Reconciling the bottom-up and top-down estimates of the methane chemical sink using multiple observations

Abstract trop - M ∼ 10 × 10 5 - 3 2 × 10 5 - 3 trop - M - 1 - 1 - 1 trop - M and methane chemical loss simulated by the atmospheric chemistry models is caused primarily by the models' underestimation of carbon monoxide and total ozone column, and overestimation of nitrogen dioxide. Our results highlight that constraining the model-simulated OH fields with available OH precursor observations can help improve bottom-up estimates of the global methane sink.
