收藏资源简介：
2015年至2020年，青藏高原的15号冰川 （NO.15）、24K冰川（24K）、阿扎冰川（AZ）、措普沟冰川（CPG）、德木拉冰川（DML）、东绒布冰川（DRB）、冬克玛底冰川（DKMD）、敦德冰川（DD）、古里雅冰川（GLY）、红旗拉普冰川（HQLP）、康西瓦河冰川（KXW）、抗物热冰川（KWR）、廓琼岗日冰川（KQGR）、朗阿定日冰川（LADR）、蒙达岗日冰川（MDGR）、木嘎岗穹冰川（MGGQ）、木吉冰川（MJ）、慕士塔格冰川（MSTG）、纳木那尼冰川（NMNN）、尼玛冰川（NM）、怒江源头（NJYT）、帕隆4号冰川（PL4）、羌塘1号冰川（QT）、枪勇冰川（QY）、曲玛冰川（QM）、色齐拉冰川（SQL）、唐古拉龙匣宰陇巴冰川（LXZ）、夏岗江冰川（XGJ）、雅拉冰川（YL）、泽普沟冰川（ZPG）、朱西沟冰川（ZXG）共31条冰川冰雪的理化性质特征，包括DOC、TN及主要阴阳离子浓度（钙离子、镁离子、钾离子、钠离子，铵根离子、氯离子、亚硝酸根离子、硝酸根离子、硫酸根离子浓度）。样品通过0.45微米分子膜过滤后，使用岛津TOC-L仪器检测，离子浓度则通过离子色谱仪检测。指标单位为mg/L，“n.a.”表示低于仪器检测限，“\”表示缺失值。表格中sheet1为“青藏高原冰川雪冰理化性质（2015-2020）”，sheet2为“冰川基本信息”。
This dataset presents the physicochemical characteristics of snow and ice from 31 glaciers on the Tibetan Plateau during 2015–2020. The 31 glaciers are NO.15 Glacier (NO.15), 24K Glacier (24K), Aza Glacier (AZ), Cuopugou Glacier (CPG), Demula Glacier (DML), Dongrongbu Glacier (DRB), Dongkemadi Glacier (DKMD), Dunde Glacier (DD), Guliya Glacier (GLY), Hongqilapu Glacier (HQLP), Kangxiwa River Glacier (KXW), Kangrewure Glacier (KWR), Kuoqionggangri Glacier (KQGR), Langadingri Glacier (LADR), Mengdagangri Glacier (MDGR), Mugagangqiong Glacier (MGGQ), Muji Glacier (MJ), Muztagata Glacier (MSTG), Namunani Glacier (NMNN), Nima Glacier (NM), Nujiang Source (NJYT), Palong No.4 Glacier (PL4), Qiangtang No.1 Glacier (QT), Qiangyong Glacier (QY), Quma Glacier (QM), Seqila Glacier (SQL), Tanggula Longxiazhailongba Glacier (LXZ), Xiagangjiang Glacier (XGJ), Yala Glacier (YL), Zepugou Glacier (ZPG), and Zhuxigou Glacier (ZXG). The measured parameters include dissolved organic carbon (DOC), total nitrogen (TN), and concentrations of major cations and anions: calcium, magnesium, potassium, sodium, ammonium, chloride, nitrite, nitrate, and sulfate. All samples were filtered through 0.45 μm microporous membranes before analysis. DOC and TN were detected using a Shimadzu TOC-L analyzer, while ion concentrations were measured via ion chromatography. All indices are expressed in units of mg/L. The notation "n.a." indicates that the value is below the instrument's detection limit, and the backslash symbol "" denotes missing values. The dataset includes two spreadsheets: Sheet1 is titled "Physicochemical Properties of Glacial Snow and Ice on the Tibetan Plateau (2015-2020)", and Sheet2 is titled "Basic Glacial Information".
