As a result of three planned instrument special operations on the Copernicus Sentinel-3A spacecraft, additional OLCI scientific data over high latitude regions have been acquired for 9 not consecutive sensing orbits.

In this respect the related user products, generated during the UTC sensing time intervals detailed below, have to be considered as tests data with eventually invalid or degraded scientific content:

• 17 February: from 12:59:41 to 13:39.06, from 14:40:40 to 15:40:05 and from 16:21:39 to 17:21:04.
• 20 February: from 15:02:45 to 16:02:09, from 16:43:44 to 17:43:08 and from 18:24:42 to 19:24:07.
• 24 February: from 14:58:32 to 15:57:55, from 16:39:30 to 17:38:53 and from 18:20:59 to 19:19:52.
