EUCOS objectives 2009-2011• OSE on EUCOS upper-air network redesign, to be conducted

during 2009 by ECMWF, OMSZ and HIRLAM Group;• Evaluation of the EURORISK PREVIEW Data Targeting System

Trial (2009/2010);• E-AMDAR humidity sensor trial and first phase of an operational

programme (2009/2010);• Develop specification for a new EUMETNET programme with a

centralised data hub and quality monitoring function (E-VCOMP);

• Second combined EUMETSAT/EUMETNET study to evaluate the impact of METOP on the ground based observing network;

• Collaboration with E-GVAP II on future integration into EUCOS;


Upper-air network redesign OSEScenario no 1: Baseline: All current satellite observations used in NWP (radiances, cloud-drift winds, scatt winds) + GUAN radiosonde network + GSN + hourly buoys (no ship data);Scenario no 2: Control run:All currently available data in the EUCOS area.Scenario no 3a: Experiment with horizontal spacing of 100 km for profiles.Baseline + terrestrial RaSo stations with 100 km horizontal spacing, thereby excluding RaSo stations if 3 hourly AMDAR measurements are available at those locations + AMDAR data, SHIP, BUOY, ASAP, WRWP, WP dataScenario no 3b:The same as for 3a but keeping 0 UTC radiosonde ascents at those sites which are excluded in scenario 3a because of the vicinity to an airportScenario no 4:Experiment with horizontal spacing of 250 km for profiles from radiosondes and aircraft.Scenario no 5:Experiment with horizontal spacing of 500 km for profiles from radiosondes and aircraft.


DTS – status December 2008• DTS-website can be found on ECMWF’s homepage:

www.ecmwf.int/research/EU_projects/PREVIEW/DTS/index.html

• During the 2008 trial phase 628 high impact cases were proposed and 548 accepted by the lead user;

• 21 countries participated by making extra observations;88% of requested radiosonde ascents from land stations had been deployed; 54% of requested ASAP soundings; in 181 cases E-AMDAR data were requested;

• The DTS is described in the latest issue of the “ECMWF newsletter”;

http://www.ecmwf.int/research/EU_projects/PREVIEW/DTS/index.html


DTS - outlook

• The trial period ended at 19 December 2008;

• EUCOS looks for: • a continuation of the DTS (just the technical part) during 2009

– a MoU has been negotiated with ECMWF;• A basic evaluation of the trial (e.g. cataloging of cases) – will

be done by UK Met Office (first quarter 2009);• A systematic evaluation of the impact of additional data on

NWP – preferably by data denial studies carried out by E-SAT members during 2009, results are expected for early 2010;


EUCOS interest in EG-CLIMET activities• Previous COST actions were taken over as EUMETNET programmes

(examples WINPROF, E-GVAP);• As a result of the current discussion on the EUMETNET strategy the

remit of EUCOS might be extended to local scale NWP and climate requirements;

• EUCOS is interested in the planned testbed observing system experiments and long term trials to judge cost efficiency of new observing systems;

• EUCOS could promote through its Science Advisory Team the close cooperation with NWP centres to make optimal use of observing data in assimilation techniques;

• EUCOS is interested in EG-CLIMET network design recommendations.


Thank you for your attention !


PREVIEW Data Targeting System (DTS)The aim of data targeting is to make additional observations when and where they will be most beneficial to subsequent forecasts. The locations, "sensitive areas", could vary from day to day and the supplementary observations will be most valuable if they help reduce uncertainty in cases of potential high-impact weather

A pre-operational Data Targeting System (DTS) has been developed to assess the feasibility of operational adaptive control of the observing system and as a facility to aid research projects using data targeting Met Office lead, partnering with ECMWF.

50% / 50% funding from EUCOS and EC under the framework of PREVIEW (www.preview-risk.com)

The DTS web tool has been developed at ECMWF and runs at ECMWF.

http://www.preview-risk.com/


Data Targeting – user needsBetter observational response ahead of potentially high-impact weather events

• System to better exploit existing observing systems – currently have rigid schedules

• Observational assets to be more adaptive in real time

Potentially improve forecast products • Reduce forecast uncertainties when ensemble products show differing

predictions• Aid accurate prediction of high impact weather events over Europe• Aid early warning - 24 to 72 hours forecasts• Aid crisis support within regions impacted by severe events


PREVIEW Data Targeting System (DTS)The DTS will provide an interactive web-based facility to request additional observations from the operational observing network.

Registered users of the DTS will be able to

• identify potential high-impact weather events, in particular cases with large uncertainty

• request sensitive area calculations for a given case: predictions of regions where additional observations are likely to have most impact in reducing the forecast uncertainty

• identify which additional observations to request

• issue requests for additional targeted observations
