Atmospheric correction L2A parameters


#1

Hello,

i want to automate a working chain. For that i want to check at first if the input product is L1C or L2A. If the product is L1C i want to perform an atmospheric correction with Sen2Cor.
What are the parameters for a L2A product downloaded from the open hub or from the product library in SNAP? Is there a list or documentation for that? Or are that just the default settings from Sen2Cor?

All the best

Hello,

look into the L2A-DQR for configuration differences between L2A-products which you download from scihub and processing yourself.
