Dear agrosu1978,
I think that the doToa = True is mandatory in your case, as it is the step necessary to convert digital counts to Top Of Atmosphere (TOA) reflectance, required for the atmospheric correction step. I would also recommend at least to set the doGeometryKLT = True, as it is always better to have coregistered pixels when working with time series.
If doFusion = False, then the doPackagerL2F = True is not necessary as the doPackagerL2F is for Landsat-8 fused products (at Sentinel-2 spatial resolution). doPackagerL2H is for harmonised products at native resolution.
Please also have a look to the section 5.2.3 of User Manual and the updated readme on https://github.com/senbox-org/sen2like, concerning the importance of meteorological data when working with this sen2like version:
“(…) It is worth noting that the overall accuracy of your final ARD product strongly depends on the accuracy of sen2like auxiliary data. Two categories of auxiliary data are important: the raster reference for geometric corrections and the meteorological data for atmospheric corrections. Regarding atmospheric corrections, one possibility is to use data from the Copernicus Atmosphere Monitoring Service [9]. The Sen2Like team prepared a dedicated CAMS monthly dataset for the Year 2020, available from here [hyperlink available on github]. Please refer to this short description [hyperlink available on github] for additional information. (…)”
Have a good day working with sen2like!
Sen2Like team
