title15-04-2021 ECCC data resolution change

The horizontal resolution of the ECCC contribution to TIGGE has been increased from 1.0 to 0.25 degree since 12Z  Also the GRIB 2 packing has been changed to simple instead of complex one (that will generally  increase file sizes but also significantly reduce time needed to process such data). All TIGGE data from all participating models should be encoded now using simple GRIB 2 packing.

Further details can be found in the page Models.
