Metal ions are key components in atmosphere that potentially affect the optical properties
and photochemical reactivity of atmospheric humic-like substances (HULIS), while this …

China has been performing nationwide social lockdown by releasing the Level 1 response
to major public health emergencies (RMPHE) to struggle against the COVID-19 (SARS-CoV …

Light-absorbing organic carbon (or brown carbon, BrC) has been recognized as a critical
driver in regional-to-global climate change on account of its significant contribution to light …

The light absorption of brown carbon (BrC) makes a significant contribution to aerosol light
absorption (Abs) and affects the radiative forcing. In this study, we analyzed and evaluated …
