Ionosphere Program at NGDC
The Ionospheric Physics Group of NGDC operates the Ionosphere portion of the World Data Center for Solar-Terrestrial Physics, Boulder, which seeks out and archives data, data products, and information related to the Ionosphere. Though our focus is ever expanding, much of the current effort at NGDC is in the Ionospheric Vertical Incidence Sounding discipline. NGDC is currently leading the effort to collect, quality control, and distribute a unified dataset of vertical sounding scaled parameters using modern internet based dissemination services.

New — In collaboration with members of the Space Weather Prediction Center (SWPC), the Ionospheric Physics Group of NGDC is pleased to announce a prototype of the Forecasting Ionospheric Real-time Scintillation (FIRST) Tool. By monitoring the height rise of the ionospheric F layer near dusk, an evening equatorial scintillation forecast is possible. Presentations will be made at these upcoming workshops: Space Weather Week (Boulder), International Reference Ionoshere (Colorado Springs).
