Atmospheric methane is naturally broken down in the atmosphere by reactions with hydroxyl radicals (OH) formed by ultraviolet radiation. This relationship between the radicals and CH4 supports a more balanced atmospheric methane concentration, protecting the Earth and its life from climate warming. The reduction of OH produced by these activities, which acts as the CH4 or methane cleanser, pushed atmospheric methane to increase during this period. His expertise in artificial intelligence (AI) models revolutionized the study by providing new, innovative ways to monitor global methane emissions. “These next-generation geo-spatial emission models will integrate earth foundation models and physical constraints to conduct near-real-time monitoring of greenhouse gas emissions,” Ouyang said.
