Science Overview

Earth Data

NOAA’s JPSS satellite mission provides critical environmental satellite data to support NOAA’s mission to understand and predict changes in weather, ocean, coasts and climate. The JPSS Program Science provides oversight of the mission’s scientific integrity and user readiness through stewardship of JPSS user requirements, evaluation of scientific performance of JPSS products, and user engagement to assess the impact of JPSS products on user applications (e.g. weather forecasting, harmful algal bloom alerts), continues to support NOAA’s critical product and services. The JPSS Program Science, working with NESDIS STAR , OSGS, and OSPO, and JPSS Flight Instrument Scientists, encompasses:

The JPSS Senior Project Scientist and the Deputy Senior Project Scientist, who also serves as the JPSS Flight Project Scientist, coordinates prelaunch instrument activities. Each of the JPSS instruments has an instrument Scientist working with the JPSS Flight Project Instrument. The Instrument Scientists coordinates the following activities; requirements review and analysis, test plan review and analysis, independent test data analysis, special test data analysis, and independent verification of critical instrument performance requirements. They are also responsible for additional analyses required by data users not provided by instrument vendor and pre-launch analyses for the acceptance or rejection of performance waivers. The Instrument Scientists coordinate with STAR Sensor Data Records (SDRs) Team Leads for SDR Team analysis support, provides JPSS Ground System with specific JPSS-1 instrument data needed for SDR algorithms pre-launch and post-launch, provides JPSS Mission Ops Team with on-orbit calibration maneuver scheduling and execution details, post-launch instrument calibration support, and post-launch instrument anomaly support.
