Model comparisons to GOCE, GRACE and Stella density data, and solar activity as represented by the F10.7 and F30* radio fluxes; F stands for either F10.7 or F30*. The columns respectively describe: the dataset, the time average (〈O/C〉) and the standard deviation (σ (O/C)) of the density ratio, the sum of the unsigned differenced density ratio for the given time interval (∑|Δ(O/C)|), the mean radio flux (〈F〉), its standard deviation (σ F) and the standard deviation of the detrended flux (), obtained by subtracting a 81-day mean.
