Process EDGAR emissions data

The process_edgar() function imports extracted EDGAR gridded emissions files and returns a single SpatRaster object. Raster formats supported by terra::rast() such as NetCDF (.nc, .nc4) and GeoTIFF (.tif, .tiff) are supported.

Usage

process_edgar(path = NULL, extent = NULL, ...)

Arguments

path: character. Directory containing extracted EDGAR raster files or one or more file paths.
extent: numeric(4) or SpatExtent giving the extent of the raster; if NULL (default), the entire raster is loaded.
...: Placeholders.

Value

a SpatRaster object

Note

process_edgar() currently supports gridded raster outputs from download_edgar() such as the default format = "nc". Plain-text EDGAR downloads should be re-downloaded as raster outputs before processing.
