partitionNatHerb: Partition Natural Herbaceous Values by Plant Functional Type

In griffithdan/grassmap: Stable Terrestrial Carbon Isoscape Package

Description

This function divides the total natural herbaceous layer into percent C3 and percent C4 natural herbaceous layers based on crossover temperature values, while accounting for mixed dominance grasslands, by a weighted NDVI ratio.

Usage

partitionNatHerb(nat.herb, c3.clim, c4.clim, mixed.clim, mixed.ratio, filename = '', ...)

Arguments

nat.herb	RasterLayer. Per-pixel percentage of natural herbaceous vegetation.
c4.clim	RasterLayer. C4 dominance climate mask. Output of PFTmasks function. PFTmasks[2]
c3.clim	RasterLayer. C3 dominance climate mask. Output of PFTmasks function. PFTmasks[1]
mixed.clim	RasterLayer. Mixed plant functional type dominance climate mask. Output of PFTmasks function. PFTmasks[3]
mixed.ratio	RasterLayer. Plant functional type dominance ratio
filename	Character. Output filename (optional)
...	additional arguments for writing files as in writeRaster

Value

RasterBrick

Layer1	per-pixel percentage of C3 dominant natural herbaceous vegetation over period of interest
Layer2	per-pixel percentage of C4 dominant natural herbaceous vegetation over period of interest
