- Bulk plasma properties at geosynchronous orbit. (2005, result): “Previous investigations by Korth et al. [1999] have shown that plasma sheet access to geosynchronous orbit is statistically well correlated with the Kp index [Bartels et al., 1939], a proxy for the convection electric field strength [see also Thomsen, 2004].”
- An overview of the impulsive geomagnetic field disturbances and power grid impacts associated with the violent Sun‐Earth connection events of 29–31 October 2003 and a comparative evaluation with other contemporary storms (2005, methodology): “[6] A number of recent publications have offered a defense of the value of indices and for detailed analysis of power system impacts using these indices [Oler, 2004a, 2004b; Gholipour et al., 2004; Forbes and St. Cyr, 2004; Thomsen, 2004].”
- EMIC wave activity during geomagnetic storm and nonstorm periods: CRRES results (2010, background): “The shape and phases of the plasmasphere are dominated by convection which is not well described by Sym‐H, and instead better follows the Kp index as this is a good measure of convection [ Thomsen, 2004 ] . Thus our study is considering EMIC waves and their relationship to the magnetospheric current”
- Differences between CME‐driven storms and CIR‐driven storms (2006, background): “Kp is a measure of the strength of convection in the magnetosphere [Thomsen, 2004].”
- A statistical look at plasmaspheric drainage plumes (2008, background): “MBI is an excellent indicator of magnetospheric convection, as is Kp [Thomsen, 2004], but MBI has higher time resolution than the 3-hour Kp index.”
- The Geomagnetic Kp Index and Derived Indices of Geomagnetic Activity (2021, methodology): “Their study is limited to the auroral electrojet currents for Kp ≤ 4 (but according to Table 3, this accounts for >90% of all Kp values) and yields higher QD latitudes for the auroral oval than the electron precipitation data investigated by Thomsen (2004).”
- Geomagnetic storms driven by ICME- and CIR-dominated solar wind (2006, background): “Since Kp is primarily a measure of the magnetospheric convection strength [e.g., Thomsen, 2004], this demonstrates that following the main phase of the CIR-driven storms, the convection is elevated for a longer period.”
