“…The coastal plain areas are generally low and flat and the highlands, which represent the majority of the area, are generally heavily forested. (5) The San Joaquin Valley (SJV), CA, is an agricultural area characterized by poor air quality (Rosen et al, 2006;Sorek-Hamer et al, 2013), located southeast of San Francisco between the Coastal Mountain Range to the west and the Sierra Nevada Range to the east , and experiences a semi-Mediterranean climate.…”

The analysis results recommend incorporating the fine-mode AERONET AOD in MAIAC calibration. Specifically, they indicate the need to revisit MAIAC regional aerosol microphysical model assumptions used to generate look-up tables (LUTs) and conduct retrievals. Furthermore, relatively large variations in measured PM ratio shows that adding seasonality in aerosol microphysics used in LUTs, which is currently static, could also help improve accuracy of MAIAC retrievals. These results call for further scrutiny of satellite-borne AOD for better understanding of its limitations and relation to the vertical aerosol profile and particle size, shape, and composition.
