When running getanc with an output path that contains a relative directory, for example: getanc L1B/PACE_OCI.20240913T030441.L1B.V3.nc \ -o anc/PACE_OCI.20240913T030441.anc getanc fails with: FileNotFoundError: [Errno 2] No such file or directo...

I am working on monitoring floating macroalgae (Ulva prolifera) and would like to use Rayleigh-corrected reflectance (Rrc(λ)) instead of the fully corrected remote sensing reflectance Rrs(λ). As pointed out by Chuanmin Hu , aerosol or other atmospheric corrections can fail for pixels containing U. p...
