Sentinel 2 - Band 1 missing ?

[Tristan PETIT]

Dear all,

I am new to arcsi and I am first trying it with Sentinel 2 images. Arcsi seems to produce nice quality reflectance spectra over water in coastal areas.

However, the produced L2 images do not contain the first spectral band (centered at 443nm).

I took a look at the source code and indeed, this seems not implemented (eg. in the "Calc6SCoefficients" function of the "arcsisensorsentinel2.py" script, there is no reference to band 1).

Could anybody confirm this? If it is the case, I wanted to know what is the reason for this?

If it is the case, would it be easy or not to add this spectral band to arcsi? If yes, I would be happy to contribute to the code!

Thanks,

Ttristan
