IMPROVE Carbon Issues and Trends, Workshop
October 20, 2010, Skamania Lodge, Stevenson, WA

The day before the 2010 IMPROVE steering committee meeting, a workshop was held to explore the fine particulate carbon concentrations measured in the IMPROVE and CSN monitoring networks. The workshop was focused on the spatial and long-term patterns in the organic, elemental and total carbon measurements as well as potential carbon measurement issues and their effects on the carbon concentration patterns.

Meeting agenda and participants.  Each agenda item is linked to the meeting presentation.
