I want to analyze the amount of SO2 emitted from volcanic activity. I will use ASTER TIR because they provide multispectral TIR data.i saw some people talking about streaching. But, I don't know how to do it.
Hello,
You could look into the volcanic SO2 retrieval correction algorithms proposed by Corradini and Campion.
I am attaching some of the literatures that may be useful for you to analyze the concentration. The authors have also used other sensors like MODIS , SERVI dataset etc.
Several techniques including band ratios have become popular in retrieving volcanic SO2, which not only depend on atmospheric humidity, sulfate aerosols, surface altitude and emissivity but also on the raw radiance values. You can look into the paper of Campion.
I am also attaching one of the presentation by Simon Carn. This presents the basic idea of extracting SO2 from the remotely sensed images.
Happy learning.
