abstract = "{We present a refined statistical analysis based on interplanetary
coronal mass ejections (ICMEs) as well as corotating interaction
regions (CIRs) for the time period 2003-2015 to estimate the
impact of different solar wind types on the geomagnetic activity
and the neutral density in the Earth's thermosphere. For the
time-based delimitation of the events, we rely on the catalog
maintained by Richardson and Cane and the corotating interaction
region lists provided by S. Vennerstrom and Jian et al. (2011,
https://doi.org/10.1007/s11207-011-9737-2). These archives are
based on in situ measurements from the Advanced Composition
Explorer and/or the Wind spacecraft. On this basis, we
thoroughly investigated 196 Earth-directed ICME and 195 CIR
events. To verify the impact on the Earths thermosphere we
determined neutral mass densities by using accelerometer
measurements collected by the low-Earth-orbiting satellites
Gravity Recovery and Climate Experiment and Challenging
Minisatellite Payload. Subsequently, the atmospheric densities
are related to characteristic ICME parameters. In this process a
new calibration method has been examined. Since increased solar
activity may lead to a decrease of the satellites orbital
altitude we additionally assessed the orbital decay for each of
the events and satellites. The influence of CIR events is in the
same range of magnitude as the majority of the ICMEs (186 out of
196). Even though, the extended investigation period between
2011 and 2015 has a lack of extreme solar events the combined
analysis reveals comparable correlation coefficients between the
neutral densities and the various ICME and geomagnetic
parameters (mostly >0.85). The evaluation of orbit decay rates
at different altitudes revealed a high dependency on the
satellite actual altitude.}",
