Questions and Notes[edit | edit source]
use ~~~ to sign comments/questions.
- Promised land is using AOD observations in place of surface-based monitors. Need system approach of observations and models Erinmr
- Follow-up with NARSTO Ref #4 for satellite applications of pollution. Confusion about relevance of satellite observations for space/time
- Need to ID limitations of space-based measurements identified in Hoff paper.
- AOD -> PM needs physical models that account for particle characteristics, surface reflectivity without model PM and AOD are not equivalent
- Temporal resolution is off - surface monitors are 24hr average and these can't be compared with the daily snapshot
- need to better understand the Fresno/Satellite comparison - but I think the bottom line is that according to satellites winter would be low PM2.5 concentrations, however b/c of surface data we know that it is actually high surface concentrations. differences could arise from shallow mixing layer
- Data access issues to get MODIS AOD, Aeronet and supersite data from Fresno
