National Geophysical Data Center (NGDC) contributes to the 12th International Geomagnetic Reference Field (IGRF-12) [October 20, 2014]
The NGDC / Cooperative Institute for Research in Environmental Sciences (CIRES) Geomagnetic Modeling Team of Drs. Patrick Alken, Arnaud Chulliat, Stefan Maus, and Manoj Nair developed and submitted candidate magnetic field models to the International Association of Geomagnetism and Aeronomy (IAGA) for the upcoming 12th generation International Geomagnetic Reference Field (IGRF-12). The IGRF is a mathematical model of the Earth's main magnetic field and its annual rate of change, retrospectively updated every five years by IAGA and widely used by the scientific community. IGRF candidate models undergo a rigorous evaluation by the scientific community before generating the final model. The final IGRF-12 model will be released near the end of 2014. Unlike the operational World Magnetic Model (WMM) navigation model coming December 15, 2014, the IGRF has the freedom to change formats and release dates to enable maximum use of available data and modeling capability. NGDC's candidate models are based primarily on magnetic measurements provided by the European Space Agency's Swarm satellite mission, launched in November 2013.

National Geophysical Data Center (NGDC) facilitates collaboration between National Tsunami Warning Center (NTWC) and Center for Operational Oceanographic Products and Services (CO-OPS) [October 14, 2014]
NGDC's Agile Software Team, working closely with water level data manager Aaron Sweeney, is delivering a flow of near-real time tsunami tide gauge data to CO-OPS. The NTWC operates eight tide gauge stations for improved tsunami warning in Alaska. An NGDC web service allows CO-OPS to consume reformatted NTWC data based on station ID and time for display with the 181 CO-OPS tsunami-ready tide stations. A ninth NTWC tide station is expected to come online in late October 2014 and NGDC will also work to provide the same service for the 13 Pacific Tsunami Warning Center stations. NGDC also retrospectively processes and archives NOAA's tide gauge data. This work directly supports data discovery and re-use by the tsunami research community.
