Several interesting Scientific and Technical Reports have been produced in UERRA recently. Now that we have many results after over three years of Research, Development and Production. As examples we can mention:

a) User Synthesis of the Reanalyses

b) User Guidance

c) Nudging Ensemble Reanalysis diagnostics documentation and report (University of Bonn)

d) Uncertainties in Regional Reanalyses - Final Report from the Met Office

e) Scientific report of the assessment of the reanalyses

f) Reanalysis Uncertainty evaluation

g) HARMONIE Reanalysis report

h) the Surface MESCAN ensemble analysis report

i) the Ensemble 4D-VAR reanalysis documentation and report

j) the description and demonstration of publishing one UERRA dataset on an ESGF node and

k) the Development of more comprehensive uncertainty estimations in the observation gridding (E-OBS) including an improved method for interpolation.

j) UERRA Final Report

Also the Observation rescue and development (QC) in UERRA is complete and data sets are available at URV and several international data centres as documented in the reports of the data sets and of the data repositories where data have been sent to.

UERRA had its 5th General Assembly in Tarragona. (28-29 November, both full days). Please see the GA 5 page for further information. Please find the latest Agenda and Presentations there.

Adjoining this the two concluding workshops were organised, the Concluding 2nd User Workshop of WP8 and then the Synthesis Evaluation Workshop of WP3 (30 November all day for the User WS and Friday morning 1/12. The Agendas are on the User and Evaluation Workshops page.

SMHI, Météo-France, Bonn University and the Met Office have run or are running their reanalyses in WP2 with the HARMONIE-ALADIN, ALADIN and MESCAN, COSMO and Unified Model systems. The years 1961-2015 exist from SMHI and can be retrieved via the ECMWF data portal. (Or directly from MARS if you have an ECMWF user account).

The Met Office Unified Model RRA, including an ensemble, is available for the periods 1979-1990 and 2000-2014 while the remaining 12 years are being produced during the remainder of 2017 and early 2018.and from 1979 and still being filled with data for the 1980s. The MESCAN surface 5 km reanalysis from Météo-France is available for 1981-2010 with the rest being produced and some rerun, all during the autumn of 2017.The 2005-2010 period has been produced at University of Bonn with the COSMO modelling system and also includes an ensemble.

Some problems have been discovered in the data or the availability which have been seen by new users of the data:

1. HARMONIE Relative humidity at pressure levels and 2m surface level: Humidities that originally were >100% have erroneously been set == 0. Ar least near the surface such 0 values can be assumed to be 100 or supersaturated.

2. HARMONIE sensible heat fluxes only exist for forecasts up to 6 hours and the values are missing over most of the land area.

3. HARMONIE maximum wind gusts since last postprocessing suffer from a significant spin down due to TKE at the start of the forecast so at least the 0-1 hour forecast range has a severe overestimation and should not be used.

4. Overestimation of precipitation can be seen in the HARMONIE evaluation (D 2.7 and D 3.6). Also the Met Office Ensemble has a severe overestimation during the first hours of the forecast range (D 2.14).


The schedule of production and archiving can be seen in the GANTT diagram which will be kept up to date.

The Data rescue activities have completed some 8.2 M data that include a lot of the sub-daily scale and almost all of them have undergone extensive quality controls and corrections.

A wide range of activities and results are shown in Newsletter No 3 downloadable under Publications.

On 28 -29 September 2016 a workshop was organized in which the FP7/H2020 Copernicus Climate Change projects shared their expertise and increased convergence on how to define, assess, and communicate uncertainties and data quality. The workshop was hosted by the European Commission in Brussels. See more and view the presentations on the Meeting Page.
