1. Methods Results Conclusion Gathered and analyzed PM 2.5 and AOD data for 2 months (May-June 2011) Looked into patterns and consistency of data – for urban, suburban, and rural areas Differences among the geographical areas, and between PM 2.5 and AOD Comparison of Aerosol Optical Depth (AOD) and Surface Particulate Matter (PM 2.5 ) for New York State Arnold T. Arrozal, Olivia D. Reed, and Fred Moshary Department of Electrical Engineering, City College of New York, New York City Albany County Utica Newburgh White Plains CCNY Maspeth Six areas within the New York State were selected based on their geographical locations as urban (2 areas), suburban (2 areas) and rural (areas). These areas were selected to compare the aerosol optical depth (AOD) and surface particulate matter (PM 2.5 ). AOD was measured by Moderate Resolution Imaging Spectroradiometer (MODIS) and GOES (Geostationary Operational Environmental Satellite) Aerosol/Smoke Product (GASP) instruments while surface particulate matter (PM 2.5 ) was measured by Tapered Element Oscillating MicroBalance (TEOM). Overall, the results showed varying degrees of correlation. The R 2 of PM 2.5 between two areas ranged from a low 0.303 to a moderately strong 0.723. This result suggested that when the PM 2.5 between two areas is being compared, the R 2 becomes weaker as the distance between the areas increases. However, the R 2 of MODIS AOD between two areas ranged from a moderately strong 0.69 to a very strong 0.919. It was also found that the correlation (r) between PM 2.5 and MODIS AOD in each selected area was ranging from a moderately strong 0.64 to a very strong 0.93 with the exception of urban areas (City College of New York (CCNY) and Maspeth) where r was not available. However, the correlation (r) between PM 2.5 and GASP AOD in each selected area was ranging from a very weak -0.05 to a moderately weak 0.23. This results shows that MODIS AOD and GASP AOD were not consistent in measuring PM 2.5. It can be said that TEOM and MODIS AOD posted a moderately strong to a very strong correlation in measuring PM 2.5 while GASP AOD did not.
