7. Relativistic Electron Specification Throughout Inner Magnetosphere: >2 MeV Electron Flux New Product Utilize data and models to specify radial band at all longitudes 3-D grid to low altitudes 5 minute cadence Current Product One value at GOES-East One value at GOES-West 5 minute cadence Benefit: Improved specification of the satellite-charging environment at all longitudes (GEO) and in MEO and LEO, and improved specification of human radiation hazard at International Space Station.

8. Magnetic Field Specification in the Inner Magnetosphere Magnetometers measure the magnitude and direction of Earth’s magnetic field and its variability at geosynchronous orbit. The field is sampled at 2 Hz (threshold) 8 Hz (goal). Current Product One value of field at GOES-East One value of field at GOES-West 0.5 s cadence, accuracy uncertainties New Product Improved accuracy, extrapolation to other geosynchronous locations, and new guidance for forecasters. Benefit: Current product accuracy limited because satellite is spin stabilized and because only two locations are monitored. New product will specify more accurate field and extend to other satellite locations in geosynchronous orbit. Needed for energetic particle trajectories and assessment of geomagnetic disturbances.

10. Solar X-ray flare observations Impact the ionosphere and disrupt radio communications Related to precursors of space weather storms. The value of the XRS is that it continues the same observation that has been made for nearly 30 years. New science applied to the XRS data set will provide new and improved products. Combining GOES and POES data will improve the D-Region Absorption product Advances in science will improve the ability to use X-ray data to predict energetic proton events GOES-R X-Ray Sensor D-Region Absorption Product Combinging GOES and POES data D-Region Absorption Product for HF Propagation Proton Probability Product Using X-ray Temperature Data from GOES

Space Weather Atmosphere Terrestrial Weather Snow Pack Air Quality Estuaries Oceans Fresh Water Coasts Soil Moisture NOAA Observing Systems Architecture (NOSA) and Global Earth Observing System of Systems (GEOSS) Design observing systems that support NOAA's mission and provide maximum value. Space weather observations are integrated into NOSA, including GOES observations that contribute to the global Earth and Solar observations used in NOAA’s operations to continuously specify and forecast conditions in the space environment. Environmental Services NOAA is focused on building “an integrated global environmental observation and data management system”—an Earth observation system that is comprehensive and sustained.
