青藏高原及周边碳质气溶胶数据集

本数据集包括青藏高原及其周边共5个采样点碳质气溶胶包括有机碳和黑碳的浓度和空间分布信息。本数据包含的黑碳和有机碳数据采用膜采样，滤膜为石英滤膜，采样器为大流量采样器，切割粒径为总悬浮颗粒物（TSP），每个滤膜采样周期为24h或48h。采用热光法测定其有机碳和黑碳含量，方法检出限分别为0.43和0.12 ug/cm2。此外，还计算了黑碳的吸光参数（MAC）。该数据集将作为青藏高原及其周边区域碳质气溶胶污染状况及背景值的参考数据集。

This dataset contains concentration and spatial distribution data of carbonaceous aerosols (including organic carbon and black carbon) from a total of 5 sampling sites on the Tibetan Plateau and its surrounding areas. The black carbon and organic carbon data were collected via membrane sampling using quartz filters and high-volume samplers, with a cutoff particle size of total suspended particulates (TSP). The sampling duration for each filter is 24 hours or 48 hours. The concentrations of organic carbon and black carbon were determined using the thermo-optical method, with method detection limits of 0.43 and 0.12 μg/cm², respectively. Additionally, the light absorption parameter (MAC) of black carbon was calculated. This dataset will serve as a reference dataset for assessing the pollution status and background levels of carbonaceous aerosols over the Tibetan Plateau and its surrounding regions.
