P013: Receptor Modeling Study to Determine the Sources of Observed Ambient Particulate Matter in the Lake Tahoe Basin

Lake Tahoe Source Attribution Study (LTSAS) to determine the sources of observed PM in the Lake Tahoe Basin; including analyze the Lake Tahoe Atmospheric Deposition Study (LTADS) and Desert Research Institute (DRI) data to distinguish sub-sets of site and seasonal data to assess seasonal trends, use multivariate statistical procedures to identify factors and groups of chemical species of relevance within the measured data set, compile a set of chemical source profiles applicable to the receptor modeling of the LTADS ambient results and apply the CMB receptor model to the LTADS data to determine the sources of the observed PM.
