(A) Chen et al., (2017)showed improvement in LAI retrieval when usingMAIAC surface reflectance as input; (B) Di et al.(2017) shows the risk of mortality curve as afunction of air quality at PM2.5 levels well below theNational Ambient Air Quality Standards (35µg/m3).National daily 1km PM2.5 for this study (2000-2012)was obtained using MAIAC AOD from MODIS.
