Hello,
I'm currently processing scenes from both S2 and L8 missions. The only product that I'm trying to generate here is rhos. Since I'm only generating rhos, I expect the process to be decently quick. However, it takes a couple of hours (up to 5 hours) for a single scenes. I know the performance of the single core plays a role here, but the issue here is that the time to produce rhos products on this machine is almost the same as the time to generate Rrs products. I also noticed in the output log that for instance "CHLFAIL" is calculated. Is that necessary for rhos products?

you can set atmocor=0 to disable aerosol calculation.

Thanks Minwei! It actually helped to cut the processing time for a particular test scene from 5 hours to 3 hours.
