Research Title: Diurnal Assessment of Aerosol Optical Depth Products from GOES_ABI with AERONET for PM25

Research Project Synopsis: Surface fine particulate matter (PM2.5) is a significant health concern. Unfortunately, conventional monitoring of PM25 is hampered by cost which limits spatial coverage but satellites can potentially fill this spatial gap. With the recent launch of GOES16 Advanced Baseline Imager (ABI), we can extract AODs at 5 minute resolution allowing better temporal coverage over the day but questions about relating AOD to PM25 at different times of the day are critical and the main purpose of our research is to compare the diurnal error budgets of the AOD product with the error budgets we observe in comparison to the diurnal variability in PM25 estimators based on AOD retrievals.
