Methane Measurements at CMERI
Accurate methane measurement is the foundation of effective emissions management. At the Center for Methane Emissions Research and Innovation (CMERI), we focus on developing and deploying advanced measurement techniques to detect, quantify, and track methane emissions across diverse environments. Our research integrates cutting-edge sensing technologies with data analytics to improve methane monitoring capabilities.
Current Research Focus:
Mobile Methane Measurements with sUAS -- Uncrewed Aerial Systems (sUAS) provide a flexible and efficient platform for methane detection. Our work in this area includes: (1) sUAS-mounted sensors for methane emission leak detection and quantification (LDAQ). (2) Advanced flight path optimization for targeted emissions tracking and estimation. (3) Investigation into AI-driven data processing to enhance real-time emission characterization. By deploying drone-based measurement platforms, we can rapidly assess methane sources in remote, industrial, and natural environments.
Methane Signal Retrieval from Satellite Hyperspectral Data -- Satellite-based methane detection is revolutionizing large-scale emissions monitoring. Our research in this domain focuses on: (1) Hyperspectral and multispectral remote sensing for methane column density retrieval. (2) Advanced signal processing algorithms to improve methane detection accuracy. (3) Integration of satellite and aerial data for multi-scale methane mapping. By leveraging space-based observations, we enhance our ability to track methane emissions from both natural and anthropogenic sources across regional and global scales.
Future Directions -- CMERI is expanding its methane measurement capabilities to include: (1) Ground-based mobile sensing, utilizing vehicle-mounted sensors for urban and industrial methane monitoring. (2) Fixed sensor networks, enabling continuous, high-resolution emissions tracking in critical areas. By integrating these technologies, we aim to create a multi-scale, multi-platform methane monitoring system that delivers actionable insights for emissions reduction.
