Salut Thomas,
Nothing better if i request with other values of longitude (260 or -100).
With 110/-100 the response of the subset service is
NetCDF Subset Service exception handled : Invalid bbox. Bounding Box must have
east > west; if crossing 180 meridian, use east boundary > 180
I think Don Murray gave us a clear answer.
Thanks,
Tony

Objet : Re: [thredds] NCSS : request that subset data across 180° longitude
The TDS does not support subsets across the grid boundary. But it should.
