Measurements of atmospheric mercury, trace gases, aerosols, and meteorology at Storm Peak Laboratory, Colorado, in 2021 and 2022

A dual channel system that appears to avoid a low bias, with an oxidized mercury detection limit of 6-12 pg m-3, was deployed alongside a permeation tube-based automated calibrator at Storm Peak Laboratory (latitude 106.744, longitude -40.455, 3210 m above sea level) near Steamboat Springs Colorado, USA, from March through September in 2021 and 2022.  Criteria pollutants, aerosols, and meteorological parameters were also measured.

一款可有效规避低浓度偏差的双通道系统，其氧化汞检测限为6~12 pg·m⁻³，于2021年及2022年3月至9月期间，与基于渗透管的自动校准仪一同部署于美国科罗拉多州斯廷博特斯普林斯附近的风暴峰实验室（Storm Peak Laboratory，地理坐标：纬度106.744，经度-40.455，海拔3210米）。本研究同时测定了标准污染物、气溶胶及气象参数。
