COSMIC podTEC

Storm 2015: 073-079

Model: DLR-TOMO

Instrument: podTEC COSMIC-1

VTEC maps

Top panel shows the VTEC values obtained by the podTEC measurements from COSMIC-1. The VTEC values were computed from the COSMIC receiver altitude (~800 km) up to the GPS altitude (~20.200 km).

Bottom panel shows the corresponding VTEC values computed using DLR-TOMO model.

y-axis are related to the magnetic latitude of IGRF.

x-axis are related to the day of year.

Storm event main phase starts in the beginning of DOY 076.

VTEC histogram and correlation

Left panel shows the histogram of error between DLR-TOMO and the VTEC values measured by COSMIC.

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 DLR-TOMO values.
