青藏高原及周边湖芯黑碳历史记录数据集（1853-2015）

黑碳是重要的吸光性物质，对气候变化具有重要的影响。本数据集包含青藏高原和喜马拉雅山南坡6个湖泊（枪勇湖、唐古拉湖、令戈错、然乌湖、Gokyo、Gosainkunda）湖芯黑碳浓度和沉降通量数据。湖信黑碳浓度采用消解-过滤-热光法测定。本数据集为EXCEL文件，可使用EXCEL直接打开。本数据集有助于研究青藏高原和周边地区大气黑碳沉降历史和进一步分析大气黑碳的来源，可作为研究大气黑碳传输和气候效应评价的基础数据。

Black carbon is an important light-absorbing substance that exerts a significant impact on climate change. This dataset contains black carbon concentration and deposition flux data from lake cores of six lakes located on the Tibetan Plateau and the southern slope of the Himalayas: Qiangyong Lake, Tanggula Lake, Lingge Co, Ranwu Lake, Gokyo, and Gosainkunda. The black carbon concentrations in the lake cores were determined via the digestion-filtration-thermal optical method. This dataset is provided as an EXCEL file, which can be directly opened with Microsoft Excel. This dataset facilitates research on the historical atmospheric black carbon deposition over the Tibetan Plateau and its surrounding areas, as well as further analysis of the sources of atmospheric black carbon, and can serve as fundamental data for studies on atmospheric black carbon transport and climate effect assessment.
