The ERA5 datasets and variables have been prioritised based on the needs of the ARC LIEF recipients supporting this collection and the broader Australian research community. NCI replicates all the available quality controlled data and in most cases, this equates to coverage from 1979* - present (minus 3 months). The 1950 back extension (once released by ECMWF) will be replicated in the priority order specified in the download queues (from 1979 to 1950). Unless explicitly noted, all datasets are replicated for the full global domain. 

The Replication Plan displayed below summarises the priority datasets and availability at NCI (or anticipated completion date) and will be updated as each priority group commences or has completed. 

Sections in this page are broken into the following topics:

* ERA5-Land coverage begins from 1981.

Note

Parameters within the NCI collection are from the model analyses with the exception of a number of forecast parameters, e.g. mean rates and accumulations, that are only available from forecasts. Please see the ECMWF ERA5 Data Documentation for more information.

Primary Download Queue

The following datasets are available through ECMWF's Climate Data Store (CDS) and will be replicated at NCI in the following order listed in the table below. Please note that the NCI replica does not include the high resolution ERA5 Table 3 parameters. The mean rates in Table 4 can be used to convert to the Table 3 equivalents using the information in the footnote of Table 4. 

Info
titleERA5 Preliminary Back Extension Data

Replication of the preliminary 1950 back extension has partially completed. Preliminary data can be found under the 'era5-preliminary' sub-folder of the collection, e.g., 

/g/data/rt52/era5-preliminary

An updated version of the back extension has been released from 1959 to 1978 which is being downloaded to the main collection area.  The preliminary data from 1950 to 1958 remains in the era5-preliminary directory.

The following datasets are all available through ECMWF's MARS tape system and will be replicated at NCI in the following order below. Please note this tape system is slower and more variable and as such the estimated time frames will be less precise.
