gVelocity: Gradient-based Velocity of Climate Change

In babaknaimi/ccm: Climate Change Metrics

Gradient-based Velocity of Climate Change

Description

The method is developed based on Burrow et al. (2011) which is a gradient-based velocity of climate change. Climate velocity can inform conservation planning and action in a warming world.

Distance-based velocity is also implemented in the package and is available through the ccm function.

Examples

filePath <- system.file("external/", package="climetrics") # path to the dataset folder

# read the climate variables using the terra package (you can use the raster package as well):

pr <- rast(paste0(filePath,'/precip.tif'))

#gv <- gVelocity(pr)

#plot(gv, main='Gradiant-based Velocity for Precipitation')
