Re: OCSSW installation

Hello Xuanyang, Thank you very much for your help. Before I saw your message, I installed OCSSW successfully by a different method which was to install it from seadas software. So I did not try your update code. Hopefully, it will work. It seems that somewhere in the code is wrong. In addition, I ca...

Re: OCSSW installation

Hello Xuanyang,

Thank you very much for your reply. When I tried your first code, I got the same error as before. So I think I may need to download this file: OCSSW_bash.env.v7.5.3 and put it into /tmp. Do you know where to download this file?

Yes, I could run your second code.

Kind regards,
Sunny.

Re: OCSSW configuration

Thank you for your reply! Indeed, I made a mistake of my [SeaDAS_install_dir] which should be '/home/mmy/seadas-7.5.3/'.

Good to know the udpate of seadas. I will try it later.

Thank you,
Mengmeng.

Re: How to convert airborne radiance to reflectance?

Hello,

I found one method to convert the airborne at-sensor radiance to at-sensor reflectance (Hanuš et al., 2016). In this method, the at-sensor reflectance (also called apparent reflectance) was calculated by dividing the at-sensor radiance by the downwelling irradiance.

Kind regards,
Mengmeng.
