Topic: Delay in production of higher order VIIRS products

Date/Time Issued: January 30, 2018 2040Z

Product(s) or Data Impacted: Higher order VIIRS products

Date/Time of Initial Impact: January 29, 2018 2014Z

Date/Time of Expected End: TBD

Length of Outage: TBD

Details/Specifics of Change: The VIIRS raw data records (RDRs) that are produced while the spacecraft is in darkness are missing a small percentage of data causing IDPS to not automatically produce higher order VIIRS products. After approximately 2 hours the RDRs can be manually processed to produce higher order products. VIIRS and IDPS engineers are troubleshooting.
