     Surface methane (CH₄) emissions are derived from atmospheric measurements of methane and its ¹³C carbon isotope content. Different sources of methane contain different ratios of the two stable isotopologues, ¹²CH₄ and ¹³CH₄. This makes normally indistinguishable collocated sources of methane, say from agriculture and oil and gas exploration, distinguishable. The National Oceanic and Atmospheric Administration (NOAA) collects whole air samples from its global cooperative network of flasks (https://gml.noaa.gov/ccgg/about.html), which are then analyzed for methane and other trace gases. A subset of those flasks are also analyzed for ¹³C of methane in collaboration with the Institute of Arctic and Alpine Research at the University of Colorado Boulder. The ground and airborne CH₄ and ¹³CH₄ data used to optimize the methane emissions for CarbonTracker-CH₄ are publicly available by [Lan et al. 2023](https://gml.noaa.gov/ccgg/arc/?id=166). 
 
-    Scientists at NOAA and the National Aeronautics and Space Administration (NASA) used those measurements of methane and ¹³C of methane in conjunction with a model of atmospheric circulation to estimate emissions of methane separated by three source types, microbial, fossil and pyrogenic. Microbial emissions are produced by microbial decomposition of present-day organic matter, such as in wetlands, agricultural fields, livestock and landfills. Fossil emissions come from the breakdown of ancient carbonaceous matter deep underground, such as natural gas, coal bed methane, and small amounts of naturally occurring geologic seeps. Finally, pyrogenic emissions come from the burning of present-day organic matter, such as from wildfires and biofuels. These three sources of methane come with slightly different ¹³C content, and therefore can be separated given enough atmospheric measurements. This dataset presents monthly methane emissions from microbial, fossil and pyrogenic sources, along with a layer of total methane emissions from all three sources combined, at 1° resolution from 1998 to 2021.

     ## Dataset Accuracy
-    Evaluating the accuracy and uncertainty of gridded emissions data is challenging because of the lack of direct physical measurements on grid scales. The emissions presented here were transported by an atmospheric model, and the resulting methane and ¹³C of methane fields were compared to atmospheric measurements of methane and ¹³C of methane globally over multiple decades. Under that transformation and within the bounds of model and observational uncertainty, these emissions satisfy the spatial patterns and time trends seen in the atmospheric measurements. More information about the model-data comparison and evaluation of the model results can be found at: [https://doi.org/10.25925/40jt-qd67](https://doi.org/10.25925/40jt-qd67).

     The atmospheric inverse model was run at 3° (longitude) x 2° (latitude) globally to estimate monthly surface emissions. The atmospheric inversion problem is under-constrained, and therefore inversely estimated emissions cannot be interpreted at the grid scale. Therefore, to present 1°x1° emission maps for the US GHG Center, prior 1°x1° emissions were scaled to match the posterior gridded monthly totals for each source type.
