Abstract

Computed data that was used within the "Reduced Geomagnetic Shielding During the Laschamps Excursion and its Impact on Cosmic-Ray-Induced Atmospheric Radiation" paper. The repository has data for global geomagnetic cut-off maps throughout the Laschamps Excursion event computed using the OTSO tool and the LSMOD.2 paeleomagnetic model. Cut-off computations for two flight paths: Helsinki to Dubai and Helsinki to New York are also computed. Alongside these computations are radiation dose computations under various conditions using the CRAC:DOMO dosimetric tool over the period of the Laschamps Excursion. A gif file showing the variation of the global geomagnetic cut-off over the excursion event is also included as a simple way to show how the magnetic field was disturbed during this period. Two plots showing the computed radiation doses at aviation altitude for the 774 AD ESPE and GLE #5 under modern geomagnetic conditions are also provided.
