cropC4_NA: Percent C4 Crop Cover for North America

In rebeccalpowell/grassmapr: Predict C3/C4 Grass Distribution

Description

Gridded percent C4 crop cover layer for North America in the year 2000, aggregated to 10' spatial resolution. Integrates geographic distribution of global agricultural lands (Ramankutty et al. 2008) with distribution of crop types (Monfreda et al. 2008), following rules described in Powell et al. 2012.

Usage

data(cropC4_NA)

Format

An object of class "RasterLayer"; see Raster.
