Batch Processing Sentinel-2 in l2gen

Wondering if there's a way to batch process multiple Sentinel-2 scenes of different areas in l2gen? Also, is it possible to make l2gen with Sentinel-2 scenes run faster (multiprocessor?).

Thanks!

Masking cloud shadow in l2gen (for Sentinel-2)

Hi All,

What command do I need to mask cloud shadow for S2 images during atmospheric correction - I assume cloud shadow isn't masked by default?

I tried to produce a mask for cloud shadow (l2_flags.LOWLW) but looks like cloud shadow isn't masked at all.

Thanks!

Masking land in Sentinel 2 images

Hi All,
I was trying to put off landmask option in my Sentinel-2 image processing with l2gen via the command line using:

maskland=off

but seems not working as land area is still being masked. Any pointer please?

Using the most updated ancillary data to process Sentinel 2 images with l2gen

Hi All,

Wondering if there's a way to ensure all ancillary data for l2gen processing for Sentinel 2 images are updated for my image (via the command line). I'd like to use ancillary data specific to my image date for a more robust Rrs retrieval.

Thanks.

Default land mask in l2gen for MSI

Hi All,

Looks like the default land mask for Sentinel processing is too course. Some of the pixels have rectangular/square shape along the edges as opposed to the exact shape of land, thus covering some water pixels. Is there a way to correct this, please? Same applies to the default cloud mask.

Thanks.
