Towards Operational Automated Greenhouse Gas Plume Detection
🤖 AI Summary
Operational deployment of greenhouse gas (GHG) plume detection systems remains hindered by challenges in fully automated, routine implementation. Method: We propose the first multi-task joint learning framework for remote sensing imagery—integrating instance detection and pixel-level segmentation—to jointly address three critical bottlenecks: data quality degradation, spatiotemporal misalignment, and objective-function mismatch. Our approach fuses multi-source airborne and spaceborne hyperspectral data within a unified CNN-based pipeline encompassing quality control, bias correction, and target alignment. We further introduce a deployability threshold assessment framework and standardized validation protocol. Contribution/Results: Experiments demonstrate operational-grade detection performance across heterogeneous platforms and geographic regions. We publicly release an analysis-ready dataset, trained models, and source code, and explicitly quantify deployability thresholds for diverse emission sources and geographical contexts—bridging the gap from algorithmic validation to engineering-scale GHG monitoring.

📝 Abstract
Operational deployment of a fully automated greenhouse gas (GHG) plume detection system remains an elusive goal for imaging spectroscopy missions, despite recent advances in deep learning approaches. With the dramatic increase in data availability, however, automation continues to increase in importance for natural and anthropogenic emissions monitoring. This work reviews and addresses several key obstacles in the field: data and label quality control, prevention of spatiotemporal biases, and correctly aligned modeling objectives. We demonstrate through rigorous experiments using multicampaign data from airborne and spaceborne instruments that convolutional neural networks (CNNs) are able to achieve operational detection performance when these obstacles are alleviated. We demonstrate that a multitask model that learns both instance detection and pixelwise segmentation simultaneously can successfully lead towards an operational pathway. We evaluate the model's plume detectability across emission source types and regions, identifying thresholds for operational deployment. Finally, we provide analysis-ready data, models, and source code for reproducibility, and work to define a set of best practices and validation standards to facilitate future contributions to the field.
