The record spans from the end of 2004 until the end of 2014 and is comprised of individual sample sets, generally collected in February of each year. Together, they comprise a quasi-monthly record over this time span and in conjunction with Pedro data set (https://data.aad.gov.au/metadata/records/10Be-Law-Dome-10-year-composite), a continuous quasi-monthly record from 2000-2016.

Notes

Purpose
To study, at high temporal resolution, the production and deposition of 7Be and 10Be as the Sun enters new Solar Cycle 24 following the deepest solar minimum in nearly a century. To use the 10Be/7Be ratio to inform on atmospheric pathways, atmospheric residence times and stratosphere / troposphere exchange patterns responsible for 10Be transport and deposition to Law Dome. To further constrain the observed seasonal cycle in 10Be and the timing, pervasiveness and origin of the summer - autumn maximum in 10Be concentration. To quantify climate modulation of 10Be concentrations at Law Dome and so provide guidelines for improving the interpretation of palaeo-solar activity from ice core records of 10Be. To identify short-term spikes in 10Be and 7Be caused by solar proton events (SPE). To continue the master DSS chronology record through collection of a dedicated 5-7 m core for chemical and water isotope analysis.
