Dear colleagues,

We are very pleased that you will be able to attend the IPCC WGI/WGII
joint Expert Meeting on Detection and Attribution in Geneva on 14-16
September 2009. Earlier in the week the WGI TSU sent all participants the
final draft programme for the EM D&A that has been put together based on
input from the Scientific Steering Committee and the WG TSUs and Co-Chairs
as well as discussions at and since the AR5 Scoping Meeting in Venice
(attached again for your convenience).

As you will see, there will be four Break Out Group sessions for
discussion and a final session on the last morning that concentrates on
drafting bullets with key conclusions and an outline for the Good Practice
Guidelines for approval in the final plenary session. Having considered
various suggestions and options for the organization and structure of the
BOGs, it has been decided to adopt a matrix structure with two distinct
blocks. In Part A the BOGs will be organised by the kinds of detection and
attribution issues addressed (extremes, global, regional) looking at the
themes that need consideration for the Guidelines (methods and
definitions, data and other requirements, forcing factors, etc.). In Part
B the BOGs will be refocused and regrouped so that the discussions can
home in on these themes.

The agenda allows a fair amount of time for report-back and discussion
during which the participants would hopefully reach consensus on the key
points for inclusion in the guidance document. Each chair/rapporteur team
will be asked to write a very brief summary of the discussions,
highlighting key conclusions. These summaries can also be included as
supporting material in the final meeting report. We would like to leave
the meeting with the participants having agreed on the key conclusions in
the final session.

Thus we are proposing two sets of BOG Chairs and rapporteurs, based on
suggestions from the SSC and from both WGs, and we would like to secure
your agreement to act as BOG Chair or rapporteur as indicated below:

Part A
BOG1 Extreme Events: chair Neville Smith, rapporteur Sari Kovats
BOG2 Global Scale: chair Nirivololona Raholijao, rapporteur Camille Parmesan
BOG3 Regional Scale: chair Serge Planton, rapporteur Gino Cassassa

Part B
BOG1 Methods and Definitions: chair Francis Zwiers, rapporteur Daithi Stone
BOG2 Data and other Requirements: chair Matilde Rusticucci, rapporteur Guy
Midgley
BOG3 Forcing Factors and Confounding Influences: chair Linda Mearns,
rapporteur Phil Jones

The BOGs are fundamental to the purpose of the Expert Meeting and will be
a deciding factor in its success so we would very much appreciate it if
you would agree to take on this role.

I look forward to hearing from you soon, hopefully with a positive
response. If you have any questions, please do not hesitate to get in
touch with me

Best regards,

Pauline & Kris
on behalf of WG1 & WG2
