Abstract Combustion-derived black carbon (BC) aerosols accelerate glacier melting in the Himalayas and Tibet (the Third Pole (TP)), thereby limiting sustainable freshwater supplies for billions of people. However, sources BC reaching TP remain uncertain, hindering both process understanding efficient mitigation. Here we present source-diagnostic Δ 14 C/δ 13 C compositions isolated from aerosol snowpit samples TP. For Himalayas, found equal contributions fossil fuel (46±11%) biomass (54±11%)...
ABSTRACT The Tibetan Plateau and its surroundings are known as the Third Pole (TP). This region is noted for high rates of glacier melt associated hydrological shifts that affect water supplies in Asia. Atmospheric pollutants contribute to climatic cryospheric changes through their effects on solar radiation albedos snow ice surfaces; moreover, behavior fates within cryosphere environmental impacts topics increasing concern. In this review, we introduce a coordinated monitoring research...
Abstract Light‐absorbing impurities (LAIs) in snow of the southeastern Tibetan Plateau (TP) and their climatic impacts are interest not only because this region borders areas affected by South Asian atmospheric brown clouds but also seasonal glacier melt from form important headwaters large rivers. In study, we collected surface snowpit samples four glaciers TP June 2015 to investigate comprehensive observational data set LAIs. Results showed that LAI concentrations were much higher aged...
Alpine lake sediments and glacier ice cores retrieved from high mountain regions can provide long-term records of atmospheric deposition anthropogenic contaminants such as mercury (Hg). In this study, eight sediment one core were collected elevations across the Himalaya–Tibet region to investigate chronology Hg deposition. Consistent with modeling results, showed higher accumulation rates in southern slopes Himalayas than those northern recent decades (post-World War II). Despite much lower...
Abstract. Snow cover plays a key role for sustaining ecology and society in mountainous regions. Light-absorbing particulates (including black carbon, organic mineral dust) deposited on snow can reduce surface albedo contribute to the near-worldwide melting of ice. This study focused understanding carbon other water-insoluble light-absorbing Tibetan Plateau (TP). The results found that dust concentrations generally ranged from 202 17 468 ng g−1, 491 13 880 22 846 µg respectively, with higher...
Western China is home to the largest aggregate of glaciers outside polar regions, yet little known about how in this area affect transport and cycling mercury (Hg) regionally globally. From 2005 2010, extensive glacier snow sampling campaigns were carried out 14 snowpits from 9 over western China, vertical distribution profiles Hg obtained. The Total (THg) concentrations ranged <1 43.6 ng L–1, exhibited clear seasonal variations with lower values summer than winter. Spatially, higher THg...
Yak dung is widely used for cooking and heating in Tibet. We measured real-time concentrations of black carbon (BC) fine particulate matter with an aerodynamic diameter 2.5 μm or less (PM2.5) emitted by yak burning six households different living conditions stove types the Nam Co region, observed a much lower average BC/PM2.5 mass ratio (0.013, range 0.006–0.028) from combustion this area than previously reported estimates, ranging between 0.05 0.11. Based on our measurements, estimated fuel...
Abstract. The Tibetan Plateau and its surroundings, also known as the Third Pole, play an important role in global regional climate hydrological cycle. Carbonaceous aerosols (CAs), including black carbon (BC) organic (OC), can directly or indirectly absorb scatter solar radiation change energy balance on Earth. CAs, along with other atmospheric pollutants (e.g., mercury), be frequently transported over long distances into inland Plateau. During last decades, a coordinated monitoring network...
Abstract. Light-absorbing dissolved organic carbon (DOC) constitutes a major part of the in glacierized regions, and has important influences on cycle radiative forcing glaciers. However, few DOC data are currently available from regions Tibetan Plateau (TP). In this study, characteristics medium-sized valley glacier (Laohugou Glacier No. 12, LHG) northern TP were investigated. Generally, concentrations LHG comparable to those other around world. snow pits, surface ice (superimposed ice) 332...
Abstract Greenhouse gases (GHGs) emissions from streams are important to regional biogeochemical budgets. This study is one of the first incorporate stream GHGs (CO 2 , CH 4 and N O) concentrations in rivers Tibetan Plateau. With one-time sampling 32 sites plateau, we found that most were supersaturated with CO O during period. Medians partial pressures (pCO ), pCH pN presented 864 μatm, 6.3 0.25 μatm respectively. Based on a scaling model flux gas, calculated fluxes (3,452 mg-C m d −1 26.7...
Abstract Lakes play an important role in the global carbon cycle, and littoral zones of lakes are potential hotspots greenhouse gas production. In this study, we measured partial pressures dioxide (CO 2 ), methane (CH 4 nitrous oxide (N O) 17 on Tibetan Plateau. The Plateau were supersaturated acted as sources CO , CH N O to atmosphere. average surface lake water 664.8 ± 182.5, 139.8 335.6, 0.3 0.1 μatm, respectively. diffusive fluxes (and uncentainty intervals) these three gases 73.7...
Between November 2005 and 2007, weekly total suspended particle samples were collected at the Nam Co station in inland Tibetan Plateau (TP). Through inductively coupled plasma mass spectrometry, twenty-nine elements analyzed their sources fluxes investigated. Mean elemental concentrations lower than those edge of TP. Some elements, such as Cr, Ni, Cd, Pb, exhibited high enrichment factors (Cr: 22; Ni: 17; Cd: 23; Pb: 9), indicating possible anthropogenic influence this remote region,...
