Antarctic surface snow and ice isotopic dataset

We have established a most comprehensive, reasonable, and quality-controlled Antarctic surface snow and ice isotopic dataset product using a plenty of scientific literature, strict quantitative criteria were designed for the inclusion of records in the database, focusing on recently published records and optimizing data spatial coverage.本团队构建了一套兼具全面性、合理性且经过严格质量管控的南极地表雪冰同位素数据集产品。该数据集依托海量科学文献完成构建，为数据库收录数据制定了严格的量化筛选标准，重点纳入近期发表的观测记录，并优化了数据的空间覆盖范围。
