EarthRef.org Digital Archive (ERDA) -- Geomagnetic field shielding over the last one hundred thousand years

Description
Geomagnetic field cutoff rigidity over the last one hundred thousand years.

Effective vertical cutoff rigidity (in unit GV) Rc100k, from 100 ka BP - 0 ka BP, at time steps of 200 years before 10 ka, and 50 years after 10 ka, global grids 5 deg in latitude and 5 deg in longitude. Latitude grid -85:5:85; Longitude grid 0:5:360; Lines are latitude from -85 to 85 in 5 degree steps; Columns are longitude from 0 to 360 in 5 degree steps
Cutoff rigidity estimates from the models CALS10k.2; GGFSS70; LSMOD.2; and GGF100k are also available in the same format.
