actually, I downloaded images L1A -> L1B-> L2gen in this state I do processing options-> aer_opt-> I chose the athmospheric correction then I do the validation of my data in situ my question: are these corrections reliable?
Well, it depends. If you use the default (aer_opt=-2: Multi-scattering with 2-band, RH-based model selection and iterative NIR correction) then yes. As reliable as we can validate (which we've done, and made those results available). Other options are are not as well validated, and may or may not be appropriate for use in your region of interest. The various atmospheric correction options we've made available in the l2gen program are there for users to try as they may provide a better solution. Nothing is guaranteed.
