High resolution aerosol data from the top 3.8 ka of the EGRIP ice core
Here we present the high-resolution CFA data from the top 479 m of the East Greenland Ice coring Project (EGRIP) ice core covering the past 3.8 thousand years. The data consists of 1 mm-depth-resolution profiles of calcium, sodium, am- monium, nitrate and electrolytic conductivity as well as decadal...
