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 All calculations followed the procedures from the Draft Guidance for Tracking Progress Under the Regional Haze Rule (9/27/01).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. Constant group 10, 50 and 90 ammonium nitrate value were used in all calculations, where the ammonium nitrate values were calculated from the 1997-99 data following the procedures from the Draft Guidance for Tracking Progress Under the Regional Haze Rule (9/27/01).
