I have AEORNET AOD range (lets say) from 0.1 to 1.0 and I want to divide it into three different ranges: low, medium and high AOD values. Is there any automatic method to select these ranges?
If you look under the Special Data Requests section of the enclosed NASA AERONET webpage, there are two names (with e-mail links for each) that you could contact to find out how to subdivide your AOD measurements.
