Table 2 Observed δNmF2 = NmF2 Qday/NmF2 ref, observed EUV along with inferred EUV fluxes, vertical plasma drift W, hmF2, atomic oxygen concentration at 300 km in a comparison to MSISE00 model values, and exospheric temperature Tex for negative Q–disturbance and reference days. Numbers in brackets are Q–disturbance day/Reference day ratios. Available Swarm (10−16), GOCE (10−14) and CHAMP (10−15) neutral gas densities at the satellite height are given in the last column. Dashes - observations are absent.
