Attribution of interminima changes in the global thermosphere and ionosphere

We present a statistical attribution analysis of the changes in global annual average thermospheric mass density and ionospheric total electron content (TEC) between the cycle 22/23 solar minimum (which occurred at epoch 1996.4) and the prolonged cycle 23/24 minimum (2008.8). The mass density data are derived from orbital drag, and the TEC data are derived from ground-based GPS receivers. The interminima change in mass density was -36\% relative to the 1996.4 yearly average. Considering each multiplicative forcing indepen ...

A study of the strong linear relationship between the equatorial ionization anomaly and the prereversal EXB drift velocity at solar minimum

It is known that there exists a linear relationship between the maximum velocity of the prereversal enhancement (PRE) of the EXB drift and the strength of the equatorial ionization
