*'''19 Nov 2014''' There are increasing mean O-A and O-F values as well as observation errors for GEOS-15 SNDR-D1 channels 3-8, SNDR-D3 channel 8, and SNDR-D4 channel 8. These abnormal values occur after the GEOS-15 Yaw Flip Maneuver between September 23-24, 2014. Here is the note about the maneuver http://www.ssd.noaa.gov/PS/SATS/SPBULL/MSG2651634.01.txt. | *'''19 Nov 2014''' There are increasing mean O-A and O-F values as well as observation errors for GEOS-15 SNDR-D1 channels 3-8, SNDR-D3 channel 8, and SNDR-D4 channel 8.

*'''9 Dec 2014''' Still keeping an eye on this issue. [http://www.ssd.noaa.gov/PS/SATS/MESS/MSG3381438.01.txt New scan mirror emissivity coefficients for GOES-15 Sounder] were to have been installed December 4. According to the announcement: "Upon this changeover users can expect to see small improvement in accuracy of the GOES-15 (GOES-West) Sounder calibrated radiances, most noticeably on channel 8 (11 um band)." | *'''9 Dec 2014''' Still keeping an eye on this issue.

== SSMIS F19 data improperly sneaking in as F17 == | |||
*'''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 on ECMWF's page, but as of writing (AM on Fri 12 Dec), obs2html hasn't passed the point of correction. | |||
