EarthRef.org Digital Archive (ERDA) -- Global Data Compilation of Archeomagnetic and Paleomagnetic Data, 5000 BC to 1950 AD

Description
A global dataset of archeomagnetic and paleomagnetic data covering the past 7000 years has been compiled. It consists of 16085 results of inclination, 13080 of declination and 3188 of intensity for the time span 5000~BC to 1950~AD. Declination and inclination data partly come from existing databases and partly from original literature. A new global compilation of intensity data for the millennial scale is included. Data and dating uncertainties are discussed as we attempted to obtain an internally coherent dataset. The global distribution of the data is very inhomogeneous
in both time and space. All the data are compared to predictions from the previous 3000 year global model, CALS3K.1. This collection of data will be useful for global secular variation studies and geomagnetic field modeling, although southern hemisphere data are still underrepresented.
