CALS10k.2

This updated version of geomagnetic field description for the past 10 000 years is mainly based on the same data as CALS10k.1b. However, the model offers higher temporal and spatial resolution due to improved uncertainty estimates for the data and calibrations of sediment relative paleointensity. The large-scale field at the core-mantle boundary and the Earth’s surface is described better by this model than by the previous version CALS10k.1b.
