Histograms of the F2 peak parameters residuals ΔfoF2 (ΔfoF2 = foF2RO – foF2ionosonde) and ΔhmF2 (ΔhmF2 = hmF2RO – hmF2ionosonde) between collocated COSMIC-2 and ionosonde measurements for (a–b) all regions and (c–f) with a division into low and middle latitudes. Each plot contains information about the mean, standard deviation, RMS error, and total number of matches.
