400 and 681 nm peaks for OLCI L2 Rrs retrievals with l2gen
I assume the offset i'm seeing in the attached scatter plot of two Rrs_681 bands created from an OLCI L1B file using SeaDAS 7.4 and SeaDAS v7.5 is related to this bug.Was the fixed for this bug released in any of the recent SeaDAS v7.5 minor level releases? If not, is there any work around. I tr...

Anomalies after gpt reproject of MERIS FRS L2
Thanks Sean.
Is it possible to override the product reader when using gpt? It looks like it may be possible in SNAP but I didn't see anything obvious in SeaDAS.

Anomalies after gpt reproject of MERIS FRS L2
Hi,I just wanted to point out that this problem still exists in v7.5 and is noted with OLCI data also as seen in the attached (left side image) scene from central Florida. NaN's are masked as red. The masking within clouds is OK because the "applyValidPixelExpression" was set when repr...

OLCI mapping offset
I'm seeing offsets in the mapping of OLCI data processed with l2gen from L1B source data. The offset amount varies by day and with elevation but appears to repeat based on the Sentinel-3 27-day orbit cycle.The first attached image shows the L1B and L2 files overlaid with a vector polygon. The ap...
