Gridded inventory of Canada's anthropogenic methane emissions for 2018

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.
