ANNOUNCEMENT OF
the Joint SPARC DATA ASSIMILATION and SPARC-IPY Workshop

September 4-7, 2007 to be held at the Fields Institute
TORONTO, Canada

 

 

Dear colleagues,
It is our pleasure to invite you to participate in the Fifth Stratospheric Processes And their Role in Climate (SPARC) Data Assimilation (SPARC-DA5) workshop, in Toronto, the Canada during Sept. 4-7, 2007. This workshop will held jointly with the SPARC International Polar Year workshop. Data assimilation will be the focus of the first three days (4-6 Sept.), while IPY will be the focus during 6-7 Sept. One day (Sept. 6) will be in common to both. For descriptions of our last two SPARC-DA workshops, please check our meeting reports in SPARC Newsletters No. 26 and 28. http://www.atmosp.physics.utoronto.ca/SPARC/Newsletters.html

The goal of the SPARC-DA5 workshop is to motivate and better understand data assimilation through the science of the middle atmosphere. Data assimilation requires a knowledge of measurement and model errors which, in turn, require knowledge of the true underlying system- the middle atmosphere. Therefore, advancement of assimilation techniques requires interaction of assimilators with dynamicists, chemists and users of assimilation products. Thus, this workshop aims to bring these various groups together. While contributions from all aspects of middle atmosphere (chemical and dynamical) data assimilation are sought, a few key areas will be highlighted. The following experts were invited to broaden our understanding of the true atmospheric system, highlight issues with assimilated products and help focus discussions in these areas:

• International Polar Year (IPY): Gloria Manney
• Stratosphere-Troposphere coupling: Mark Baldwin, Adam Scaife
• the Mesosphere: Charles McLandress

The SPARC-IPY workshop will bring together the participants and collaborators in the SPARC-IPY activity, to assess plans and capabilities and to discuss synergies and science outcomes. The theme of SPARC-IPY is vertical coupling from troposphere to mesosphere in the polar vortices (in both hemispheres), in terms of both dynamics and chemistry. As a major component of SPARC-IPY concerns the production and analysis of data assimilation products under the auspices of the SPARC DAWG, it makes sense to hold the two workshops together. The common day will focus on the use of the DA products, while the fourth day will focus on the measurement activities.


The web-site for the SPARC-DA5 and SPARC-IPY workshops is:
http://www.fields.utoronto.ca/programs/scientific/07-08/data_assim/
The workshops will be held at the Fields Institute in the University of Toronto downtown campus. A block of rooms at the Holiday Inn Toronto Midtown hotel has been reserved for participants. The deadline for reserving a room is 30 April 2007. Registration will be through the website above. Depending on funding, a small meeting fee (up to $50 Cdn) may be charged. The deadline for abstract submission is June 1, 2007. Please mark these dates in your calendars.

Please forward this invitation to anyone who may be interested.
If you DO NOT wish to receive further information about this workshop, please email sparc@atmosp.physics.utoronto.ca and request to be removed from this mail list.


Best wishes,
Saroja Polavarapu and Ted Shepherd, organizers
