How to get 10m resolution of sentinel-2？

Hello fsteinmetz！

How to get 10m resolution of sentinel-2？

Regards，

Hello Tian,

To process S2 MSI at 10m, you can pass the argument resolution='10' to Level1_MSI :
run_atm_corr(Level1_MSI(..., resolution='10'), ...)

Cheers,
François

thanks，When I try to run it，I received such mistakes. What should I do？

Hello,
There may have been a temporary network issue. Could you have another try ?
Cheers,

I run it again, successfully. But there is another problem. It stay in this interface all the time(about 20mins).

Hello, I would like to ask how to solve this problem. I have tried to change several networks, but they all meet the same problem？
