The Visible Infrared Imaging Radiometer Suite (VIIRS) is one of the key instruments onboard the Suomi NPP
spacecraft. To ensure the data quality of the VIIRS for all users and products, and to support the calibration/validation of
the VIIRS, a calibration knowledgebase has been developed as part of the cal/val tool for the postlaunch verification and
validation of VIIRS SDR and its use for data quality assurance, anomaly investigation, and EDR applications. The
components of the knowledge-base include 1) event log database which keeps record of all major changes and activities
in both spacecraft flight, and ground processing system, including such events as lunar maneuvers, calibration updates
and anomalies in the processing systems, and instrument performance anomalies such as scan sync loss; 2) VIIRS image
gallery, which has a large sample of VIIRS images for areas of interest such as hurricanes, solar eclipse; 3) validation
site time series which provides long term trending at more than 30 vicarious sites worldwide; 4) daily orbital track which
is used for locating data granules based on the time, location, and orbit. In addition, all VIIRS related parameters and
information are also provided. The Calibration Knowledge base has become an indispensable tool for VIIRS data users.
