To see if California's efforts to cut methane gas are working, we need a detailed and up-to-date map of pollution sources. We developed a powerful system that creates this map by combining three different views.


First, we use satellite data for a big-picture scan of the state. Next, we zoom in on cities using ground-based monitors. Finally, we incorporate direct measurements of pollution plumes from specific facilities like landfills and oil and gas operations.


By layering these views, we create a highly detailed, week-by-week map of California's methane emissions, showing where pollution is coming from and how it changes over time.
