The relationship between climatic/environmental signals from high resolution snow pit studies and meteorological conditions

Metadata record for data from ASAC Project 1172 See the link below for public details on this project.---- Public Summary from Project ----The aim of ice core drilling is to extract information which aids in the reconstruction of past climatic conditions. There has been limited research, however, towards calibrating records preserved in the ice sheet with atmospheric conditions. The intention of this project is to conduct a detailed study of individual snowfall events in the upper few meters of snow and their relationship with observed meteorological conditions during the events.Na, Ca, Cl, K, Mg are all sea salt indicator species. NO3 is a summer marker (debate exists on the primary source of this species).Work has been carried out over three field seasons to date. 1999/2000, 2001/2002, 2004/2005.The data are held as a series of excel spreadsheets (.xls). The files relate to snow pit and PICO ice core data collected over 2 summers at Law Dome for ASAC 1172. Below is a summary of the spreadsheets.Summer 99/00PICO cores between 3-10m:1181_99bMPCN4kS0kS0p1kS0p3kS0p7kS1p7kS3p7kS7p7kSnow pits to 3m:RamaPaddyKariokeSummer 01/02PICO cores between 3-10m:CC1CC2DSS0102Snow pit to 2.25m:MatildaThe fields in this dataset are:DepthConcentrations of MSA (Methansulphonic acid) Concentrations of Cl Concentrations of NO3 Concentrations of SO4 Concentrations of nss SO4 (non-seasalt sulphate) Concentrations of Na Concentrations of K Concentrations of Mg Concentrations of Ca
