该数据集包含了2021年8月青海格尔木外场试验获取的边界层大气成分廓线数据。观测站点位于格尔木气象局（36.427N, 94.915E）。数据来源于系留气艇携带的观测仪器在地面至1000米内进行的原位观测。原始数据经过质控后平均成20米高度数据。数据集包括：（1）气象参数：温度和相对湿度廓线132条；（2）痕量气体：臭氧廓线102条；（3）大气气溶胶：细颗粒物尺度谱（0.124-2.55 μm）廓线112条，宽粒径范围尺度谱（0.124-32 μm）103条，PM1和PM2.5质量浓度廓线112条，PM10质量浓度廓线103条，5波长（375, 470, 528, 625, 880nm）等效黑碳质量浓度廓线36条。数据可用于青藏高原城市边界层大气成分分析。

This dataset contains boundary layer atmospheric composition profile data obtained from field experiments conducted in Golmud, Qinghai in August 2021. The observation station is located at the Golmud Meteorological Bureau (36.427°N, 94.915°E). The data originates from in-situ observations carried by instruments mounted on tethered aerostats within the altitude range from ground level to 1000 meters. Raw data were quality-controlled and averaged into datasets at 20-meter height intervals. The dataset includes: (1) Meteorological parameters: 132 profiles of temperature and relative humidity; (2) Trace gases: 102 ozone profiles; (3) Atmospheric aerosols: 112 profiles of fine particulate matter size spectra (0.124–2.55 μm), 103 profiles of wide-range size spectra (0.124–32 μm), 112 profiles of PM1 and PM2.5 mass concentrations, 103 profiles of PM10 mass concentrations, and 36 profiles of equivalent black carbon mass concentrations at five wavelengths (375, 470, 528, 625, 880 nm). This dataset can be used for analyses of urban boundary layer atmospheric compositions over the Qinghai-Tibet Plateau.
