Here we present a gridded inventory of Canada's 2018 anthropogenic methane emissions at 0.1 x 0.1 degree. National and provincial emission totals in the inventory match Canada's National Inventory Report (2020) used for reporting greenhouse gas emissions to the United Nations Framework Convention on Climate Change (UNFCCC). This dataset includes separate gridded inventory files for each emission sector and subsector as shown in Table 1 and Table 2 of Scarpelli et al. [2021]. Emissions are allocated to sources on the 0.1 x 0.1 degree grid using a collection of national and provincial geospatial datasets, and incorporates point source emissions as reported in Canada's Greenhouse Gas Reporting Program (GHGRP) in 2020. All gridded emissions files are at 0.1 x 0.1 degree resolution and reflect 2018 annual emissions, though emissions can be readily updated to other years by scaling total emissions using Canada's annually reported National Inventory Report (NIR). There is a netCDF file for each emission sector. Each netCDF contains gridded variables for (1) total sector emissions with the extension "(total)", (2) corresponding subsector and source type emissions, and (3) latitude/longitude centers and area of each grid cell. Codes used to represent sectors and subsectors follow the definitions in Canada's 2020 NIR.
