reference documentation of all the nodes available with their parameters


Please excuse my ignorance, Where can I find a documentation of the different processing nodes that are available with their parameters.
This would really help me creating a processing graph for some Sentinel3 data.
Is there such documentation available somewhere ?

Many thanks.

There is no document which describes all operators. But you can go to the command line and type gpt -h
This will give you a list of all available operators. And you can call
gpt OPERATOR_NAME -h which will give you a description of the parameters.
For general SNAP core operators, there are pages available in the SNAP Help.

For some operators there are special pages avaiable:
