Launched into orbit on March 4th, 2024, MethaneSAT is the first satellite developed and funded by an environmental nonprofit organization. It is the only methane-detecting satellite that sees the whole picture, measuring methane emissions from millions of small sources around the world that are a huge part of the problem. It has one purpose- to speed up reductions in methane emissions as quickly as possible, so we can slow down global warming. During our Public Preview, MethaneSAT data are freely available via request so that companies, governments, and advocates can speed up emissions cuts, track progress, and hold polluters truly accountable. MethaneSAT LLC is a wholly owned subsidiary of Environmental Defense Fund.
Users who are interested in downloading the data directly rather than exploring through Earth Engine may do so through Google Cloud Platform, where we have the same underlying datasets available.
You will need to apply for use of this data to access on both Google Earth Engine and Google Cloud Platform via this form. See the dataset Terms of Use for more information.

MethaneSAT L3 Concentration Public Preview V1.0.0
This early "Public Preview" dataset provides geospatial data for the column-averaged dry-air mole fraction of methane in the atmosphere, "XCH4", retrieved from measurements by the MethaneSAT imaging spectrometer. XCH4 is defined as the total column amount (number of molecules above a unit surface area) of … atmosphere climate edf edf-methanesat-ee emissions ghg -
MethaneSAT L4 Area Sources Public Preview V1.0.0
The dispersed area emissions model is still in development and not representative of a final product. This early "Public Preview" dataset provides high precision data for methane emissions over wide areas from the oil and gas sector. This includes total emissions that come from discrete … atmosphere climate edf edf-methanesat-ee emissions ghg -

MethaneSAT L4 Point Sources Public Preview V1.0.0
The methane emission fluxes were produced using a point source detection and emissions quantification framework specialized to exploit the high spatial resolution, wide spatial coverage, and high precision of MethaneSAT data (methodology is described in Chulakdabba et al. (2023).) The point source quantification framework was … atmosphere climate edf edf-methanesat-ee emissions ghg
