According to my knowledge of remote sensing the lidar requires insitu measurements and can be interfered with and biased by the climatic conditions of the study area, are there any alternatives to this methodology for the quantification of PM 2.5 and PM 10 and what is the best type of image to quantify these aerosols?
Dear Mounsif,
Remote sensing has been widely used for environmental application such as for air quality and water quality studies. But the atmosphere affects satellite images of the Earth's surface in the solar spectrum. So, the signal observe by the satellite sensor was the sum of the effects from the ground and atmosphere.
As far as your question is concerned, of course we can monitor air quality by remote sensing satellite imagery. You would know of Aerosols monitoring with the MODIS, MISR, OMI, and VIIRS satellite instruments and various other Application of Satellite Data to Particulate, Smoke and Dust -Monitoring Satellite derived aerosol optical depth-PM 2.5 relationships. However, we have to acknowledge that there is certain uncertainty during the retrieval.
A large number of publications are available on this topic, especially to improve the correlation between satellite data (e.g. AOD) and ground-monitored levels (e.g. PM). They can be easily found online.

You can take good ideas and informations about that in this paper:

Thank you for this article it has been a great help to me
