The international space weather enterprise relies heavily on in situ plasma, particle and magnetic field measurements from U. S. weather satellites. This year marks the 40th anniversary of the launch of the first U. S. geostationary weather satellite (SMS-1), which carried the direct ancestor of the current GOES Space Environment Monitor (SEM) suite. The GOES space weather observations support the issuance of real-time alerts by the NOAA Space Weather Prediction Center (SWPC). The publicly-available archive of space weather observations at the NOAA National Geophysical Data Center (NGDC) includes NOAA geostationary observations since 1974 and POES/MetOp and Air Force DMSP polar-orbiting observations since 1978 and 1982, respectively. This archive supports the retrospective aspect of the space weather enterprise, which includes model development and anomaly resolution efforts. Over the last several years, NGDC has made a concerted effort to improve its data services in cooperation with the broader space weather community. These improvements include (1) taking over the processing of existing products, (2) creating science-quality versions of existing products, (3) developing new products, (4) improving the distribution of these products, and (5) validating products via on-orbit cross-comparisons. Complementing this retrospective role, NGDC is also responsible for the next-generation GOES-R space weather instrument science and is working as part of the GOES-R calibration/validation group to ensure that these new instruments and their products meet NOAA’s requirements. This presentation will survey NGDC’s efforts in each of these areas, including (1) POES/MetOp SEM-2 fluxes and radiation belt indices, (2) GOES fluxes with data quality flags and error bars, (3) in situ products from GOES-R(S,T,U), (4) cooperative distribution efforts with the NASA Space Physics Data Facility (SPDF) and the Space Physics Environmental Data Analysis System (SPEDAS), and (5) inter-calibrations of solar energetic proton fluxes and of magnetospheric electron fluxes.
