Error when processing sunglint correction for S2
Posted: Thu Jul 27, 2023 4:25 pm
Hello Quinten!
I'm testing AC for Sentinel-2 for the black waters of the Negro river, but I'm having an issue when processing sunglint. I ran ACOLITE without the sunglint correction and it worked fine. I'm running it on Ubuntu 20.04 with python 3.11. Here are my settings:
settings = {"s2_target_res": 20,
"l2w_parameters":'rhow_*',
"dsf_residual_glint_correction": True,
"l2w_mask_negative_rhow": False,
"l2w_mask": True,
"l2w_mask_threshold": 0.05,
"l2w_export_geotiff": True}
And here is the error message:
I have also attached the log file. What could be causing this error?
Thank you in advance,
Matheus
