In WP1 over 5.3 million data have now been digitized. This is way above the target promised for UERRA (3.5 million) so the digitizing has gone better than expected. They are from a small number of countries due to the availability of original data or scanned images. They are from Slovenia, Germany, .... and more from Germany, France and Spain will be forthcoming.

In UERRA the emphasis is on sub-daily data (as opposed to daily or monthly means. This is so that the Numerical Weather Prediction (NWP) model based reanalyses can use hourly or six-hourly data in their assimilation time windows.

Moreover, the period after 1960 is the priority for UERRA since the Regional reanalyses start from 1961 (SMHI and Météo-France) or 1978 in case of the Met Office.

The figure shows the distribution of the rescues and processed (quality controlled and corrected) data. (Please click on the Figure to see the full extent).


It is important to check for gross errors and supervise the digitization.

The coverage over time in European regions is shown below. While there are already quite a lot of observations available in southern Europe, there is quite a lot of data missing in northern Europe (e.g. Sweden and Norway) see below. Data is being or has been digitized nationally and the original data (on paper Journals) are not readily passed aroung from the national Meteorological Services (NMSs). It remains for those services to submit their data to the international data bases (like ISPD and ISD within NOAA)

The Climatic Research Unit of University of East Anglia has gone through an exercise to identify which data already exist in the ECMWF Mars archives and compared with the rescued data. There are e.g. difficulties identifying stations at the same (almost) location when AWS replaced manual ones. A data set from EURO4M has been encoded to ODB format but there are still some issues before it can go into ECMWF archives (sse later discussions).
