Fig 1: (A) Schematic of the box model. Boundaries of the box model are selected Mθe surfaces at 15, 30, 45, and 60 Mθe values (1016 kg), which are shown as zonal and 2009 to 2018 averages. (B) Selected near-surface Mθe contours as 2009 to 2018 averages. Mθe is computed from 3-h MERRA-2 reanalysis. These Mθe bands are nearly fixed with season. Red triangles show the location of surface stations that are used in the Carbon Tracker 2019b 3D (three-dimensional) CO2 inversion product.
