I’m looking at using lower packing options to save space with some output that’s getting unmanageably large. (8 runs of 1.5km res large domain 40 day simulations). I’ve already switched to netcdf. Previously I’ve used packing option 7 which the help info suggests is suitable for convective scale output, options 2 for example for climate output gives data to 3.s.f. and produces files at like half the size. Can anyone verify if this is sensible? I’ve read the umdps and I think this should be fine although I can’t tell if this is commonly done.
My other option is to compress all the files further, but I think the space saving is less and potentially adds a big bottleneck to the runs.
