Dataset Open Access
GCP-GridFED (version 2020.1) is a gridded fossil emissions dataset that is consistent with the national CO2 emissions reported by the Global Carbon Project (GCP). GCP-GridFEDv2020.1 provides monthly fossil CO2 emissions for the period 1959-2019 at a spatial resolution of 0.1° × 0.1°. The gridded emissions estimates are provided separately for fossil CO2 emitted by the oxidation of oil, coal and natural gas, with mixed international bunker fuels considered separately, as well as for the calcination of limestone during cement production. GCP-GridFED also includes gridded uncertainties in CO2 emission, incorporating differences in uncertainty across emissions sectors and countries, and gridded estimates of corresponding O2 uptake based on oxidative ratios for oil, coal and natural gas.
GCP-GridFEDv2020.1 was produced by scaling monthly gridded emissions for the year 2010, from the Emissions Database for Global Atmospheric Research (EDGAR; version 4.3.2; Janssens-Maenhout et al., 2019), to the national annual emissions estimates compiled as part of the 2020 global carbon budget (GCB-NAE) for the years 1959-2019 (Friedlingstein et al., in revision [ESSD]), an update from the 2019 global carbon budget (Friedlingstein et al., 2019). GCP-GridFEDv2020.1 uses a preliminary release of GCB-NAE covering the years 1959-2019; the GCB-NAE data for 2019 is based on data available in June 2020 and the estimates are thus expected to differ slightly from those presented by Friedlingstein et al. (in revision [ESSD]) which uses new data available since June 2020. A planned update (GCP-GridFEDv2020.2) will use the GCB-NAE data published by Friedlingstein et al. (in revision [ESSD]).
A data description article providing the methodology behind this dataset is in revision (Jones et al., in revision [Scientific Data]) and focuses on the previous version (GCP-GridFEDv2019.1), which used the GCP-NAE dataset published by Friedlingstein et al., (2019). There were no methodological changes since GCP-GridFEDv2019.1 (doi:10.5281/zenodo.3958283); that is, GCP-GridFEDv2020.1 is generated by the approach described in Jones et al. (in revision [Scientific Data]) but with updated (preliminary) GCP-NAE data.
The current version is embargoed until 7th December 2020.
