MERIS CoasColour Processors>CoastColour Atmosferic Correction?

Hello,
I have a tutorial wich they use of MERIS CoasColour Processors>CoastColour Atmosferic Correction.

But if look in SNAP i don’t see this button.
Is there an other option to do the same? or is there an easy way to make a chlorofyl picture?

thank you!!

This tutorial was written for BEAM. There these operators are available. But they have not been migrated to SNAP.
Also there exists the CoastColour on-demand processing.
You can apply for an account.

thank you marpet!

I downloaded BEAM 5.0 and used meris regional processor and it gives a better result.
I will try also the coast colour.
