Sentinel-3A data unavailability

08 November 2017

Due to Radio Frequency Interference events with other spacecraft on 24 August and 11 and 13 September 2017, some data was lost for Sentinel-3A during the downlink orbits 7914, 8172 and 8194.

The absolute sensing orbits involved were 7913 (relative orbit 240 of cycle 21), 8171 (relative orbit 113 of cycle 22), 8172 (relative orbit 114 of cycle 22) and 8193 (relative orbit 135 of cycle 22).

This impacted the data from the instruments for the following UTC time periods:

  • OLCI - From 17:16:21 to 17:19:21 on 24 August. From 19:25:00 to 19:28:00 on 11 September. And from 07:59:43 to 08:02:43 on 13 September.
  • SLSTR - From 08:17:43 to 08:20:43 on 13 September.
  • SRAL - From 20:17:04 to 20:27:04 on 11 September. And from 08:04:38 to 08:14:38 on 13 September.

Please note that products covering these sensing times might be degraded or missing.
