Solar wind—Magnetosphere coupling functions: Pitfalls, limitations, and applications
M Lockwood - Space weather, 2022 - Wiley Online Library
Solar wind‐magnetosphere coupling functions have now been in use for almost 50 years. In
that time, a very large number of formulations have been proposed. As they become …
