Due to historical reason analysis date and time values are currently encoded incorrectly in MACC_GFAS file and directory names so dates :
- Date in directory
...
- name does not match
...
- date in file name.
- Step value is encoded incorrectly in current GRIB files.
Here is

This file contains 00:00 - 23:59 analysis from the 7 12 Sep.
To make validity of the analysis more obvious fix the incorrect directory and file names, we've created a new parallel stream called CAMS_GFAS with . The new stream contains exactly the same GFAS data but using uses a more consistent logical file naming convention.
The same data from the above example is available in this file in the new stream under new file name:

The data will become available in the new stream at the same time as in the existing MACC_GFAS stream until July 2018, when MACC_GFAS stream will be discontinued out.
