Methane detection is a research area focused on developing and improving methods to detect the presence and concentration of methane gas in various environments. Methane is a potent greenhouse gas that is released through natural processes such as decomposition and human activities like agriculture, oil and gas production, and waste management. Accurate and efficient methane detection is crucial for monitoring and mitigating its impact on climate change, as well as ensuring safety in industrial and residential settings. Researchers in this field may employ a variety of techniques, such as gas sensors, satellite remote sensing, and infrared imaging, to detect and measure methane levels in the atmosphere, soil, and water. The development of new technologies and methodologies for methane detection is an ongoing area of interest and importance in the field of environmental science and engineering.
