An IMPROVE monitoring site can have missing data for various reasons, e.g. a power outage at the monitoring site. In some instances, there is enough missing data that the monitoring site fails the completeness criteria to calculate a valid haze metric for the Regional Haze Rule (RHR) baseline period (2000-2004). The RHR guidance documents has procedures for filling in some missing values with “patched” data; however this criteria is strict and few values are actually filled in. A number of States have developed different procedures to fill in additional missing values and submitted these data to the VIEWS database. These data are referred to as “substituted” data to differentiate them from the RHR “patched” data. Currently substituted data are available from 19 monitoring sites. These sites were selected because they either did not have the required 3 years of valid data to calculate the RHR haze metrics for the baseline period or they did not have complete data for the year 2002. The Regional Planning Organizations modeled the year 2002 and monitoring data was needed to evaluate and use the modeling results.

IMPROVE Data Use: For journal publications, please inform Loretta Wilson (loretta.wilson@colostate.edu) of the planned publication. Drafts of publications will be reviewed upon request for issues that could affect the data interpretation. Preferred Reference: Please reference the Malm,et al. (1994) article below when using IMPROVE data. Malm, W. C., J. F. Sisler, D. Huffman, R. A. Eldred, and T. A. Cahill (1994), Spatial and seasonal trends in particle concentration and optical extinction in the United States, J. Geophys. Res., 99, 1347-1370. Preferred Acknowledgment: IMPROVE is a collaborative association of state, tribal, and federal agencies, and international partners. US Environmental Protection Agency is the primary funding source, with contracting and research support from the National Park Service. The Air Quality Group at the University of California, Davis is the central analytical laboratory, with ion analysis provided by Research Triangle Institute, and carbon analysis provided by Desert Research Institute.
