We have level 3 SMI data.
I need make the conversion from DN to aerosol optical thickness.
In HDF files, the slope for conversion equation is 0.002 but in SeaWiFS documentation is 0.005 .... which is the rigth value?
Thanks a lot
The meta-data is correct, the documentation is out-of-date.
Always trust the meta-data over the documentation, as parameters such as scale factors can be set dynamically, and the meta-data records what was actually applied. IMO, the actual value of these scale factors should not even be listed in the documentation.
