## Science-related Advisory Groups

**(Internal) NPOESS Science Team – reports to Northrop Grumman **
**(External) NPOESS Science Advisory Board (Joe Friday, chair) - reports to Northrop Grumman**
**Integrated Weather Product Test Bed Team – oversees Raytheon IDPS – reports to Northrop Grumman**
**Instrument Cal/Val Teams – reports to Northrop Grumman & IPO**
**Operational Algorithm Teams (8) – reports to IPO**
**Data Archive Board– reports to OSDPD**

## Some Typical User Questions

**How do I access specific products, whether in real time or after the fact?**
**How can I influence the generation of new products?**
**Where do I go when I think the algorithms, calibration, and/or sensor isn’t working properly?**
**How can I get a long-term data record (i.e., for climate) reprocessed, especially when it spans several satellites?**

## RecommendationNPOESS User Advisory Team of the NOAA Science Advisory Board

_**Suggested Terms of Reference:**_
**Provide guidance and advice concerning the overall performance of the NPOESS system from the user perspective, including:**
**ease of access to existing data & products **
**need for new and/or improved products **
**both research and operational perspectives**

## Back Up

## NPOESS Responsibilities Include: Interface Data Processing Segment

**Product generation subsystems**
**Ingest: Receives SMD, auxiliary, and ancillary data and creates RDRs**
**Processing: Receives RDRs from Ingest, produces TDRs, SDRs, and EDRs**
**Data Delivery: Receives RDRs, TDRs, SDRs, and EDRs from Data Management, aggregates and reformats into HDF 5, and provides to the Centrals, Cal/Val, ADS/CLASS, and SDS via a file transfer or common disk services**
**Product quality, calibration, and validation subsystem**
**Cal/Val: Provides for daily monitoring of product quality, generation of calibration coefficients, and validation of product science**
**Centrals have control over what products are created, which ancillary data sets are used, and how products are delivered**

## NESDIS Responsibilities

**Identify and acquire new data processing and dissemination systems to ensure environmental data can be acquired, processed, distributed to users and archived during the NPOESS era**
**Ensure NESDIS continues to meet existing user requirements and provides continuity of service during the transition from the current POES program to NPOESS**
**Maximize the risk reduction benefits made available by the NPOESS Preparatory Project (NPP)**
