Carbonaceous matter, including organic carbon (OC) and black carbon (BC), is an important climate forcing agent and contributes to glacier retreat in the Himalayas and the Tibetan Plateau (HTP). The HTP – the so-called “Third Pole” – contains the most extensive glacial area outside of the polar regions. Considerable research on carbonaceous matter in the HTP has been conducted, although this research has been challenging due to the complex terrain and strong spatiotemporal heterogeneity of carbonaceous matter in the HTP. A comprehensive investigation of published atmospheric and snow data for HTP carbonaceous matter concentration, deposition and light absorption is presented, including how these factors vary with time and other parameters. Carbonaceous matter concentrations in the atmosphere and glaciers of the HTP are found to be low. Analysis of water-insoluable organic carbon and BC from snowpits reveals that concentrations of OC and BC in the atmosphere and glacier samples in arid regions of the HTP may be overestimated due to contributions from inorganic carbon in mineral dust. Due to the remote nature of the HTP, carbonaceous matter found in the HTP has generally been transported from outside the HTP (e.g., South Asia), although local HTP emissions may also be important at some sites. This review provides essential data and a synthesis of current thinking for studies on atmospheric transport modeling and radiative forcing of carbonaceous matter in the HTP.

喜马拉雅山和青藏高原大气和冰川中的碳质:调查综述

碳质物质,包括有机碳(OC)和黑碳(BC),是重要的气候强迫剂,有助于喜马拉雅山和青藏高原(HTP)的冰川退缩。HTP——所谓的“第三极”——拥有极地以外最广泛的冰川区域。尽管由于高温TP地区地形复杂且碳质时空异质性强,该研究一直具有挑战性,但对高温TP中碳质的研究已经进行了大量的研究。对已发表的 HTP 碳质浓度、沉积和光吸收的大气和雪数据进行了全面调查,包括这些因素如何随时间和其他参数变化。高温TP 的大气和冰川中的碳质浓度较低。对雪坑中不溶于水的有机碳和BC的分析表明,由于矿物尘埃中无机碳的贡献,HTP干旱地区大气和冰川样本中OC和BC的浓度可能被高估。由于高温TP 的偏远性质,在高温TP 中发现的碳质物质通常是从高温TP 之外(例如南亚)运输的,尽管本地高温TP 排放在某些地点也可能很重要。这篇综述为高温TP中碳质物质的大气传输模型和辐射强迫的研究提供了必要的数据和当前思想的综合。
