Motivations

• The spatial density of the SYNOP precipitations is absolutely inadequate for the validation and verification of the very high resolution models

• Creation of a “data hub for the precipitation observations” as already done by EUMETNET at the Met Office for the radar and wind-profiler data (“one stop chop” strategy)

• In the future - still a lot of development work to do – high resolution precipitation data will also be used in the data assimilation process

Situation today in Europe

Who is collecting today in Europe 24-hourly accumulated high-resolution precipitationobservations?

DWD (for Consortium COSMO)ECMWF (data from the Members)EU Project ENSEMBLESEUROGRID show-case (non yet accepted)

Report in the SRNWP web site.

Candidates

Two very good candidates:

= DWD- Does already this work but for COSMO

Members only

= ECMWF- Receives the data from all the Members and

associated Members and makes gridded analyses

Reason

• At least 3 times – in Council or ICWED Meetings – our Directors have expressed the wish of a model comparison over Europe.

• It has to be cheap. Thus only main models will be compared:

- LM (run by the DWD)- Aladin-France- HIRLAM (reference version at FMI)- UM (North-Atlantic / Europe version)

COSMO Annual Meeting 2005, 20-23 September 2005, Zurich (Switzerland) 14

Facts

• Already today the Met Office compares daily the precipitations of these 4 models over Great-Britain (24-hourly accumulated)

• The Met Office has been chosen for this comparison as the work will consist for him of an extension of an already existing task: several of its tools will be used directly

COSMO Annual Meeting 2005, 20-23 September 2005, Zurich (Switzerland) 15

Plan

• Verified will be from T+0 to T+48 at 6h intervals:- precipitations

- mean sea level pressure- 2m temperature- 10m wind

• Scores for precipitations:

- frequency bias

- equitable threat score

- log-odds ratio

- Hansen-Kuipers skill score

Results and Costs

• Results

Monthly mean statistics will be calculated and published on the Met Office external internet site under password protection

• Costs

The costs that will be submitted to the EUMETNET Council will amount to the salary of a scientist for 9 months per year
