Opening at 10am
The Acting President of CIMO, Dr Canterford welcomed attendees and noted the large number of participants at CIMO this year. Dr Canterford stated that CIMO was a strong Commission, with a strong outlook, as was indicated by the recognition of the work of CIMO at this year's WMO Executive Council. At which Council, CIMO had been acknowledged as the "cornerstone"  of WMO. The Acting President then introduced the Deputy Secretary General of WMO, Dr Hong Yan, to open the meeting.

Dr Hong Yan then opened the TECO. In his speech Dr Hong noted the work and cooperation between CIMO and HMEI and the useful participation, via HMEI, of manufacturers in the work of the Commission.

OPENING KEYNOTE
Innovations in observing systems and practices to meet the evolving needs of members 
by Dr Canterford
Key points for Dr Canterford, the Acting President of CIMO's presentation were:
§ Innovation
§ Collaboration, Integration and GEOS
§ Intercomparisons
§ Quality Management
§ Disaster Preparedness and Mitigation

The collaboration with Association of HMEI was particularly mentioned and Dr Canterford noted that CIMO was fortunate to have close cooperation with the Association. Standardisation and calibration of instruments was particularly mentioned as important issues that CIMO worked on. In talking about innovation in instrumentation Dr Canterford noted the importance of various issues including Interoperability. The work of Dr Nash and his co-authors for the paper recording the work done at Dar-es-Salam with an Interoperable Radiosonde System was noted and the authors of the paper were thanked for their work.

Collaboration between NMHSs, HMEI and manufacturers was seen as a benefit to all parties.

The fair and generous participation of manufacturers in Intercomparisons was noted.

Dr Canterford stressed that CIMO would cover the widest possible range of areas, beyond its traditional role in upper air and surface instrumentation, in order to provide technical experts and expertise to support WMO in achieving its goals.

In regard to Disaster Prevention and Mitigation, Dr Canterford noted that there have been innovations in the development of instruments for measurement of extreme conditions. For example:
§ anemometers and humidity probes
§ rainfall intensity instruments and pressure measurements for flood forecasting

Manufacturers were encouraged to develop more robust instruments with greater resilience to extreme weather.

SESSION 1 - NEW DEVELOPMENTS AND OPERATIONAL EXPERIENCE WITH SURFACE OBSERVATION TECHNOLOGY AND NATIONAL NETWORKS

Possibilities for expansion of surface weather observing systems in East Africa by D. Mburu - Doc 1(6)
The East African Meteorological has now split into three separate agencies, Uganda, Tanganyika and Kenya.
The tendency in East Africa is for automatic weather stations (AWS) to be installed. Despite the initial expense of AWS, the reduced need for maintenance appears to make them a more viable solution for the situation in East Africa.

Status, evaluation and new developments of the automated cloud observations in the Netherlands by W. Wauben et al. - Doc1(7)
Netherlands presented a report on their upgrading of 140 stations to fully automated stations. Some for synoptic, some for climatology and some for aeronautical. For cloud height they use ceilometers. The use of Nubiscope is being investigated for cloud heights.

SESSION 2 - NEW DEVELOPMENTS AND OPERATIONAL EXPERIENCE WITH UPPER-AIR OBSERVATION TECHNOLOGY

Keynote Presentation - New developments and operational experience with upper-air observation technology
by C. Gaffard
Please click here to see this document in pdf format
This presentation covered various improvements in Radiosonde technology, including the improvements that could be achieved by manufactures following problems identified at Intercomparisons they are involved with.

This UK Met office presentation showed the large improvements in measurement, processing and transmission while reducing the expenditure and running cost of ground based upper air network. The presentation noted that improvements in numerical weather and climate models need observations of atmospheric variables such as clouds, winds, temperature and humidity at increasingly high resolution in space and time.

New developments with upper-air sounding in China by F. Li - Doc 2(1)
The new Chinese Radiosonde system as presented has specifications that are fully CIMO compliant. The L-band Radiosonde is considered as similar quality to the RS-80 previously manufacturered by Vaisala, but of even better performance. 

The new GZZ GPS Radiosonde that China is now producing has superior quality to their L-band Radiosonde. China hopes to be able to participate, with the GPS Radiosonde, in the next WMO Intercomparison of High Quality Radiosondes.

China also advised that it is now upgrading its upper-air stations with 86 new radiosonde stations with L-band sondes in sparse data areas. The remaining 40 stations will be upgraded directly to GZZ GPS sondes during the next few years. They are also developing mobile systems for disaster situations.

Developments in Japan
The Upper-Air network of Japan was described. Japan has installed 31 wind profilers (Seawind/NOAA) operating at 1357 MHz. Twenty conventional radars will be converted to Doppler Radars so as to provide additional Doppler velocity data into the Numerical Weather Predication (NWP). Eighteen autosondes have been installed as part of the network. These are a mix of Vaisala and Meisei instruments. Japan is experimenting with ground-based microwave radiometers.

Developments in UK
The UK wind profiler network was described. The program consists of integration of radars, radiosondes profiler data and AMDAR data, to provide a complete coverage of upper-air data at all times

Developments in Germany
The German weather agency, DWD, talked about their experimenting with the Thies Laser Precipitation Monitor.

SESSION 3 - QUALITY MANAGEMENT, CALIBRATION, TESTING AND COMPARISON OF INSTRUMENTS AND OBSERVING SYSTEMS

Keynote Presentation - Quality management, calibration, testing and comparison of instruments and observing systems
by M. Leroy Chair CIMO ET SBII&CM
The need for good quality management across the whole range of meteorological instrumentation and systems, was strongly emphasised in this presentation.

Integrated quality management functions on AWS-level - GELOG SG station manager by G. Pevny (LOGOTRONIC)
Please click here to see this document in pdf format
This presentation first emphasised the need more detailed for quality guidelines in the CIMO guidelines. The presentation demonstrated the quality control built into the GELOG SG station manager. Logotronic believes this product to have the sort of quality control that would be an good basis for future standards of QC requirements.

SESSION 4 - TECHNOLOGY TRANSFER, CAPACITY BUILDING, TRAINING AND DEVELOPMENT OF THE REGIONAL INSTRUMENT CENTRES (RICs)

Keynote Presentation - Technology transfer, capacity building, training and development of RICs by J. Gorman
Please click here to see this document in pdf format

John Gorman from Australia made a very interesting presentation on calibration/tractability, points included:
- The identification of transfer standards
- Traceability is generally given too low a priority at most NMHSs
- The need to develop travelling standards
- In his presentation he suggested that Metrology be added as an application area to the HMEI Member Products Catalogue.

Training activities on meteorological instruments and observing systems in Turkey by E. Büyübas - Doc 4(5)
Turkey made a presentation on their recent training activities. They particularly invited weather radar manufacturers to make presentations of their systems in future Turkish training sessions, as they considered that important contributions had been made by the radar manufacturers' previous participation at these events.

RA III Radiosonde Training Workshop, Buenos Aires by J. Nash et al.- Doc 4(6)
John Nash made an informative presentation on the upper-air training recently conducted in Buenos Aires. Three HMEI members attended, InterMet, Modem and Vaisala, and contributed valuable information at their training sessions. In particular the trainees were able to see different sonde systems from the different manufacturers and this was noted as being extremely important. Dr Nash mentioned that this was the best training session he had been involved with and that the involvement of the manufacturers was part of the reason for this success.

SESSION 5 - TRENDS AND CHALLENGES: NATIONAL TO INTERNATIONAL NETWORKS - GLOBAL EARTH OBSERVING SYSTEMS (GEOSS), DISASTER PREVENTION AND MITIGATION (BPM), WMO QUALITY MANAGEMENT FRAMEWORK (QMF), WMO INFORMATION SYSTEM (WIS)

Keynote Presentation - Tends and challenges: national to international networks by J. Nash (CIMO Vice- President)
Click here to see this document in pdf format
Dr Nash made a number of key points and asked key questions in his presentation. In particular he asked the audience to consider the following points:
§ Quality Management; it needs to be ensured that QM is not just the appearance of following the QM procedures, they need to actually work and be effective.
§ Volunteerism, laudable as it may seem in principle, cannot guarantee the responsibility being taken for the end product in the way paying for a service does. It is not satisfactory, because there is no comeback where there is no payment involved. More money needs to be invested to ensure quality rather than depending on volunteers.
§ There is problem of CIMO creditability of (as is at times the case) measurements and data are still not of adequate standard, i.e. as specified by CIMO.
§ CIMO data and information must be well dissemination to the wider community, including manufacturers, in order that the usefulness of CIMO's data and information is maximised.

Australia's composite observing system: identifying future directions by R. Atkinson, et al. - Doc 5(1)
Australia is looking to the future and boosting investment in new and improved technologies.
The points that came out of this presentation are as follows:
§ Increase needed of network coverage, particularly in the surface observations and radar
§ AMDAR observations continue to be essential in Australia for good coverage
§ Wind Profilers need further evaluation as potential replacement for Radar Windfinding
§ Automation is good, but there is nevertheless a critical need for recruitment and training of observers
§ Radiosondes may be expensive to buy and maintain but are very much still necessary
§ Quality Management needs to be introduced; Quality Assurance not just Quality Control
§ Improved network design is needed
§ They are looking to ensure adherence to climate monitoring principles.
§ Data archiving and retrieval to be strengthened
§ Australia will be looking to CIMO to provide the guidance in many of these matters

Integrated national in-situ observing network by I. Zahumensky - Doc 5(3)
This presentation defined what an integrated network should be and emphasised the potential importance and benefits of integrated systems and networks.
The main components of integration involve the following steps:
§ User needs and and requirements
§ Knowledge of current national observing network
§ Required changes
§ Priorities
§ Integration design
§ Planning and strategy
§ Implementation

Challenges posed by the WMO Integrated Observing System (IOS) by Dr J. Nash - Doc 5(5)
Some proposed points for the achievement of IOS, noted in the presentation, were:
§ CIMO needs to become more involved in research and development area
§ Substandard data needs to be addressed and rectified
§ Expertise needs to be made available for extensive needed training
§ There needs to be investment in the development of instruments and the science behind this
§ Via COST coordination of activities for integration across Europe
§ More Testbed projects to be set up
In summing up the presentation noted that having collaborative projects with CIMO, the scientific community and manufacturers, were essential for the work for an Integrated Observing System.

Global Climate Observing System (GCOS) - Requirements and realities of providing overlapping Radiosonde flight series data for long-term climate continuity by C. Bower - Doc 5(6)
There are 6 Radiosonde manufacturers/providers used in GUAN.
Because of:
§ Radiosonde changes
§ Algorithm changes
§ Provider changes
It has been recommended that there be a one year overlapping study of old versus new equipment.

However the feasibility of this recommendation is not good considering:
§ Difficulties due to changes in technology
§ For many countries/regions it is not affordable
§ No flight series have yet been performed

ROUND TABLE DISCUSSIONS
During the Round Table Discussions, the point was raised that CIMO would like HMEI to promote the CIMO Guide to HMEI members, in order that CIMO guidelines would be implemented throughout the designing of instruments and systems.
HMEI Note:
The CIMO Guide has previously only been available by purchase from WMO. However it is now going to be supplied free, from the CIMO website. There has been a link from the HMEI website to the link for the CIMO Guide for some time, under Technical Information. However it is worth HMEI Members noting that the updated CIMO Guide, in draft format, is currently available at this CIMO page link www.wmo.int/web/www/IMOP/publications/WMO-8-Guide-contents.html  

1st Professor Dr Vilho Väisälä Award for the Development and Implementation of the Instruments and Methods of Observation
This was awarded by the Secretary General of WMO, Michel Jarraud, and the CEO of Vaisala, Kjell Forsén, to Messrs J. Nash, R. Smout, M. Smees (all from the United Kingdom) and C. Bower (USA) for the paper entitled “Dar-es-Salaam demonstration test of IMS 1600 Integrated Upper Air System, Dar-es-Salaam, 18-30 October 2004published in IOM Report No .82, TD-1265,  May 2005. This paper reported on the interoperable system from InterMet demonstrated in Dar-es-Salaam.

Dr. Gill Ryall from the United Kingdom noted the importance of this paper, considering the potential benefits of interoperable systems for the least developed countries.

On accepting the award on behalf of the four authors, Dr John Nash expressed his thanks to his colleagues and to Vaisala. He also thanked those in Dar-es-Salaam who had helped with the demonstration. Dr Nash went on to thank International Met Systems (InterMet) and Mr. Clowney from that company. He said that there had been many discussions with Mr. Clowney and that there was a good relationship with InterMet as the producer of this system.

Closing of the conference
The conference was closed at 5.40pm, Wednesday 6th December, 2006.
