Research ReportDiurnal global ocean surface pCO₂ and air-sea CO₂ flux reconstructed from spaceborne LiDAR data.

ABSTRACT: The ocean absorbs a significant amount of carbon dioxide (CO₂) from the atmosphere, helping regulate Earth's climate. However, our knowledge of ocean CO₂ sink levels remains limited. This research focused on assessing daily changes in ocean CO₂ sink levels and air-sea CO₂ exchange, using a new technique. We used LiDAR technology, which provides continuous measurements during day and night, to estimate global ocean CO₂ absorption over 23 years. Our model successfully reproduced sea surface partial pressure of CO₂ data. The results suggest the total amount of CO₂ absorbed by oceans is higher at night than during the day. This difference arises from a combination of factors like temperatures, winds, photosynthesis, a
