Difference between MAR or PS OLCI L1 products?

Hi,

Are the MAR and PS products the same at Level 1?
And are all coastal scenes processed by both MAR and PS?
I can’t find the corresponding MAR Level-1 product for this Level-2 product:
S3A_OL_2_WFR____20220522T095902_20220522T100202_20220523T234751_0179_085_293_1980_MAR_O_NT_003.SEN3
So I’m wondering if I can just use the PS product instead.

Cheers + thanks for any help in advance!

Yes, you can use it. MAR and PS specify only the processing centre where the data has been processed. How the data is processed is independent from the location.
