This page has been revised as of to introduce the new naming convention for AIFS data available via dissemination. AIFS data was released via dissemination in April 2024. |
The following dissemination filename convention is used for the transmission of ECMWF dissemination products:
ccSMMDDHHIImmddhhiiE where:
S | Description | Stream & Type (where applicable) |
---|---|---|
A | HRES Weather Parameter products (10-day) | stream=oper, type=wp |
B | ENS Weather Parameter products (15-day) | stream=enfo, type=wp |
C | Tropical Cyclone high resolution trajectory forecast products (HRES) (10-day) | stream=oper/scda, type=tf |
D | High resolution forecast products - atmospheric data (HRES) (10-day) | stream=oper (also scda for 06/18 if requested) |
E | Ensemble forecast products- atmospheric data (ENS) (15-day) | stream=enfo (00/06/12/18) |
F | Extended range forecast products - atmospheric data (ENS-extended) (46-day) | stream=eefo (was enfo) |
G | Ensemble forecast products - high-frequency wave data (ENS-WAM) (15-day) | stream=waef |
H | Extended range re-forecast products - atmospheric data (ENS-extended) (46-day) | stream=eefh/eehs (was enfh/efhs) |
I | Ensemble re-forecast products - atmospheric data (ENS) (15-day) | stream=enfh/efhs (new) |
J | Ensemble re-forecast products - wave data (ENS) (15-day) | stream=enwh/wehs (new) |
L | Seasonal forecasting system products - atmospheric data (SEAS) | stream=mmsm/mmsf/mmsa |
N | Seasonal forecasting system products - wave data (SEAS-WAM) | stream=wasf |
P | High resolution forecast - wave data (HRES-WAM) (10-day) | stream=wave (00/12) |
Q | High resolution forecast - high-frequency wave data (HRES-WAM) (10-day) | stream=scwv (06/18) |
S | High resolution forecast - high-frequency atmospheric data (HRES) (10-day) | stream=scda |
T | Tropical Cyclone ensemble trajectory forecast products (ENS) | stream=enfo, type=tf |
U | Ensemble forecast post-processed products - wave data (e.g. ensemble means, extreme forecast indices) | stream=waef, type=em/efi/sot/ep |
V | Extended range forecast products - wave data (ENS-WAM-extended) (46-day) | stream=weef (was waef) |
W | Ensemble forecast products - wave data (ENS-WAM) (15-day) | stream=waef |
X | Ensemble forecast products - high-frequency atmospheric data (ENS) (15-day) | stream=enfo |
Y | Ensemble forecast post-processed products - atmospheric data (e.g. ensemble means, extreme forecast indices) | stream=enfo, type=em/efi/sot/ep |
Z | Extended range re-forecast products - wave data | stream=weeh/wees (was enwh/wehs) |
Most products are encoded in WMO FM-92 GRIB edition 1, unless otherwise specified in our Catalogue of Real-time products

Naming - AIFS via disseminationTaking into account user feedback, ECMWF has chosen to implement a new naming convention for the AIFS data via dissemination.
The composition of the file will be comprised of MARS standard information such as class, stream, type but combined with unique user identifiers such as Destination name and Feed name:
Therefore, an example filename would be:
