Altimeter

Storm 2017: 248-254

Model: NEDM

Instrument: Altimeter

VTEC maps during the satellite rising phase

Top panel shows the VTEC values obtained by the altimeter measurements.

Bottom panel shows the corresponding VTEC values computed using NEDM model.

y-axis is related to the geographical latitude.

x-axis is related to the day of year.

VTEC maps during the satellite setting phase

Top panel shows the VTEC values obtained by the altimeter measurements.

Bottom panel shows the corresponding VTEC values computed using NEDM model.

y-axis is related to the geographical latitude.

x-axis is related to the day of year.

VTEC histogram and correlation

Left panel shows the histogram of error between NEDM and altimeter VTEC measurements.

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

x-axis is the VTEC 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 VTEC measurements and NEDM values.
