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...

L1 Browser order request fails

Still not working. It's now hanging up at the Earthdata authentication page. It tells me i'm signed in and the application has been approved. Clicking the "Redirect to Application" doesn't help.

Anomalies after gpt reproject of MERIS FRS L2
