bottom:0">Hi everyone,</p>
<p style="margin-top:0;margin-bottom:0">I'm looking for a way to plot some satellite data in GrADS. I've found a source for GOES-16 netcdf data, but its format is not compatible as shown below; the lat and lon are set to the number of grid points in the file,
not the lat/lon extent of the file:</p>

</div>
<div>I've seen this issue pop up previously on the forum, but there was no good answer I could make sense of. I'm hoping someone could share some code with me to help resolve the issue, or better yet point me to a source of netcdf's that can be read in via
the sdfopen command. <br>
