Incoherent Scatter Radar

Storm 2015: 073-079

Model: TIE-GCM

Instrument: ISR

ISR electron density profiles

Top panel shows the electron density (Ne) values obtained by the ISR (Inchoerent Scatter Radar) measurements at Millstone Hill.

Bottom panel shows the corresponding Ne values computed using TIE-GCM model.

y-axis is related to the altitude.

x-axis is related to the Ne values in terms of log with base 10.

the color shows the daily Ne variation in local time.

Histogram of error and correlation

Left panel shows the histogram of error between TIE-GCM and ISR Ne measurements.

y-axis is related to number of occurrences of a specific error value.

x-axis is the Ne error.

The mean error (µ) and standard deviation of the error (σ) are shown in the top-right side of the plot.

Right panel shows the correlation (r) of the Ne measurements and TIE-GCM values.
