Overview

Raman spectroscopy reveals seasonal shifts in aerosol composition in Doon valley, suggesting impacts of meteorology and emissions.

Key Points

  • Raman spectroscopy detected significant seasonal shifts in aerosol composition, reflecting environmental changes.
  • During April-May, spectra showed strong D and G bands from black carbon, indicating combustion sources.
  • Analysis conducted on total suspended particles gathered during the COVID-19 lockdown highlights stark changes under low-emission conditions.
  • Findings underline the role of atmospheric conditions in influencing aerosol composition, particularly in the Himalayan region.
