These two parameters are chosen as they characterise the ambient solar wind well, representing both the plasma flow and the large-scale heliospheric magnetic-field structure. In this study we examine 25 years of near-Earth in situ solar-wind observations and 45 years of observation-constrained solar-wind simulations to determine how much the 1-AU solar-wind speed, \(V\), and radial magnetic-field component, \(B_\). Similarly, assimilation of solar-wind observations into models requires quantitative knowledge of how the reliability of the observations changes with age.

Models of the global corona and heliosphere typically assume that the ambient solar-wind structure is steady and corotates with the Sun, which is generally expected to be more valid at solar minimum than solar maximum, but this has not been well tested. Quantifying the rate at which the large-scale solar-wind structure evolves is important for both understanding the physical processes occurring in the corona and for space-weather forecast improvement.
