Observation‐Based Constraints on Anthropogenic Carbonyl Sulfide Emissions in Southeastern China From High‐Frequency Measurements in Urban Guangzhou
Carbonyl sulfide (COS) is the most abundant sulfur‐containing trace gas in the troposphere and an important tracer of terrestrial gross primary productivity (GPP), but its application is limited by uncertain regional emissions, especially in East Asia. Here we present one year (April 2022–March 2023) of 3‐hourly online...
