You mean emissivity of that channel ?
Also, I have a question like if I want to convert TB to Bolometric temperature than how will I do that in RDR ? .
I am using ArcMap. How will I convert it to bolometric brightness temperature for channel 9 only . I have the formula but don't know how to implement ?
Another question about Zonal mean temperature ? It refers to zonal mean as if for certain range of lat , long ?
