| Typically multi-spacecraft missions are ideally suited to the study of shock
spatial scales due to the separation of temporal and spatial variations.
These missions are not possible at all locations and therefore
in-situ multi-spacecraft measurements are not available beyond the
Earth. The present paper presents a study of shock spatial scales using
single spacecraft measurements made by the Venus Express spacecraft. The
scales are determined based on previous knowledge of shock overshoot scales
measured by the ISEE and Cluster missions. The study encompasses around 60
crossings of the Venusian bow shock from 2006 to 2009. The statistical
relationship between the shock ramp spatial scales, overshoot and upstream
shock parameters are investigated. We find that despite somewhat different
solar wind conditions our results are comparable with those based on
multi-spacecraft missions at the terrestrial bow shock. |
