1) SESAME Advanced Ionospheric Sounder, Key Parameters maxmize
Resource ID:spase://VSPO/NumericalData/SESAME/KeyParameters/AIS/PT900S
Start:1992-09-01 00:00:00 Observatory:SESAME Cadence:900 seconds
Stop:2001-10-17 23:59:59 Instrument:SESAME Advanced Ionospheric Sounder Resource:NumericalData
This set of key parameters from the SESAME (Satellite Experiments Simultaneous with Antartic MEasurements) ground-based experiment contains ionospheric parameters that are derived from quarter-hourly ionograms. The three parameters include the lowest plasma frequency recorded and the highest plasma frequency recorded from the E-region (MHz), and the highest plasma frequency recorded from the F-region (MHz).

This set of key parameters from the SESAME (Satellite Experiments Simultaneous with Antarctic Measurements) ground-based experiment contains H, D, and Z components of the Earth's magnetic field, measuring variation of field relative to an arbitrary baseline. The data is accurate to 1nT, with 1 minute data representing 'spot' values of the 1Hz sampling. Please see reference: Dudeney, J. R. et. al., Satellite Experiments Simultaneous with Antarctic Measurements (SESAME), Space Science Reviews, Volume 71, Issue 1-4, pp. 705-742, 1995.

4) SESAME 30MHz Riometer Array, Key Parameters maxmize

Stop:2001-10-16 23:59:59 Instrument:SESAME Riometer Resource:NumericalData
This set of key parameters from the SESAME (Satellite Experiments Simultaneous with Antarctic Measurements) ground-based experiment contains equivalent overhead absorption data that are measured at 45 degrees to vertical in N,S,E,W directions in an L-shell-aligned coordinate system (ie rotated 17 degrees anti-clockwise from geographic). Preliminary Quiet-Day Curve is used. The data is accurate to 0.05dB, but possible baseline uncertainties of +/-0.5dB; with 1 minute data representing 'spot' values of the 1Hz sampling.
