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.

y-axis are related to the geographical latitude.
x-axis are related to the day of year.
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.
