Newsletter No 1

May 2015

UERRA has been running for a bit over one year now. The collaborative EU FP7 Project has 12 partners and after holding the first General Assembly/Kick-off meeting in Exeter last year in March, the 2nd General Assembly was held in Tortosa, Spain at the end of January this year.

This newsletter is also available as a pdf file.

UERRA General Assembly and Consortium meeting 2015

The first year of the project saw the setting up of the ensemble reanalysis systems to be used in the Project. Some of these systems were developed in the pre-cursor FP7 EURO4M project although in UERRA, there are also new systems or significant developments of the previous systems.

Over 5 million historical observations have been rescued and are processed

The availability of homogeneous observations is essential for climate reanalyses and the Data resque and development efforts from EURO4M have continues in UERRA. The emphasis is now on sub-daily time scales and post 1961 data, as far as possible.

HARMONIE Upper air 3-dimensional reanalyses two physics ensemble

SMHI is running atmospheric 3-dimensional data assimilation. There are two atmospheric physics options and different downscaling and surface model options which are used to create ensembles. These systems have been run in reanalysis mode for quite some time.

Near surface ensemble reanalysis

Météo-France 2 dimensional near-surface assimilations coupled with the SMHI HARMONIE 3-dimensional reanalyses.

Large ensemble reanalysis systems being developed at the Met Office

The Met Office is developing the most expansive computationally demanding ensemble assimilation system which is described more here and a report is available about the design.

The COSMO Ensemble reanalysis developing at University of Bonn

The University of Bonn has developed an Ensemble nudging scheme within the COSMO modelling system from DWD. It is a first step to combine a hybrid LETKF (Localised Ensemble Transform Filter) with the nudging scheme.

24 hour precipitation in the control

Data services and evaluation procedures being developed

Evaluation procedures have been defined during and after the WP3 Workshop in Offenbach last summer. In connection with this access to the previous and current reanalysis through ECMWF MARS has been extensively discussed, defined and some products provided.

Use oriented products and climate information for the public and stake holders

User oriented products to stakeholders and the public continue to be produced. There are also other downstream models driven by reanalyses, in particular hycrological models and where there are special observations.

User Workshop and General Assembly early 2016

There will be two user workshops in UERRA; the first one will establish early contacts with users or potential users of reanalysis products. It will be in connection with the UERRA GA 1-3 February 2016 (3-4 February).

Getting prepared for Copernicus Climate Change Services

UERRA is developing a pre-operational regional C3S (Copernicus Climate Change Service) in several areas. The different Work packages in UERRA naturally aim for these areas and UERRA partners are expected to be active in the tendering process.

Observation collection and processing: Call and start now in 2015.

Regional Climate Reanalyses: Call in late 2016 and start in 2017.

Evaluation and quality control: Proof-of-concept call and start now in 2015.
