We have recently switchws our data format from HDF4 to HDF5 (via NETCDF4).
The filesize has increased by nearly a factor of 5:
HDF4: 170873864 S20070012007004.L3b_4D_ST93.main
HDF5: 905223847 S20070012007004.L3b_4D_ST97.main
Using compressions helps somewhat, the factor goes to 2, however is there
a simple explanation why HDF5 files are significantly larger than HDF4
files when essentially storing the same information?
