The Space Environment Monitoring package for the NPOESS (SEM-N) will provide several key Environmental Data Records (EDRs) used for producing operational space weather products by the USAF and NOAA. The ground algorithms used to process sensor Raw Data Records (RDRs) into the space environment EDRs are strongly based on heritage capabilities from DMSP and POES as well as other relevant NASA missions. This talk will discuss the status of the science algorithm development for NPOESS space EDRs, requirements for SEM-N RDRs and other ancillary data, and plans for the operational deployment of the EDR ground processing algorithms.
