Data Products
The NPP operational products, RDRs, SDRs and EDRs, for VIIRS, CrIS, ATMS and OMPS will be produced using the Integrated Data Processing Segment (IDPS) resources. Research algorithm Level 1, Level 2 (CDRs) and higher products will be produced at the Science Data Segment (SDS).

Description of Level 1 Products (SDRs/Level 1B):
VIIRS, CrIS, ATMS and OMPS Sensor Data Records (SDRs) are full resolution sensor data that are time referenced, Earth located, and calibrated by applying the ancillary information, including radiometric and geometric calibration coefficients and geo-referencing parameters such as platform ephemeris. These data are processed to sensor units (e.g., radiances). Calibration, ephemeris, and other ancillary data necessary to convert the sensor data back to sensor raw data (counts) are included.

Description of Level 2 (EDR/CDRs) Products:
The NPP Mission will produce a series of Environmental Data Records (EDRs), which are a subset of the NPOESS EDRs. All 29 NPP EDRs will be produced at the IDPS and a subset of these, and potentially other products, will be produced as Climate Data Records (CDRs) at the SDS. These EDRs and CDRs may have different requirements. In the case of operational products, emphasis will be on generating products with a more rapid data delivery that necessarily involves high-speed availability of ancillary data and high-performance execution of the sensor contractors' state-of-the-art science algorithms for civilian and military applications. For climate research products, the requirement of timeliness can be relaxed, thereby allowing for the implementation of complex algorithms using diverse ancillary data. As understanding of sensor calibration issues and radiative transfer from the Earth and Atmosphere improves, algorithms can be improved, and products can be generated via reprocessing.

CDRs will be produced by the NASA NPP science team, which was selected in late 2003.
