Temporal and spatial distribution of the mid-tropospheric CO₂ concentrations in Malaysia'

Satellite observations of CO₂ offer a unique portunities to improve our understanding of the carbon sources and sinks. Due to the lack of studies of carbon dioxide (CO₂) concentration in this region, we first confirmed the reliability of the mid-tropospheric Atmosphe...
