I manage a group that performs the particulate matter (PM) monitoring for the Interagency Monitoring for PROtected Visual Environments (IMPROVE) program.  We are responsible for maintaining the samplers, supporting the local operators, sending sampling supplies to the sites, and analyzing collected samples at approximately 170 sites.  We collect and analyze almost 80,000 samples per year.


Characterizing data quality to gain a better understanding of the sources of error in the measurements and the suitability of data for particular investigations, such as source apportionment or temporal trends analyses.  

Improving quality assurance protocols to identify and reduce errors in both field sample collection and laboratory analyses, including developing new reference materials to evaluate XRF measurements.
