This project is a continuation of the development of the Rice Field Model (RFM). The RFM is a physical model of the magnetic and electric fields in the magnetosphere. A number of simplifying assumptions were made in developing the current version of the RFM. This new program will improve the accuracy and flexibility of the RFM by removing some of those original assumptions. In particular, the revisions will allow the length of the Earth's magnetotail to be a variable function of the cross-tail potential drop, the assumption that the magnetosphere is in a steady state will be relaxed, and the electric field at the tail X-line will be incorporated as an independent boundary condition. The goal is a more accurate representation of the nightside magnetosphere.

该项目是稻田模型（RFM）开发的延续。 RFM是磁层中磁场和电场的物理模型。 在制定当前版本的区域财务机制时作出了一些简化假设。 这个新的程序将通过删除一些原始假设来提高RFM的准确性和灵活性。 特别是，修订将允许地球磁尾的长度是一个跨尾电位降的可变函数，磁层处于稳定状态的假设将被放宽，并且尾部X线处的电场将被纳入作为一个独立的边界条件。 目标是更准确地表示夜侧磁层。
