This page keeps track of the official releases of the GloFAS system, including its components. GloFAS is versioned with a three-number system X.Y.Z responding to Major.Minor.Patch updates of the system. We only communicate major and minor updates in this page.
Current operational system and data availability
|Latest operational GloFAS release|
GloFAS guidelines for versioning
|Major||Significant upgrades that involve changes to the hydrological modelling chain (e.g. rainfall-runoff and routing)||Calibration, major changes to the physics. Can also be a major technical change.||Communicated via the GloFAS website (www.globalfloods.eu) 4 weeks before implementation; associated with a period of testing for the users|
Major technical change or minor change in the output
|New layer, new product, change of format, update of thresholds, upgrade real-time ECMWF IFS data input, update reference climatology, update forecast reruns||Communicated via the GloFAS website (www.globalfloods.eu) 1 week before implementation|
|Patch||Bugfix or update of information in the system. Might affect post-processed layers, but have no impact on the model output||Bugfix, update of layer names, minor technical updates||Are immediately released into production|
Each major or minor release comprises data associated with
- the operational real-time forecasts (30-day and seasonal)
- the hydrological reanalysis
- the discharge forecast reruns (30-day and seasonal)
- the discharge thresholds (30-day and seasonal)
The GloFAS versioning system started with the operational release of GloFAS in 2018. The GloFAS versions prior to v1.0 are not versioned.

*) This number is for MARS archiving. Each new version with a climatology will be given a new number.
**) This minor upgrade to v2.2 does not include any modelling changes and therefore data is the same as v2.1, hence remains GloFAS internal number = 003
***) From mid-September 2022 GloFAS version 2.1 is decommissioned and no longer produces new data. Data previously produced by this version of GloFAS will remain available through the CDS. This does not affect the operational GloFAS service.
