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.
