Hi Jim,<br>
<br>
It's the sample Himawari-8 data on the BOM site:

Cheers, Mike<br>

Hi Mike,<br>
<br>
From where are you getting these files? The x,y coordinates are
in meters and not degrees. Without specifying the<br>
lat/lon it looks like you are getting the full disk image. The
netcdf files at JMA appear to be in lat/lon<br>
<a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://www.data.jma.go.jp/mscweb/en/himawari89/space_segment/sample_netcdf.html" style="color: blue; text-decoration: underline;">http://www.data.jma.go.jp/mscweb/en/himawari89/space_segment/sample_netcdf.html</a>,
but as yet they only<br>
seem to have the Japan-centric images.<br>

lat/lon region, but when I specify any lat/lon region I just
get a chart with a red output. When I don’t specify any
lat/lon output at all, I get a bizzare chart (I’m guessing
because it’s using x and y coordinates instead of lat/lon?)
Is there any way to correctly get this to display in grads
at all?<o:p></o:p></p>
