A new quantitative model of the global shape of the neutral sheet in the Earth's magnetosphere is developed, parameterized by the dipole tilt, solar wind pressure, and IMF By and Bz. The model is based on data from the Polar, Cluster, Geotail, and Themis satellites taken in 1995-2013. The paper quantifies and further explains our earlier finding of the bowl-shaped deformation of the neutral sheet due to the Earth's dipole tilt (Tsyganenko and Andreeva, GRL, v.41(4), 2014).
We explore two new modifications of the magnetotail magnetic flux calculation algorithm based on the pressure balance approach for the tail radius determination. The new modifications extend the scope of the algorithm to the inner magnetosphere, which is possible due to the approximate uniformity of the magnetic field of external sources. A new empirical formula for the tail radius at the terminator is also presented.
