Understanding the global methane budget represents unique challenges given the large variety of methane sources from thermogenic, biogenic and pyrogenic processes, and given the complexity of methane removal from the atmosphere by a combination of chemical sinks and methanotrophy. Integrating land and atmospheric models with remote sensing and inventory information can help address these challenges to better attribute drivers of interannual and decadal scale trends, constrain uncertainties, and reveal areas for future research. This research opportunity seeks proposals that address natural and/or anthropogenic components of the global methane budget that use modeling, remote sensing, or inventory data to quantify sources or sinks. Empirical, process-based, and box-modeling approaches are included in the possible techniques for addressing and investigating the global methane cycle. In particular, questions related to quantifying methane emissions from oil and gas activities, natural wetlands, agriculture, landfills, and minor sources like termites, wildlife, fire are of interest. The isotopic information of methane is a useful tool for partitioning sources to categories and Earth system models are gradually incorporating isotopes as independent tracers. The time frame of interest can range from pre-industrial to present day, or the past two decades where atmospheric methane concentrations show a period of stability followed by renewed growth, or  the time frame can consider century scale climate feedbacks.
