Attributing this growth rate to specific sources remains challenging because substantial uncertainties remain in the global methane budget. The launch of TROPOMI, with its orders of magnitude more sampling than GOSAT, as well as use of AIRS methane measurements, offers the potential to dramatically reduce and better characterize uncertainties in the global methane budget. The primary sources of ambiguity in global CH4 source and sink estimates – and the attribution of the growth rate to underlying source and sink processes – include the confounding roles of transport and chemistry errors, prior budget assumptions, and uncertainties in sector-specific isotopic CH4 fractions. Fossil and agricultural emissions have increased atmospheric methane from ~750 ppb in pre-industrial times to about ~1900 ppb today, contributing to about a third of the warming since then.

While the current observing system of surface measurements and satellite observations of total column methane from the JAXA GOSAT satellite, and constraints on fire emissions from MODIS And MOPITT, can reduce uncertainty on tropical fluxes as well as the total anthropogenic and wetland emissions, we cannot yet identify with 95% confidence which sector has contributed to rising atmospheric methane concentrations since 2009.

Scientist John Worden of NASA's Jet Propulsion Laboratory in Pasadena, California, and colleagues focused on fires because they're also changing globally.
John R. Worden and 7 co-authors: “Reduced biomass burning emissions reconcile conflicting estimates of the post-2006 atmospheric methane budget,” Nature Communications, 8, 2227 (2017). The area burned each year decreased about 12 percent between the early 2000s and the more recent period of 2007 to 2014, according to a new study using observations by NASA's Moderate Resolution Imaging Spectrometer satellite instrument.
