Meeting Notes:

(1) plans for the EVA Working Group over the next six months (10 minutes)
 
DataONE Post-Doc:  Aritra Dasgupta
Intern:  Jorge Poco
 
EVA 
1.     add functionality for model intercomparison

• based on data from the North American Carbon Program Regional Synthesis and MsMTIP
• look at interannual variability, spatial differences in carbon sources and sinks
• a priori clustering of models based on their structure – algorithms used to represent various ecosystem processes.  Do models that have similar structure behave similarly (and behave differently from those that have a different structure)?

2.     add benchmarking functionality to UV-CDAT

•  gridded observations – treat similar to model output
• use ILAMB and MsTMIP benchmarking algorithms and scoring embedded in UV-CDAT

 
 
Meetings / Telecons

• November 27 – this telecom 
• Early January teleconference – UV-CDAT and planning for the EVA Brooklyn meeting
• January 22-23, NYU-Poly, Brooklyn
  • Logistics:  Room block at the Brooklyn Marriott is being finalized
• February 7-8, MsTMIP workshop in Albuquerque
•  Monthly – bimonthly teleconferences
•  Perhaps a July 2013 Working Group Meeting

 
(2)  Short Presentation via WebEx:  Jorge Poco, NYU - Poly grad student "Analyzing / visualizing output from Terrestrial Biosphere Models using UV CDAT" (20 minutes)
 
code for UV-CDAT with some features added by Jorge will be available for download in about a month

(3) UV-CDAT discussion (10 minutes)
Usability

• UV-CDAT can access data from local desktop or from server (FTP/HTTP/OPeNDAP/DataONE)
• Claudio's group is working on parallelization of VisTrails workflow, which should speed up processing

 
additional analysis / visualization functionality for model output 
    

• K-means clustering -- can be added
  • part of a JAVA package that is integrated with VisTrails / UV-CDAT

 

• add basic analysis capabilities through VisTrails workflows
  • base level analysis modules within VisTrails:
    • common analysis capabilities like subsetting, regridding, units conversion, etc
    • Build modules to wrap UDUNITS functions (for units conversion)      
    • better handle CF-convention (preserve/propagte CF metadata through                      CDMS functions)
      
      
• Add benchmark analysis modules which can be readily used in VisTrails workflows to handle CF-compliant data files
  
  
• Model Structural Characteristics
  • easily toggle the inclusion or exclusion of model structure characteristics and how they influence the clustering of the outputs
  • turn on/off selected model characteristic components, changes shall be reflected in visualization interactively
  • may be useful to determine which model features / characteristics are critical 
•  

 
(4) plans to expand UV-CDAT functionality to include benchmarking (10 minutes)

Acton:  Cook to send out a poll for the next teleconference (early January)
