1
The underpinning and crosscutting role and
responsibilities of the Instrument and Methods
of Observation Programme and CIMO in the
context of WIGOS
  • Dr. J. NashPresident of CIMO
  • TECO-2008, St Petersburg, 27-29 November

2
CIMO Mission
  • To promote and facilitate international
    standardisation and compatibility of
    meteorological observing systems used by Members
    within the WMO Global Observing System to improve
    quality of products and services of Members.

3
Aim of CIMO intercomparisons
  • To improve the quality and cost-effectiveness of
    surface based and upper air observing systems by
    exploiting existing national tests and performing
    global intercomparisons
  • To provide recommendations on system performance,
    improvements of instruments and methods of
    observation, suitable working references to WMO
    Members and instrument manufacturers.

4
CIMO Strategy
  • Support initiatives which by coordinating
    collective actions by Members with respect to
    observing systems produce results that exceed
    what each Member could produce unilaterally to
    meet their critical needs
  • Support capacity building in developing and least
    developed countries to close the gap between
    them and the developed countries
  • Support development of new observing equipment,
    critical to Members needs, collaborating with
    members of HMEI , the scientific community and
    other developers to facilitate a production of
    reliable instruments that are adequately tested
    before use.

Key Challenges
  • Improving sustainability of observing systems
  • Integrating remote sensing and in-situ observing
    systems
  • Monitoring in severe weather/climate conditions
  • Improving Weather radar calibration and
    evaluation of algorithms (QPF)
  • Development of technical expertise.

15
Expected Results, Key Performance Targets for
CIMO 1
  • Work of CIMO between 2007 and 2011 is expected to
    contribute to the WMO strategic expected result
    of -
  • The Integration of WMO Observing Systems
  • CIMO will still contribute to other strategic
    expected results, but will not receive direct
    funding for this.
  • Enhanced capabilities of NMHS in developing
    countries, particularly least developed countries
    , to fulfil their mandates
  • Enhanced capabilities of Members in multi-hazard
    early warning and disaster prevention and
    preparedness.

16
WMO Integrated Global Observing System Branch
includes Observing Systems Division, Space
Programme Office, GCOS Joint Planning Office,
WIGOS Planning Office
  • Observing systems Division OSD includes-
  • WWW Global Observing Systems Programme
  • Instruments and Methods of Observation Programme
  • Marine and Oceanographic observations, data
    management and information
  • Aeronautical observations

17
WIGOSa chance to work together to improve the
global observing systems so integration
activities should result in improved
partnerships, e.g. between research and
operations Needs to be a plan of actions or
mechanisms to ensure actions occur, more than
just excellent paperwork.
18
WIGOS
  • WIGOS will benefit society through enhanced
    availability and integration of global weather,
    climate and water observations contributed by
    constituent systems.

19
WIGOS
An observing system for atmospheric, oceanic and
terrestrial (including hydrological and
cryospheric) domains A system that improves WMO
observation management and management structures
and also encourages broadening of governance
frameworks (e.g. inter-agency co-sponsorship of
systems), with other scientific research or
environmental institutions. Increased
interoperability between the various systems with
particular attention given to complementarity
between the space-based and insitu components
To ensure that in broader governance
frameworks, WMO relationships with other
international entities are respected, sustained
and strengthened.
20
  • The benefits expected from WIGOS for the users of
    observations are-
  • Improved observation services
  • Increased quality and access to observations
  • More efficient use of resources in managing
    observing systems
  • Better preparedness to incorporate new observing
    systems and to interface with non-WMO systems.

21
WIGOS Integration Areas
  • Three key areas where standards will be applied-
  • Measurements and observations, must ensure
    component observing systems are functioning
    correctly and reporting observations in
    accordance with the known sampling and error
    characteristics for that type if system
  • Data exchange, discovery, access and retrieval
  • standards imposed by the use of WIS
  • End-product quality management, Quality
    monitoring needs to be associated with organised
    feedback to improve identified problems with
    observing systems

How to transform the concept into an action plan?
  • Different types of observing system require
    different approaches, e.g. satellites or ground
    based observing systems
  • CIMO activities fundamental to 1st and third
    areas and in contributing information to the
    Metadata for the second area
  • Documentation required so that users know how to
    link surface and space based observations to
    produce interoperable products for each
    meteorological variable.

24
Example of the upper wind network
  • Only functions well if a variety of systems are
    used together.
  • In these examples two insitu systems radiosondes
    and aircraft take snapshots over a specified path
    for a short time. The characteristic errors of
    these two types of measurements are different,
    although often of similar magnitude. The atypical
    errors that occasionally occur are quite
    different for the two systems.
  • Wind profiler winds are often integrated for 30
    minutes over a cross section of avout 1km at 2
    km,and 5 km at 10 km.
  • Weather radar winds are derived around a cone of
    wider crosssection, e.g. 7.5 km at 2 km and 5 km
    at 20 km, and will be usually sampled over a much
    shorter time period than the wind profiler winds.

Aircraft winds do not always Agree with
collocated aircraft winds, given real atmospheric
variability Weather radar winds only where it is
raining

Lower and middle troposphere. Satellite winds
from tracking cloud and water vapour structure.
Sampling is for much deeper layers than the
ground-based systems/aircraft. Comparison with
NWP fields is essential to eliminate false winds,
before values are reported

Upper troposphere. Satellite winds from tracking
cloud and water vapour structure. Sampling is
for much deeper layers thanThe ground-based
systems/aircraft. Comparison with NWP fields is
essential to eliminate false winds, before
values are reported

Looking in more details reveals some
suspiciousmeasurements that probably should have
been quality controlled
Poor weather radar winds
31
Time series of measurements also allows
identificationof atypical errors

32
Time series of measurements also allows
identificationof atypical errors
UK wind profiler for 6 September 2008
33
Is this wind profiler functioning correctly with
so many missing winds between 7 and 12 km?
34
This looks much better, but engineering tests
have Shown that the antenna needs renewal to
some extent.
Can the satellite winds resolve the strong wind
shear in the vertical seen here?
35
Errors estimated from the time series vary from
weekto week, see next slide as well
36
Errors estimated from the time series vary from
weekto week, so scattering conditions in the
atmosphere affectthe wind profiler performance.
Periods of poorer performance need to be flagged
to the users, but this does not happen now.
37
Some conclusions for upper winds integration
  • Uniformity of performance relies on-
  • Thorough testing of systems before large scale
    deployment
  • System maintenance regimes that maintain the
    performance of the system to the expected levels,
  • quality management that is effective and can
    detect anomalies and report them back to the
    system operators.
  • In some cases, monitoring will have to be
    performed on the internal functioning of the
    observing system as well as on the reported
    products.
  • Detailed evaluation of system performance from
    specialized tests and from the various monitoring
    methods

38
Underpin and crosscut in WIGOS?
  • Measurement standards and quality assurance and
    management are clearly areas where CIMO should
    aim to underpin the integration activities.
  • The crosscutting comes from the need to liaise
    with experts in other Technical Commissions to
    deal with a wider range of observing systems,
    than has currently been addressed in CIMO
    activities.

39
  • WIGOS has Pilot Projects to test improving
    coordination between a variety of Technical
    Commissions and also at least 6 national
    Demonstration Projects. The results will be used
    to establish whether a full scale implementation
    of WIGOS will justify the necessary investment.
  • CIMO needs to support all these Pilot Projects,
    and suitable national Demonstration Projects.
  • Integration of WWW/GOS and GAW into WIGOS
  • Integration of AMDAR into WIGOS
  • Elaborating the underpinning/crosscutting role
    and
  • responsibilities of the Instruments and
    Methods of Observation
  • Programme in the context of WIGOS.
  • Integration of marine meteorological and other
    appropriate
  • oceanic observations into WIGOS
  • Initiation of a Global Hydrological network in
    the context of
  • WIGOS

40
  • This means CIMO should start working now towards
  • For all elements of WIGOS respond to the
    requirements for standardized and compatible
    observations, including data content, quality and
    metadata. expansion of CIMO Guide?
  • Provide advice, studies and recommendations
    concerning effective and sustainable use of
    instruments and methods of observations,
    including quality management procedures such as
    methods of testing, calibration and quality
    assurance.
  • Conduct and /or coordinate global and regional
    field intercomparisons and performance testing of
    instruments and methods of observation.
  • Promote the development of measurement
    traceability to recognized international
    standards, including reference instruments and
    effective hierarchy of world, regional, national
    and lead centres for instrument calibration,
    development and testing.

41
This means CIMO should start working now towards
  • Encourage research and development of new
    approaches in the field of instruments and
    methods of observation of required variables.
    Improve liaison with the scientific research
    community and with HMEI
  • Promote the appropriate and economical production
    and use of instruments and methods of observation
    with particular attention to the needs of
    developing countries.
  • Promote , integration, inter-calibration,
    compatibility, and interoperability between space
    based and surface based (insitu and remote
    sensing) observations , including conducting
    test-bed observing experiments.
  • Support training and capacity building activities
    in the area of instruments and methods of
    observation.

42
Will the future see the death of WMO support to
conventional instrumentation or
improved Usefulness to all Members? This is our
responsibility

Questions answers
44
Instruments and Methods of Observation Programme
and CIMO
  • IMOP is to promote development , documentation,
    and the worldwide standardisation of
    meteorological and related geophysical and
    environmental instruments and instruments and
    methods of observation to meet agreed user needs
    for data
  • To ensure the the effective and economic use of
    instruments and methods of observation under
    varying working conditions and in differing
    technical infrastructures by providing technical
    standards, guidance material, performance
    specifications, technology transfer and training
    assistance.
  • and CIMO is responsible
  • For matters relating to international
    standardisation and compatibility of instruments
    and methods of observation and hence responsible
    for the IMOP Programme.

45
A new challengeExpected Results, Key Performance
Targets for CIMO 1
  • For activities to receive financial support in
    future,
  • WMO Members must see useful outputs from the
    activities of CIMO.
  • I would prefer that the usefulness of CIMO is
    measured in terms of outcomes achieved.
  • An expert team that does not function can no
    longer be tolerated.
  • Outputs must be more than useful discussions
    between experts, especially if these discussions
    do not represent any progress from the previous
    intersessional period.

46
