1. Ionospheric Digital Database [gov.noaa.ngdc.stp.ionosonde.G01257]
The ionosphere is that part of the Earth's atmosphere that results mainly from the photo ionization of the upper atmosphere. Traditionally, the following ionospheric regions and their approximate ...

2. Photographic Records Showing the Variations of the Virtual Height of Reflection as a Function of the Radio Frequency [gov.noaa.ngdc.stp.ionosonde.G00551]
The standard (analog) ionosonde produces photographic records known as ionograms, which show the variations of the virtual height of reflection as a function of the radio frequency. The frequency ...

3. Solar Features - Solar Flares - SIDS []
A Sudden Ionospheric Disturbance (SID) is any of several radio propagation anomalies due to ionospheric changes resulting from solar or geophysical events.

4. Casey Station GIS Dataset update from various sources [gis17]
The Australian Antarctic Data Centre's Casey Station GIS data were originally mapped from Aerial photography (January 4 1994). Refer to the metadata record 'Casey Station GIS Dataset'. Since then ...

5. Ionospheric dynamics in the polar cap [ASAC_949]
The aim is to measure structure and drift in polar-cap ionospheric layers in order to test current theories and models, identify unexplained behaviour and develop theoretical explanations. The polar ...

6. Worldwide Hourly Values of Ionospheric Characteristics: foF2, M(3000)F2, hF2,FoF1, M(3000)F1, hF, FoE, hE, foE2, hE2, foEs, fbEs, fmI, and FxI [gov.noaa.ngdc.stp.ionosonde.G00004]
The ionosphere is that part of the Earth's atmosphere that results mainly from the ionizing effect of Solar electromagnetic radiation. For poleware latitudes, the ionizing effect of incident energetic ...
