NPP Data Processing

All data that is collected by NPP’s instruments and sensors will be processed into Sensor Data Records (SDRs). Those are used to create EDRs (Environmental Data Records) which are operational data products. CDRs (Climate Data Records) are developed for long term climate and global change studies.

NPP’s data systems are responsible for storing and processing data that is acquired by the instruments. Raw data sent from the intruments are being run through advanced algorithms in order to create high standard data products. Each intrument will provide its measurements in Raw Data Records (RDR) which will then be used to create three different data products: SDRs (Sensor Data Records), EDRs (Environmental Data Records) and CDRs (Climate Data Records). The Interface Data Processing Segment (IDPS) will receive Raw Instrument Data from the spacecraft via ground stations that support the mission. IDPS then removes RDRs from the incoming data stream and processes the result into Sensor Data Records and Environmental Data Records. All three data products will be delivered to two Meteorological Centrals for evaluation, processing and further use in various environmental applications.

IDPS also transmits data to the Archive and Distribution Segment (ADS). ADS is in charge of archiving all IDPS data products and make them available to the public and enable science teams to study archived results. In addition to that, IDPS provides instrument calibration and monitors algorithm performance that generates data products.
