The dataset contains satellite L* values, last closed drift shell (LCDS) model locations and model magnetic field values for three two day periods covering three different magnetic storms. The periods covered are 27-28 February 2014, 22-23 June 2015 and 14-15 December 2015. The L* values are calculated for electrons with a pitch angle of 90 degrees at the locations of the GOES-13, GOES-15 and HIMAWARI-8 geostationary satellites, using the IRBEM library with the TS05 and TS07 external magnetic field models. Magnetic field values from the models are also included for the GOES-13 satellite during the June 2015 event. LCDS values for each of the periods are included, with two LCDS models based on the TS05 and TS07 field models, and a third LCDS model based particle tracing simulations.
