Raman spectra of atmospheric particles measured in Maryland, USA over 22.5 h using an automated aerosol Raman spectrometer

•Raman spectra (RS) of atmospheric aerosol particles were measured with a semi-continuous system.•Of the 100,320 RS measured in 22.5 h, approximately 9000 had intensities above the thresholds.•RS were consistent with soots, carbonates, silicates, sulfates, iron oxides and biomaterials.•RS consistent...
