Ionospheric behavior statistics from the Livingston station

The existing statistics of the Antarctic ionosphere parameters behavior is supplemented by the results from the Livingston station data for the summer periods of 2005–2019, 35 months in total. The climatology of the parameters behavior came to the constancy of the values of the critical frequency foF2 in the local daytime and evening times and significant differences at night, reaching factor 2. The highest values are in December, the lowest in March. For the maximum height hmF2, the spread of values is small. A comparison of the values of foF2 and hmF2 of the IRI model with observational data is carried out. A certain tendency of an increase in deviations with an increase in solar activity was found. For foF2, dispersion σ does not exceed 25%, for hmF2 −17%. The average values for the entire period are: $\vert\Delta \text{foF}2\vert=0.73$ MHz, σ(foF2) =0.86 MHz and 13.6%, $\vert\Delta \text{hmF}2\vert=22.5$ km, σ(hmF2)=27.5 km and 9.65%. These magnitudes are close to those for stations in the northern hemisphere. The possibility of using the total electron content for determining foF2 is shown.
