BACKGROUND AND SCOPE:
The 2009 Chemistry-Climate Modeling Validation (CCMVal) Workshop will focus on
process-oriented validation and comparison of coupled chemistry-climate models
(CCMs). It will include discussion of advances in Chemistry-Climate
Modeling of the stratospheric ozone layer, stratospheric climate and climate
variability, and the coupled ozone-climate response to natural and
anthropogenic forcings. This workshop is part of the SPARC CCMVal activity
which aims to bring the expertise obtained from interpreting measurements and
process-based modeling into global models, thus improving our confidence in
future projections from CCMs.
The main theme of the workshop will be on
progress with the SPARC CCMVal report. It will include updates by the lead
authors of the chapters, presentation of other related advances made by the
various modeling groups, and discussion of the results presented in the
first-order draft of the report. Opportunities will exist for discussion
of new observations and process-model studies that lead to new methods that
can be used for CCM evaluation.
The main meeting (1-3 June 2009) will be centered on the CCMVal Report chapters. It will include a limited number of oral presentations and will
emphasize discussion about progress with the CCMVal Report. Poster
sessions will provide opportunities for a large number of related
results to be presented.
Individual SPARC CCMVal Report chapter meetings (4 June 2009). Chapter
lead authors will provide information to their co-authors about the timing,
location and scope of these meetings.
One Day CCMVal Diagnostic Tool & NCL Tutorial (5 June 2009). This one day tutorial will describe the new CCMVal diagnostic package for analyzing
model output, and provide an introduction to the NCAR Command Language (NCL)
graphics package used within the diagnostics. Topics will include:
- Introduction to the diagnostic package (how to run it)
- Description of how to use the tool for analysis using NCL
- Introduction to NCL: File I/O, data analysis, basic graphics commands,
- Tour of NCL resources (Web site, tutorials)
- Examples of using NCL to process CCMVal output
