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 IRI-2016 model [default options].
y-axis is related to the geographical latitude.
x-axis is related to the day of year.
Storm event main phase starts in the beginning of DOY 076.
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 IRI-2016 model [default options].
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 IRI-2016 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 IRI-2016 values.
