L2W outputs not including bands 945 and 1373

Post by catherine »

Quinten,

Thanks so much for making this new version of ACOLITE! I am excited to be testing it.

When I run the DSF correction for S2A MSI tiles and specifying rhos_* as an export: (l2w_parameters=rhot_*, rhos_*) for some reason it does not produce the rhos for the 945 and 1373 bands. Is that standard behavior? I am using all the default settings. Those bands are missing both from the geotiffs and in the .nc file.


Thanks!

Catherine

Hi Catherine

Those bands have low atmospheric transmittance (due to water vapour) and are skipped in the calculation of surface reflectance.

<t>Great! That makes sense. Thanks for the quick reply. <br/>
<br/>
Another thing I noticed is that even when I specify the output resolution as 10m (or 20m or whatever), the files that are generated remain in their native resolution (60, 10, and 20m). Does the s2_target_res=XX change the resolution only for some bands? <br/>
<br/>
Thanks again!</t>

Hi Catherine

Do you mean the NetCDF or GeoTIFF outputs? The bands in the NetCDF file should all be at the chosen resolution. I haven't really checked the GeoTIFF files.
