Open Geoscience

The investment that national agencies make in geoscience and geospace inquiries span decades and yet the data may remain locked away in a researcher’s closet on fragile CD-R’s or old tapes. Due to the difficulty of geospace remote sensing, numerous open questions exist. When we answer one question, sometimes we get two or four new questions–such is science. This 2006 Dartmouth auroral research slide deck with many still open questions from Dartmouth is a nice starting point for the student thinking about undergraduate or graduate research.

compact auroral observatory — Auroral tomography is used to give high-speed estimates of electron precipitation vs. space and time.

Sondrestrom Radar Staff — Aurora has scales from tens of meters to hundreds of kilometers. This experiment explores those scales simultaneously.

Red Pitaya v1.1 circuit board — Arrays of $300 radars image the ionosphere in 4-D using amateur radio or experimental HF frequencies and very low power pseudonoise waveforms.

Passive FM radar map New England — Ion-acoustic turbulence can be detected using scattering from 100 MHz FM broadcasts as the transmitter, and networks of receivers forming a multistatic radar.
