Data sets

Sources of Methane Emissions (Vista-LA), South Coast Air Basin, California, USA. V. Carranza, T. Rafiq, I. Frausto-Vicencio, F. M. Hopkins, K. R. Verhulst, P. Rao, R. M. Duren, and C. E. Miller https://doi.org/10.3334/ORNLDAAC/1525

Short summary

We present a GIS-based approach to mapping methane emissions in areas with dense, complex source mixtures. The Vista-LA database classifies >33 000 potential methane-emitting features concentrated on <1% of the land area in California's South Coast Air Basin. The database is used for planning and analysis of atmospheric measurements, including airborne remote sensing campaigns and on-road mobile surveys focused on methane "hot-spot" detection, and development of a regional emissions inventory.
