Underestimated Dry Season Methane Emissions from Wetlands in the Pantanal.

ABSTRACT: Tropical wetlands contribute ∼30% of the global methane (CH₄) budget. Limited observational constraints on tropical wetland CH₄ emissions lead to large uncertainties and disparities in representing emissions. In this work, we combine remote sensing observations with atmospheric and wetland models to investigate dry season wetland CH₄ emissions from the Pantanal region of South America. We incorporate inundation maps generated from the Cyclone Global Navigation Satellite System (CYGNSS) satellite constellation together with traditional inundation maps to generate an ensemble of wetland CH₄ emission realizations. We challenge these realizations with daily satellite observations for May-July when wetland CH₄ emission predictions diverge.
