Simultaneous measurements of ambient atmospheric black carbon (BC) mass concentrations and radiative fluxes were carried out over Satopanth glacier in the central Himalayas from September 22 to October 2, 2016, as a part of a glacier campaign experiment. The daily mean atmospheric BC concentrations varied between 165 ± 20–263 ± 32 ng m⁻³ with a mean of 199 ± 54 ng m⁻³ during the observational period. The measured average surface albedo was found to be 0.24 ± 0.11 during the entire period of observation. Spectral albedo from Moderate Resolution Imaging Spectroradiometer - Bidirectional Reflectance Distribution Function (MODIS-BRDF) satellite observation and net radiometer derived glacier albedo was found to be in good agreement with a correlation of 0.64 over the region. Concentration weighted trajectory analysis (CWT) over the site indicates a 70% BC transport from the Indo-Gangetic plain, Pakistan, and the Middle East region. BC radiative forcing was estimated using an optical model along with a radiative transfer model. An average BC direct radiative forcing of −5.4 ± 0.25 W m⁻² and 2.4 ± 0.19 W m⁻² was found respectively in the surface and at the top of the atmosphere (TOA) during the experimental period. The estimated average BC induced heating rate was found to be 0.33 ± 0.04 K day⁻¹over the region.

作为冰川运动实验的一部分，2016年9月22日至10月2日，在喜马拉雅山中部的Satopanth冰川上同时测量了大气中黑碳（BC）的质量浓度和辐射通量。每日平均大气BC浓度在165±20–263±32 ng m ^-3之间变化，平均值为199±54 ng m ^-3在观察期。在整个观察过程中，测得的平均表面反照率为0.24±0.11。中分辨率成像光谱仪-双向反射分布函数（MODIS-BRDF）卫星观测和净辐射仪得出的冰川反照率的光谱反照率与该地区的0.64相关性非常一致。站点上的浓度加权轨迹分析（CWT）表明，来自印度恒河平原，巴基斯坦和中东地区的BC运量为70％。BC辐射强迫是使用光学模型和辐射传递模型估算的。平均BC直接辐射强迫为-5.4±0.25 W m ^-2和2.4±0.19 W m ^-2在实验期间，分别在地表和顶部（TOA）中发现了碳。在该区域内，估计的平均BC诱导的平均升温速率为0.33±0.04 K day ^-1。
