What is EUMETNET?
EUMETNET is a network grouping of 21 National Met
Services in Europe that provides a framework to
organise operational and developmental co-operative
programmes between Services.
It provides a framework to organise funded co-operative
programmes between the Members in areas such as:
 Observing
 Data processing
 Basic forecasting products
 Research and development
 Training packages

What is EUCOS

EUCOS is the EUMETNET Composite Observing System. A
programme to deliver terrestrially based operational observations
for the efficient improvement of NWP in Europe.
 The EUCOS Programme consists of fully cost compensated
activities, such as E-AMDAR, significantly cost compensated
activities such as E-ASAP and E-SURFMAR and co-ordination of
voluntary contributions such as radiosonde and surface networks.
 In addition studies to determine future requirements and quality
monitoring and support activities for the operational programme is
also provided by the programme.
 EUCOS success relies heavily on the continued support of the
Members – it only works because the Members want it to work.

The Challenge & Strategy for EUCOS
 To improve the quality and make more cost effective
observations for the enhancement of regional NWP
performance in the 1 to 3 day forecast period in the
European area of interest.
 Achieved through resource transfer from the relatively
well observed territorial areas to the poorly observed
territorial and predominantly maritime areas.
 Achieved by EUMETNET Members committing
themselves to co-funding the programme through a fair
(GNI) cost sharing system.

Operational Programme Development
1) Start up phase – technology demonstration*, negotiation with
Members and Suppliers, agreeing common operating practices,
reviewing requirements and proposing a way forward.
2) Initial Operational Phase – implement recommendations from ‘1’,
set simple performance targets, evaluate impact on performances
and value for money from programme.
3) Mature Operational Phase – review programme following
experiences gained from ‘2’. Targets now more specific,
geographical rather than just quantities.

Operational Programme Areas

E-AMDAR – tasked with delivering the European wide AMDAR
data requirement, approx 12M observations pa. Budget 1.4M€ pa
 E-ASAP – tasked with delivering the oceanic radiosonde
programme, approx 5000 profiles pa from 16 ASAP units. Budget
1.9M€
 E-SURFMAR – tasked with delivering improved surface pressure
measurement coverage in Oceanic region. Budget 0.9M€
 Territorial Radiosonde – targets established for a subset of
Members radiosonde stations in terms of data volumes, quality,
height of ascent and timeliness. Budget 0.2M€
 Surface Networks – targets focussed on basic met parameters –
those that can be assimilated by NWP systems. No Budget!

Network Quality Monitoring

If we are investing significant amounts of money making
observations we should also invest in ensuring the observations
meet the requirements and poor quality data is identified and,
where possible, corrective action is undertaken.
 EUCOS quality monitoring is reliant on using NWP background
fields for assessing the quality of the observations.
 Upper Air parameters monitored included:





Timeliness, both threshold and breakthrough levels
Availability of data, compared with assumed operational programme
100hPa Height, Temperature and U & V wind vectors
Burst height for radiosonde network

E-ASAP Programme Challenges

Operating an ASAP system is not straightforward. Managing an
ASAP network is a challenge. Multiple ships, multiple systems,
multiple ‘home’ ports, launching problems and just when the
crews are fully trained they change.
 Senior Management have little understanding of the operation of
ASAP – some even assume ASAPs are fully automatic! Therefore
they cannot understand the cost of the programme.
 Modern NWP assimilation systems have difficulties dealing with
isolated radiosonde profiles. More so in critical conditions.
Fortunately this had been recognised (finally) and now forms one
of the activities within the European THORPEX science plan
 In the future the ASAP programme will become more adaptive,
responding to targeting instructions from NWP sensitivity
calculations.

EUCOS – Studies Programme
 The EUCOS Studies Programme is designed to enable
objective decisions to be made about the evolution of
the operational observing networks to support regional
NWP
 Are the correct parameters being observed?
 Is the current network configuration optimised?
 Where should future investments be made?
 What weaknesses exist and how should they be tackled?
 Current Studies Programme activities include
 Targeted observing development
 Space – Terrestrial Observing System Experiments
 Revised Network Design Evaluation
 Technology Demonstrations

Space - Terrestrial Study Programme
• A 2-year EUMETNET / EUMETSAT study to quantify the relative
impacts on NWP of the components of the space and terrestrial
observing sub-systems.
 EUCOS will deliver the evaluation of the terrestrial components in
conjunction with DMI, ECMWF, Met.No, UK Met Office and OMSZ
 In addition to the impacts of radiosonde, AMDAR and Wind Profilers
the study will also seek to identify the specific impact of the E-ASAP
and E-AMDAR data on the quality of European regional scale NWP
products.
 Results are out and a report will be published in early 2007.
