Optical properties and source apportionment of HULIS in a tropical megacity: Implications for brown carbon dynamics in Bangkok

Key Points

• Brown carbon dynamics are influenced by the optical properties of HULIS in Bangkok, affecting atmospheric conditions.
• The study reports source apportionment findings that show specific contributions of urban emissions and biogenic sources.
• Through observational analysis, the optical properties of HULIS were investigated to understand their environmental impact over time.
• These findings highlight the need for further research to assess the broader implications of HULIS on air quality and climate.
