    1718NetCDF can't deal with files > 2GB except on cyclone.
    1819It is possible to write netCDF files that exceed 2 GB on platforms that have "Large File Support" (LFS). Such files are platform-independent to other LFS platforms, but trying to open them on an older platform without LFS yields a "file too large" error.
     20On cyclone I observed the error
     21Time = 20820.0000, delta t in [0.33171153, 0.99331961], steps=39 (39)
     22Boundary values at time 20820.0000:
