Vertical profiles of BrO and aerosols from MAX-DOAS measurements at Arrival Heights

DOI

The data set contains vertical profiles of the bromine monoxide (BrO) mixing ratio and aerosol extinction in the lower troposphere derived from long-term Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) measurement at Arrival Heights, Antarctica (77°49' S, 166°39' E).Reactive halogen compounds, including bromine, have an important impact on the oxidative capacity of the atmosphere. Aerosols, and in particular blowing snow, potentially provide saline surfaces for the release of reactive bromine.Vertical profiles of BrO and aerosols are retrieved from slant column densities of BrO and the oxygen collision complex O4 using the optimal-estimation based HEIPRO algorithm as described in Frieß et al. [2011] (DOI:10.1029/2011JD015938). The data set consists of hourly data from October 2012 to present on a vertical grid with 20 layers of 100 m thickness between the surface and 2 km altitude.Note that a quantitative comparison of this data set with other vertically resolved observations requires the consideration of the MAX-DOAS averaging kernels which are available by the author upon request.
