Description

Data on the spatial distribution of transport emissions for CAMS-REG v8.1. Data is available in vector format (em_vkm_vector_dataset.gpkg) and gridded raster format (gridded/ directory) of 0.05° x 0.1° degrees resolution.

The vector dataset includes all information necessary to derive a gridded spatial distribution for different resolutions and extents. Fields include traffic volume, road class, road length, country code, urban/rural/highway category, and total emissions per vehicle type as well as total vkm per vehicle type. Information on each field of the vector file are given in a Readme file (Readme.txt). The raster datasets are Netcdf files, which contain absolute emissions (kg NOX/y) as well as fractions (% NOx emissions of country) for all countries as Netcdf variables.

To facilitate comparisons with city inventories, urban boundaries are provided in a .gpkg file (cities_polygons.gpkg).
