Subject: ground-segment-maintenance Impact: data-delayed Detail: McMurdo Security Maintenance. The enhanced timeliness achieved for Metop-B data through the Antarctic Data Acquisition (ADA) system might be interrupted during the following periods: 2018/02/06 between 21:00z and 22:00z, 2018/02/08 between 20:30z and 21:30z, 2018/02/08 between 22:30z and 23:30z and 2018/02/09 between 20:30z and 21:30z. Therefore only nominal Arctic timeliness will be available during this period.
