TLDR
In this paper, a force-free solution inside an elliptic cylinder for magnetic cloud models was proposed, which may include effects of a flux rope expansion, and a comparison of this new solution with magnetic cloud observations is done for magnetic clouds with flat magnetic field magnitude profiles.About:

Coronal mass ejections and their sheath regions in interplanetary space
TL;DR: This review focuses on the current understanding of observational signatures and properties of ICMEs and the associated sheath regions based on five decades of studies, and specially emphasize the different origin, properties and consequences of the sheaths andICMEs.

TL;DR: In this article, the authors present a discussion of how a magnetic cloud's front boundary is specifically identified in terms of multi-parameter considerations (i.e. any one or more of: increase in B, directional discontinuity, magnetic hole in b, drop in proton plasma beta, B-fluctuation level change, proton temperature drop, etc.).

TL;DR: In this paper, the authors provide a reference for different magnetic field models and reconstruction methods for interplanetary coronal mass ejections (ICMEs) by analyzing 59 ICME events from the Coordinated Data Analysis Workshop (CDAW) list, using four different magnetic fields and reconstruction techniques; force-free fitting, magnetostatic reconstruction using a numerical solution to the Grad-Shafranov equation, fitting to a self-similarly expanding cylindrical configuration and elliptical, non-force free fitting.

TL;DR: The unprecedented multi-viewpoint observations of the Sun from space, enabled by STEREO Ahead/Behind spacecraft in combination with a suite of observatories along the Sun-Earth lines, have provided much more accurate and global measurements of the size, speed, propagation direction, and morphology of CMEs in both 3D and over a large volume in the heliosphere.

Interplanetary magnetic clouds At 1 AU
L. W. Klein,L. F. Burlaga +1 more
TL;DR: The magnetic field geometry in such a magnetic cloud is consistent with that of a magnetic loop, but it cannot be determined uniquely as mentioned in this paper, but it is known that at least one cloud passed the earth every 3 months, and the average expansion speed was estimated to be of the order of half the ambient Alfven speed.

Magnetic field structure of interplanetary magnetic clouds at 1 AU
TL;DR: In this article, a least-squares program was developed to fit magnetic field data within a cloud, while estimating such cloud properties as its size, maximum field strength, and axis inclination.

Magnetic clouds and force-free fields with constant alpha
TL;DR: In this paper, a cylindrically symmetric, constant alpha force-free magnetic field model was proposed to explain the types of variations of the magnetic field direction that are observed as a magnetic cloud moves past a spacecraft.
