Hi Louis-Philippe,
With much kind respect, the test case that you provided was not very
simple, so I had to spend much effort to create a tiny test case, that
contains one of your NetCDF files, and a small mapfile that simply
reprojects the file into EPSG:3857 (without WMS etc.). The small test
case contains a single shp2img command to replicate the issue (in a file
'commands.txt') which you can download at
https://gatewaygeomatics.com/dl/netcdf-2020-06-26.zip
The issue that you report, of a sliver (no data) in the map when
reprojecting to 3857, is visible in the resulting map images in the live
demo at:
https://demo.gatewaygeomatics.com/cgi-bin/mapserv?MAP=/home/apps/netcdf/2020-06-26/netcdf-test.map&MODE=browse&TEMPLATE=openlayers&LAYERS=all
(this server is running MapServer-master)
This should be filed as a new ticket at
https://github.com/mapserver/mapserver/issues and point to this test
zipfile.
Have a nice weekend,
-jeff

The issue is that when I try to visualize (via WMS) a layer with a
NetCDF data file with longitude from 0° to 360° in EPSG:3857, there is a
sliver around longitude 0° where no data is displayed.
