Product Description
See Jones et al. (2021) for a detailed description of this dataset and the core methods used to produce it. Key details are provided below.
GCP-GridFED (version 2023.1) is a gridded fossil emissions dataset that is consistent with the national CO2 emissions reported by the Global Carbon Project (GCP; https://www.globalcarbonproject.org/) in the annual editions of its Global Carbon Budget (Friedlingstein et al., 2023).
GCP-GridFEDv2023.1 provides monthly fossil CO2 emissions for the period 1959-2022 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, international bunkers, and the calcination of limestone during cement production. The dataset also includes the cement carbonation sink of CO2. Note that positive values in GridFED signify a surface-to-atmosphere CO2 flux (emissions). Negative values signify an atmosphere-to-surface flux and apply only to the cement carbonation sink.
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 (see Jones et al., 2021).
Core Methodology in Brief
GCP-GridFEDv2023.1 was produced by scaling monthly gridded emissions for the year 2010, from the Emissions Database for Global Atmospheric Research (EDGAR v4.3.2; Janssens-Maenhout et al., 2019), to the national annual emissions estimates compiled as part of the 2022 global carbon budget (GCP-NAE) for the years 1959-2022 (Friedlingstein et al., 2023).
GCP-GridFEDv2023.1 uses a preliminary release of GCP-NAE covering the years 1959-2022 (timestamp 1st August 2022; an update from Andrew and Peters [2022]). The GCP-NAE estimates for year 2022 are based on data available at the timestamp and the estimates are thus expected to differ somewhat from those that will be presented by Friedlingstein et al. (2023), which will adopt updates to GCP-NAE since the timestamp.
For full details of the core methodology, see Jones et al. (2021).
Changes to the Seasonality of Emissions in GCP-GridFEDv2022.2 onwards
The seasonality of emissions (monthly distribution of annual emissions) for the following countries/sources is now based on the seasonality observed in the Carbon Monitor dataset (Liu et al., 2020; Dou et al., 2022):
Seasonality is determined in the following ways for those countries/sources:
For all countries not listed above and all years 1959-2021, GCP-GridFED adopts the seasonality from EDGAR v4.3.2 (year 2010; Janssens-Maenhout et al., 2019) and applies a small correction based on heating/cooling degree days to account for inter-annual climate variability which effects emissions in some sectors (see Jones et al., 2021).
