Replication data for: Trends and seasonality of 2019–2023 global methane emissions inferred from a localized ensemble transform Kalman filter (CHEEREIO v1.3.1) applied to TROPOMI satellite observations

This dataset contains the following: Posterior best estimate methane emissions at monthly 2°x2.5° resolution for 2019-2023, produced in this work (posterior_best_ estimate_ch4_emis.nc). "Total" refers to the total emissions excluding soil absorption (i.e. this is not a flux). Source disaggregation is equivalent to the paper and includes the subgrid correction.

Global 3-D monthly mean OH fields from GEOS-Chem, scaled so that methane's lifetime due to loss to tropospheric OH matches the best estimate of 11.2 years derived from methyl chloroform observations (OH_3Dglobal.geos5.47L.4x5.SCALED.nc).
