126Calibration monitoring change: As a major component of TEB F-factor, 'linear slope' trending plots are added in our ICVS-LTM webpage as you see in the plots ( http://www.star.nesdis.noaa.gov/icvs/status_NPP_VIIRS.php ). These 'linear slope' are calculated from the blackbody radiance / (DN_BB-DN_SV). A foot note is added about the 'linear slope'. These trending results are compared with VCST results and validated.2014-06-04 00:00:002014-06-04 00:00:00154

130VIIRS Lunar Calibration: S-NPP will perform a VIIRS Lunar Calibration on 06/09/2014. VIIRS encoder offset and gain will be set for moon observation from 03:42:26 UTC to 03:49:28 UTC. Please note that this month’s cal will NOT require a maneuver.2014-06-09 03:42:262014-06-09 03:49:28159
131The S-NPP VIIRS is scheduled to perform sector rotation for lunar observation in the orbit# 13546 on June 9 to allow the Moon image to be captured in the middle of Earth data sector (target time at 3:48:42z). A roll maneuver is not required this time. During the sector rotation, the VIIRS on-board calibrators and Earth view sectors data are shifted and the dual gain bands are set from Auto Gain mode to fixed High Gain (HG) mode. 4 and a half min VIIRS SDRs/EDRs impacted period: 3:46:27 to 3:50:58z (sector rotation and HG).2014-06-09 03:46:272014-06-09 03:50:58159

133SNPP VIIRS DAS Execution Anomaly notice #1: A new VIIRS DAS was uploaded to NPP on 06/12/2014 14:54 on contact SVL 13595. The first command executed on 2014/06/12 15:01:39.000; the command was to transition VIIRS to Op-Night mode. When that command was executed, VIIRS returned an error VRCPLASTEVWD, which specifies that an invalid stored command was attempting to be executed. The command was executed and VIIRS transitioned to Op-Night and a yellow alarm was triggered on the following contact. Investigating the yellow alarm, is was determined that no further commands are being executed from the VIIRS DAS; thus the instrument remained in Op-Night mode from 2014/06/12 15:01:39.000 on. During contact SVL 13598 at 2014/06/12 19:52:30, VIIRS was ground commanded to Op-Day mode. It is expected that VIIRS will remain in Op-Day mode until a new DAS is uploaded and executing nominally.2014-06-12 14:54:002014-06-12 15:01:12162

135VIIRS TEB quarterly calibration: The VIIRS sensor on Suomi-NPP will be conducting its quarterly emissive band calibration on June 23-25th. Due to the VIIRS blackbody temperature changes during the calibration the VIIRS science data quality may be affected for certain applications, but the data is expected to remain within specification.2014-06-23 00:00:002014-06-25 00:00:00173

138SBC lockup. On 2014-09-26 approximately 16:21:24 UTC VIIRS stopped outputting science data. At 16:41:07 UTC (AOS SVL 15100) controllers reported multiple VIIRS and 1394 bus alarms to engineers. During the back orbit engineering verified the state of the VIIRS instrument and began preparations for recovery. The VIIRS Single Board Computer (SBC) Lock-up recovery is being executed during SVL 15101-15104. During SVL 15101 (18:24:35 - 18:35:07 UTC) VIIRS was power-cycled and science data resumed at approximately 18:35 UTC but may be degraded for multiple orbits. All VIIRS DNB data will be degraded prior to SVL 15104 when the VIIRS DNB tables are expected loaded.2014-09-26 16:21:242014-09-26 23:44:36268
139The S-NPP is scheduled to perform a roll maneuver (-8.982 deg) on Dec 31 for VIIRS lunar calibration in orbit# 16463 with VIIRS sector rotation (encoder offset) to allow the Moon image to be captured in the middle of Earth view sector (target time 19:38:08z). During the sector rotation, the VIIRS calibrators and Earth view sectors data are shifted and the dual gain bands are set from Auto Gain mode to fixed High Gain (HG) mode. 13 min VIIRS SDRs/EDRs impacted period: 19:32:38 - 19:45:39z (sector rotation and HG). 12 min geolocation pointing off nadir: 19:33:08 - 19:45:08z (maneuver).2014-12-31 19:32:382014-12-31 19:45:39364

During the sector rotation, the VIIRS calibrators and Earth view sectors data are shifted to allow the Moon image to be captured in the middle of Earth view sector, and the dual gain bands gain mode will be switched from Auto Gain to fixed High Gain (HG). 13 min VIIRS SDRs/EDRs impacted period: 03:55:35 - 04:08:36z (sector rotation and HG). 12 min S-NPP spacecraft pointing off nadir: 03:56:05 - 04:08:05z (maneuver).2016-05-17 03:55:352016-05-17 04:08:36137
