File format conversion

POP now supports direct netCDF output and such output is recommended unless it creates a performance bottleneck for large grids. In cases where binary output is required, conversion to netCDF can be achieved off-line through a utility called bin2nc, which is available from LANL.

CESM1 Notes

CESM1 POP2 supports 64-bit offset netCDF output, which allows larger file sizes than the 2Mb supported by the "classic" netCDF format. To address performance issues with large sizes, the CESM1 POP2 code uses the PIO library to write netCDF output files in parallel. See the PIO library documentation for more details.
