Can SeaDas l2gen output Rrs NIR band for Landsat 8?

by joeymcy » Sat Aug 07, 2021 5:20 am America/New_York

Hi, I am new to SeaDas and remote sensing. I am currently doing a project to predict chlorophyll a and suspended solid in Case 2 water in Hong Kong.

So I realized Near infrared red band is very important parameter in detecting chlorophyll. I ran the l2gen in default setting but I only got band 1-4 Rrs.

Is there any way i can get Rrs of Near infrared red band in l2gen ?

If not, is there any way i can do ocean color atmospheric correction to get visible band and Near infrared red band?

Thank you

In l2gen GUI, click the "products" tab. On the bottom, there is a "Selected Products" window, see if you are able to add Rrs_865 among other products. If Rrs_865 doesn't get erased after you click the Apply button, you can click the "main" tab and you should get the Rrs_865 band in your l2 products. Otherwise, I'll show you how to work around using command line.

Dear XuanYang,

Yes I found it. Just need to expands Rrs a bit.

I post a screencap here for future reference for other users.
