OSCA IOP-1 Summer: Hydrogen Chloride Abundance from HCl-TILDAS Instrument at Manchester Air Quality
Abstract
Hydrogen chloride time series observations (units:ppbv) from the Manchester Air Quality Site (MAQS), University of Manchester, Manchester, UK, during June-July2021. Data were sampled at 3m above ground level by an HCl-TILDAS instrument (manufactured by Aerodyne Research Inc) installed within a shipping container. The HCl-TILDAS is a tunable infrared laser direct absorption spectrometer and works by the principles of infrared absorption spectroscopy. The data was collected as part of the Integrated Research Observation System for Clean Air (OSCA) project winter intensive to investigate the role of chlorine in an urban background environment. John Halfacre and Pete Edwards collected and performed quality control on the data. Data during blanks, calibrations, and internal instrument quality testing has been removed from this data set. Additionally, data for which the spectral fit was deemed poor were also removed.
