Monthly Mapping of China’s Sectoral CO₂ Emissions at 1 km Using Earth Observation Settlement Products and Emission-Source Infrastructure Zongyao Sha (11781752) Ping Yan (24929151) Greenhouse gas inventories and fluxes carbon dioxide Earth observation data fusion spatial downscaling sectoral emissions <p dir="ltr">This dataset provides monthly, sector-resolved fossil-fuel CO₂ emissions for China from January 2000 to December 2024 at a spatial resolution of 1 km. It contains two components: (A) 300 monthly six-band GeoTIFF files and (B) national-, provincial-, and prefecture-level emission tables at monthly and annual temporal resolutions.</p><p dir="ltr">Each GeoTIFF contains six emission sectors in a fixed band order: power, industrial combustion, buildings, transport, fuel exploitation, and industrial processes. The rasters use the World Equidistant Cylindrical projection (EPSG:6933) with 1000 m × 1000 m grid cells. Emissions are expressed as Mg CO₂ cell⁻¹ month⁻¹, and cells outside the Chinese national boundary are assigned a NoData value of −9999.</p><p dir="ltr">The dataset was produced using a sector-specific, mass-conserving spatial allocation framework. EDGAR provides the controlling sectoral and monthly emission totals, while Earth observation-derived settlement products, the ODIAC fossil-fuel spatial prior, geolocated emission-source infrastructure, population, built-up surface, and road-network information provide sector-dependent spatial evidence. Provincial power emissions for 2000–2022 additionally incorporate a soft constraint derived from the Carbon Emission Accounts and Datasets database. All spatial allocation procedures preserve the prescribed sector-month emission masses.</p><p dir="ltr">The accompanying tabular data (B) report emissions by sector and as six-sector totals at national, provincial, and prefecture levels. The tables are supplied in CSV format and are intended to support temporal analysis, regional comparisons, atmospheric-model input preparation, and evaluation of subnational emission patterns.</p><p dir="ltr">This product is a spatially allocated bottom-up emission inventory. It is not a direct satellite retrieval of atmospheric CO₂ and should not be interpreted as uniformly validated at the individual 1 km grid-cell level. Spatial reliability differs among sectors; users should consult the accompanying documentation, quality-control records, and validation results when selecting an appropriate spatial scale for analysis.</p> 2026-09-15T00:00:00Z Dataset Dataset 10.6084/m9.figshare.33779689.v2 https://figshare.com/articles/dataset/Monthly_Mapping_of_China_s_Sectoral_CO_Emissions_at_1_km_Using_Earth_Observation_Settlement_Products_and_Emission-Source_Infrastructure/33779689 CC BY 4.0
