Trace gases, ranging from carbon dioxide to water vapour, refer to any of the less common gases found in the Earth's atmosphere. Yet, many of these gases are responsible for the greenhouse effect. It's crucial to understand how their chemistry is affected by air-sea fluxes which involve the exchanges of heat, mass and momentum between the atmosphere and the ocean.
For three decades, scientists have looked into the formation of clouds and their double-edged impact on rising temperatures. Clouds cool the planet as they reflect solar energy back into space, but they also intensify warming by trapping the heat and radiating it back to earth. The scientific community has focused on such 'feedback processes' which either enhance (positive feedback) or weaken (negative feedback) the effect of climate change drivers, analysing a complex system of multiple variables. However, it hasn't yet managed to fully quantify the impact.
Issue - Projections - Climate - Change - Team
To address this issue and produce more reliable projections of climate change, a team of scientists, supported by the EU-funded STRATOCLIM project, observed the western tropical Indian Ocean (WTIO) during the summer monsoon period.
In an article published in the Geophysical Research Letters journal, the scientists said the WTIO during the summer monsoon period is one of the world's largest dimethylsulfide (DMS) source regions to the atmosphere. DMS, which originates from phytoplankton – tiny single-celled floating plants that live near the surface of the oceans – is the largest source of sulfur in the atmosphere. For clouds to form, water has to transition from gas phase to liquid. To do that, it adheres to a small particle in the...
