The Carrington Event not observed in most ice core nitrate records
[1] The Carrington Event of 1859 is considered to be among the largest space weather events of the last 150 years. We show that only one out of 14 well-resolved ice core records from Greenland and Antarctica has a nitrate spike dated to 1859. No sharp spikes are observed in the Antarctic cores studi...

[1] The Carrington Event of 1859 is considered to be among the largest space weather events of the last 150 years.
