DurenarXiv preprint https://arxiv.org/abs/2505.21806Code repository: https://github.com/JPLMLIA/operational-ghg Summary This repository contains the ML-ready datasets used to train methane plume detection and delineation models from the AVIRIS-NG and EMIT missions. These are 256x256 pixel tiles sampled from the columnwise matched filter methane retrieval flightlines and scenes. Please refer to the above manuscript for complete details. COVID.tar COVID_train.csv, COVID_test.csv - tiles and labels for the training and test sets, respectively. COVID/ang*.tif - GeoTIFF tiles of methane retrieval concentrations of plumes and background COVID/ang*_label.tif - PNG corresponding binary masks produced as described in the manuscript CACH4.tar Same as above with CACH4 prefixes Permian.tar Same as above with Permian prefixes multicampaign.tar This dataset contains only the combined train/test dataset definitions that include all three above datasets. EMIT.tar Same as the AVIRIS-NG dataset with EMIT prefixes Acknowledgements The Earth surface Mineral dust source InvesTigation (EMIT) plume delineations were performed using a tool built with the Jet Propulsion Laboratory Multi-Mission Geographical Information System.
