In processing OLCI (S3A and S3B) data, I now see ATMFAIL on the northernmost 3 rows of every granule. The only places on these rows where ATMFAIL is not indicated are the columns where NAVFAIL is indicated (columns 0-~150, ~4815-1864). In previous versions, these NAVFAIL columns were listed as CLDICE. However, as far as I can tell, the ATMFAIL rows were not systematically flagged in previous versions (even as recent as V2022.0).
Additionally, if I subset a granule within l2gen (e.g., cut off the northern ~half of the data), I still get ATMFAIL on the now-northernmost 3 rows.
As an example, I downloaded S3B_OL_1_EFR____20221012T142413_20221012T142713_20221012T234532_0179_071_267_2520_PS2_O_NT_003.zip and processed using l2gen with default params (both on V2022.0 and R2022.14).
In the figure below, red=ATMFAIL, green=NAVFAIL, blue=CLDICE, yellow=none_of_these (pseudo band_math: if ATMFAIL then red else if NAVFAIL then green else if CDLICE then blue else yellow). V2022.0 is on top, R2022.14 is on bottom. Note especially the red line at the top of the bottom panel.
- red=ATMFAIL, green=NAVFAIL, blue=CLDICE, yellow=none_of_these
