UQ: Observations Workshop - January 17-19, 2012

Workshop Information

January 17, 2012 - 8:00am - January 19, 2012 - 12:00pm
Cooperative Institute for Climate and Satellites (CICS-NC)

LOCATION: Asheville, NC

The workshop was co-sponsored by the Cooperative Institute for Climate and Satellites (CICS-NC) and by SAMSI. It was organized in cooperation with the Program in Spatial Statistics and Environmental Statistics (SSES) at the Ohio State University. The event was hosted by CICS at its Asheville, NC, facilities.

Motivation and Goals

Observations are key to uncertainty quantification (UQ) in climate research because they provide a corroborating source of information about physical processes being modeled. However, observations have uncertainties and this poses a set of methodological and practical issues for comparing them to model simulations. The scientific themes of the workshop included:

  • Experimental design aspects of collecting ground-based and remotely-sensed observations;
  • Data fusion and homogenization: how to combine heterogeneous observational data sources to get a clearer picture of the true physical process;
  • Link to Uncertainty Quantification for projection of future climate based on past and present observations.


Participation was open for a limited number of external registrants. Speakers presented their views on the general issue of observations as it pertains to the quantification of uncertainty in various applications. Discussions were carried out throughout the workshop to encourage interaction and foster a deeper understanding of the research issues.
