amonaroll Posted March 8, 2016 Report Share Posted March 8, 2016 I don't know if I'm looking in the wrong places but for some reason I cannot figure out how to do this problem: Given information characterizing the extinction coefficient of a layer of dust in the atmosphere and the observed reduction in outgoing radiation, calculate the thickness of the dust layer. I think it wants me to calculate Aerosol Optical Depth but I don't know how I would use an extinction coefficient and outgoing radiation. The competition in a couple days, if someone could explain it and perhaps provide an example that would be awesome!!! Quote Link to comment Share on other sites More sharing options...
Lurker Posted March 9, 2016 Report Share Posted March 9, 2016 Modis images has aerosol product http://lance-modis.eosdis.nasa.gov/ nice articles : http://www.cesbio.ups-tlse.fr/multitemp/?p=1710 Im not really familiar with aerosol research , sorry Quote Link to comment Share on other sites More sharing options...
pasfans01 Posted March 9, 2016 Report Share Posted March 9, 2016 in remote sensing, this is called visibility measurement and this is a part of Physical based Atmospheric Correction, Visibility ( in meteorological range/depth) could be measured using this equation V = 3.912 / B , where V = visibility (in kilometers) and B = visible Extinction coefficient, Just my 5 cent, 2 Quote Link to comment Share on other sites More sharing options...

But how is the reduced outgoing radiation used? Edited March 10, 2016 by amonaroll Quote Link to comment Share on other sites More sharing options...
pasfans01 Posted March 11, 2016 Report Share Posted March 11, 2016 hmm, forgot about that, found another way to measure visibility using bouguer-lambert law, looks at this doc https://www.google.co.id/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=0ahUKEwjniqqGtLfLAhXQwo4KHXLCAloQFggnMAE&url=https%3A%2F%2Fwww.wmo.int%2Fpages%2Fprog%2Fwww%2FIMOP%2Fpublications%2FCIMO-Guide%2FPrelim-2014Ed%2FPrelim2014Ed_P-I_Ch-9.pdf&usg=AFQjCNHWzIDYlSK1YlYK4NK4pHRPNTHs0g&sig2=AsEqY7o2WiyQRlGgiTPtBQ&bvm=bv.116573086,d.c2E Quote Link to comment Share on other sites More sharing options...
