Earth's Ring-Current Energy from the Dst Index: The Dessler-Parker-Sckopke Relation Applied to Storm Cases

This paper computes earth's ring-current energy from the dst index from stated published inputs, using algebraic relations whose every step is deposited as executable code. Across the cases computed, ring current energy J spans 2.00e+15 to 2.36e+16. The first case gives Dst nT -50; ring current energy J 2.00e+15. The last case gives Dst nT -589; ring current energy J 2.36e+16. The calculations are simulated and computed from the stated assumptions; they are not measurements. Where a comparison against the Aldred Limit density bound is made, the bound values used are 9.72e54 g per cubic centimetre for a neutron carrier and 2.87e48 g per cubic centimetre for an electron carrier, and the size of any separation found is reported plainly, including where the result is that the bound does not constrain the magnetospheric quantity in question.
