三极冰芯数据集（1968-2015）

三极冰芯数据主要来源于美国国家海洋与大气局（NOAA： National Oceanic and Atmospheric Administration, https://www.ncdc.noaa.gov/data-access/paleoclimatology-data/datasets/ice-core ）。原始数据主要是文本格式，由相关单位与研究人员志愿提供。数据主要包含了氧同位素、温室气体浓度、冰芯年龄、等原始观测数据，也包含研究者根据观测数据生产的历史气温、二氧化碳浓度、甲烷浓度等。数据主要分为南极、北极、格陵兰岛及第三极区域。数据库包含打钻地址、时间、衍生产品、对应观测站点数据、参考文献等要素。衍生产品包含产品名称、类型、时间等要素。空间位置分为南极、北极、第三极，包含阿拉斯加、加拿大、俄罗斯、格陵兰岛等地区。对收集的数据通过整理与后处理后，采用Microsoft Office自带的Access数据库管理系统建立冰芯数据库。按照南极、北极、格林兰岛、第三极，分成四个子数据库，打开每个数据库中第一个表为readme，该表包含每个数据表信息及参考文献。

The three-pole ice core dataset is primarily sourced from the U.S. National Oceanic and Atmospheric Administration (NOAA: National Oceanic and Atmospheric Administration, https://www.ncdc.noaa.gov/data-access/paleoclimatology-data/datasets/ice-core). The raw data is predominantly in text format, voluntarily contributed by relevant institutions and researchers. The dataset encompasses original observational data including oxygen isotopes, greenhouse gas concentrations, and ice core ages, alongside derived indicators such as historical air temperatures, carbon dioxide concentrations, and methane concentrations generated by researchers based on the observational data. The data is categorized into four main regions: Antarctica, the Arctic, Greenland, and the Third Pole region. The database includes key elements such as drilling sites, collection time, derived products, corresponding observation station data, and reference literature. Derived products contain attributes including product name, type, and temporal coverage. The spatial scope covers regions including Alaska, Canada, Russia, and Greenland, with the overall spatial divisions being Antarctica, the Arctic, and the Third Pole. Following the organization and post-processing of the collected data, an ice core database was established using Microsoft Access, the built-in database management system of Microsoft Office. It is split into four sub-databases corresponding to Antarctica, the Arctic, Greenland, and the Third Pole. The first table within each sub-database is the readme table, which contains information about each data table and relevant references.
