AEC is an implementation of CCSDS compression using libaec.
CCSDS stands for Consultative Committee for Space Data Systems and is a WMO standard for lossless data compression (Data representation template 5.42)

Note: This is only available in GRIB edition 2

To encode with this packing type:

% grib_set -r -s packingType=grid_ccsds in.grib2 out.grib2

This is relatively fast with a good compression ratio.

When building ecCodes, make sure you install libaec and enable this option via the cmake option -DENABLE_AEC=ON.
