2. HAQAST Hi-Res Tiger Team: PM2.5 health impacts
Resolving PM2.5 variation within cities can influence estimated health impacts
Objective: PM2.5 health impacts at neighborhood scale
Boston, Los Angeles, New York City, and Washington DC
Existing satellite-derived PM2.5 concentrations at 0.01°x0.01° from van Donkelaar et al. (2016) for all cities (MODIS, MISR, SeaWIFS, CALIOP, GEOS-Chem, AERONET, ground measurements)
New MAIAC-derived PM2.5 concentrations at 100m for NYC, scaled up to 250m
Census-tract level baseline disease rates from CDC
Block level population allocated to census tracts using PopGrid software
Health impact functions in BenMAP-CE software
Kheirbek et al., Env. Health, 2016
1km data from combining CMAQ with monitor values

3. Disease rates vary within cities: Asthma prevalence (2014) at census tract level
Boston
n=437 DC
n=179
Similar data/maps available for other diseases LA
n=3494
NYC
n=2167

Census-tract level health impacts attributable to PM2.5 (cases per 100,000)
