The PSG consists of government and contractor staff located at or near the Goddard Space Flight Center. Under the leadership of the Project Scientists, they are responsible for defining NASA’s science needs, generating project documents, and analyzing contractor documents and algorithms.
The ISP was an advisory committee of scientists in universities and government laboratories. They advised the PSG on science priorities, science requirements, reviewed project and IPO documents and developed an initial science strategy for NPP. This group was disbanded prior to the issue of a NASA Reasearch Announcement (NRA) for a science team.
This group developed the the Government Calibration Validation Plan for NPP.
A science team was selected in August 2007. The NPP Science Team is tasked with evaluating the NPP algorithms and providing guidance to NASA on the NPP data products, data processing, and instrument calibration/validation.
