ANNUAL TRENDS - AMBIENT MASS Annual Group 10, 50, 90 average concentrations of the total fine (PM2.5) and coarse (PM2.5-PM10) mass and major fine aerosol types. The fractional contribution of the aerosol types to the reconstructed fine aerosol mass is also provided. These data are for all IMPROVE sites with data from 1988 - 2001. These data were used to construct the long term trends aerosol trends. All calculations followed the procedures from the Draft Guidance for Tracking Progress Under the Regional Haze Rule (9/27/01). (see http://vista.cira.colostate.edu/improve/Publications/GuidanceDocs/guidancedocs.htm) A possible bias in the pre 6/1996 nitrate data and some of the eastern US particle sulfur data exists. For more information see http://vista.cira.colostate.edu/improve/Data/QA_QC/issues.htm. To minimize these biases SO4 ion data were used to replace all potentially biased sulfur data. A dataset with constant group 10, 50 and 90 ammonium nitrate values in all calculations is also available. Information about the IMPROVE monitoring sites can be obtained from: http://vista.cira.colostate.edu/improve/data/graphicViewer/metadata.asp VARIABLE DEFINITIONS AND UNITS: Group 10 = The average of the data between the 0th and 20th percentile Group 50 = The average of the data between the 40th and 60th percentile Group 90 = The average of the data between the 80th and 100th percentile TM = PM10 CM = COARSE MASS, THE DIFFERENCE OF PM10 AND PM2.5 -
