Subject:	anomaly
Impact:		data-unavailable
Detail:		Investigation is on-going. [Rev. 2]: Further
investigations
about potential root causes are on-going. As a consequence, Metop-B
AMSU-A channel 15 (89 GHz) data will remain unusable until further
notice. In the meantime, users are encouraged to assimilate Metop-B MHS
channel 1 measurements, which also provide sensing information in
the 89
GHz frequency range. [Rev. 3]: AMSU-A channel 15 anomaly is also
causing
ATOVS Sounding product degradation.
