In this file, we include the data from the GCB2022 inversions on 1x1 degrees lat-lon. The data has been adjusted to facilitate comparison with bottom-up estimates. This adjustment includes 3 aspects (fossil fuel, cement sources and sinks, lateral river fluxes): - Fossil fuel and cement adjustment to account for minor remaining differences to GridFED v2022_2 (this GridFED version includes emissions from cement production and a sink from cement carbonation). - Lateral river flux adjustment as provided by Ronny Lauerwald (The file is based on GlobalNEWS2 for organic C and the weathering CO2 sink after Harmann et al. 2009 as used in Zscheischler et al 2017. But in this version, the organic C loads after GlobalNEWS are twice rescaled: 1) to the latitudinal pattern from Resplandy et al. (2018 NatGeo) and 2) to a synthesis of global estimates of organic C exports of about 500 Tg C/yr (for this you could for the time being cite Regnier et al. 2013, Nat Geo).)
