*'''10-11 Dec 2014''' There was a noted degradation in all stats for F17 in this period. Email correspondence from NRL (Ben R. & Steve S.) and FNMOC indicated that F19 data improperly slipped in to the F17 slot. It appears to have been corrected. <strike> on ECMWF's page, but as of writing (AM on Fri 12 Dec), obs2html hasn't passed the point of correction.</strike> | *'''10-11 Dec 2014''' There was a noted degradation in all stats for F17 in this period.

*'''12 Dec 2014''' - There appears to be a data dropoff in these data types beginning 10 December. It could be similar to the dropoff in November 2014 around the same time of the month. The dropoff is also seen in NCEP radiance monitoring but not at ECMWF. Coverage plots show gaps in orbits over various locations (Americas, Asia). 12/11/2014 06z obsplot coverage shows complete coverage of MetOp-A, nearly complete for MetOp-B. | *'''12 Dec 2014''' - There appears to be a data dropoff in these data types beginning 10 December.

*'''24 Dec 2014''' - After the outage mentioned above there were still occasional dropouts of scans for MetOp-B AMSU-A channel 5. The dropouts increased after about 12/16 and the extent of missing brightness temperature increased over the next few days. It looks like this had been corrected on 23 Dec and coverage on 24 Dec 00z appears normal. | *'''24 Dec 2014''' - After the outage mentioned above there were still occasional dropouts of scans for MetOp-B AMSU-A channel 5.

It looks like this had been corrected on 23 Dec and coverage on 24 Dec 00z appears normal. As mentioned above, the data was not lost at the European centers (namely ECMWF and MeteoFrance) so the data is probably recoverable. | ||
