Scale-dependent processes drive spatially discontinuous methane emissions from small cascade reservoirs

Key Points

• Methane emissions exhibit spatial discontinuity across small cascade reservoirs and hydrological features.
• Key evidence shows that emissions can vary significantly at different scales, impacting local atmospheric conditions.
• Observational analysis on hydrological dynamics in cascade reservoirs reveals important scale-dependent processes.
• These findings highlight the need for comprehensive assessments of methane outputs in various hydrological environments.
