|Description=The paper is a discussion on the [[Hoff: Remote Sensing of Particulate Pollution from Space| Critical Review paper by Hoff and Christopher]]. The discussion comments on the satellite history, strengths/weaknesses of satellite observations for AQ management and concludes with summary of remote sensing applications to aq.

* Promised land is using AOD observations in place of surface-based monitors. Need system approach of observations and models [[User:Erinmr|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
