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.
