Latest Ionogram. Digisonde Scaled Data. Digisonde Scaled Data The HAARP Digisonde includes the ARTIST-4 software component which performs autoscaling of ionograms.

Digisonde Scaled Data

Autoscaling is the process of determining the characteristic parameters of an ionogram, such as foF2 (the F2 layer critical frequency), using software to interpret the reflection layers in the ionogram. A description of the available scaled parameters can be found here . One or more parameters can be selected for display by holding the key while selecting from the list. HAARP VHF Riometer. HAARP VHF Riometer The chart below is a plot of the readings taken using the HAARP VHF Riometer .

HAARP VHF Riometer

This instrument is a sensitive receiver tuned to a frequency of 30 MHz. The antenna is an array of 4 element "yagi" type elements pointed directly upward to listen to the background or galactic noise. This noise varies from one hour to the next as the Earth rotates and, in the absence of ionospheric absorption, is a constant, repeatable function of Local Siderial Time. Over many observations, it is possible to develop a "quiet day" curve which represents the greatest noise that would be heard for any given hour of the day.

Induction Magnetometer. HAARP Magnetometer. HAARP Fluxgate Magnetometer The chart below is a running 36 hour plot of the readings taken from the fluxgate magnetometer, built by the University of Alaska, Geophysical Institute, operating at the HAARP ionospheric observatory in Gakona, Alaska.

HAARP Magnetometer

The three traces represent mutually orthogonal components of the earth's magnetic field as follows: The "H" component (black trace) is positive magnetic northward The "D" component (red trace) is positive eastward The "Z" component (blue trace) is positive downward.
