• Use of POES SEM-2 observations to examine radiation belt dynamics and energetic electron precipitation into the atmosphere (2010, background): “While ICMEs are the main source of geomagnetic storms at solar maximum, the declining and minimum phase of the 11‐year solar activity cycle is characterized by an increase in the occurrence rate of high‐speed (>500 km/s) solar wind‐ streams emanating from coronal holes [ Richardson et al., 2000 ].”
• Influence of the Precipitating Energetic Particles on Atmospheric Chemistry and Climate (2012, background): “…should be higher around solar maximum, while the probability of HSSWS-driven electron precipitation increases considerably when coronal holes extend to low latitudes, such that HSSWS impact on Earth, which occurs most often in the declining phase of the solar cycle (Richardson et al. 2000).”
• Patterns of F2-layer variability (2001, unknown): “For example, Rush and Gibbs (1973) reviewed the status of short-term predictions of radio propagation conditions at midlatitudes by examining the hourly critical frequencies foE ; foF1, and foF2 of the E,F1 and F2 layers.”
• Differences between CME‐driven storms and CIR‐driven storms (2006, background): “Additionally, interaction regions (IRs) that are not 27-day recurring occur throughout the solar cycle [Bobrov, 1983; Richardson et al., 2000], although their geomagnetic effectiveness is weaker on average than is the geoeffectiveness of CIRs.”
• ON THE WEAKENING OF THE POLAR MAGNETIC FIELDS DURING SOLAR CYCLE 23 (2009, background): “The stochastic nature of Deq(t) gives rise to temporary dips in the IMF strength even at activity maximum (see Figure 13(c)); such “Gnevyshev gaps” (Gnevyshev 1967; Storini et al. 1997; Richardson et al. 2000) do not require an actual decrease in the flux emergence rate.”
• Solar and interplanetary sources of major geomagnetic storms during 1996–2002 (2004, methodology): “We extended the period of study made by Richardson et al. [2000] , who studied the geoeffective events during 1997–2000 to 2003.”

• The Heliospheric Magnetic Field (2013, background): “Both |𝐵| and Φ1AU show similar trends, with clear solar cycle variations in phase with the 𝑅 variation (e.g., Slavin and Smith, 1983; Richardson et al., 2000; Smith and Balogh, 2003; Owens et al., 2008a; Zhou and Smith, 2009; Lockwood et al., 2009a).”
• Solar wind drivers of geomagnetic storms during more than four solar cycles (2012, background): “In past studies (Richardson 2006; Richardson et al. 2000, 2001, 2002), we divided the near-Earth solar wind since 1972 into three basic flow types in order to assess, for example, the contribution of each type of solar wind flow to long-term (> ~solar rotation) averages of geomagnetic indices and…”
