Hello,
I am looking for the latest version of this document:
[L2A-ATBD] Sentinel-2 Level-2A Products Algorithm Theoretical Basis Document
I found a version from 13th April 2011 (Issue 1.8), is this the final version? Do you have a newer report?
Thanks in advance.

Gonçal.

Dear bdpg,

there have been further updates to the [L2A-ATBD] S2PAD-ATBD-0001.pdf document?

because I found discrepancies between the threshold values published from §3.2.4 to § 3.2.6.2 of this document and the one published here: https://sentinel.esa.int/web/sentinel/technical-guides/sentinel-2-msi/level-2a/algorithm
Could you please help me to understand which values should I refer to?

A second question please:
are all the threshold values needed for complete step 5 (§3.2.6) provided?
(“The pixel enters the test only if its value in Band2 is lower than a threshold that varies linearly in function of B2/B11 ratio” and “The pixel enters the test only if its value in Band 12 is lower than a threshold that varies linearly in function of B2/B11 ratio”.

Thanks a lot for your kind attention!
