particle_ratio: Particle Ratio

In christiaanpauw/AQoffset: Makes calculation needed for air quality offsetting

Description

Calculate the equivalence of sources in terms of the resultant concentrations at each receptor.

Usage

particle_ratio(source1 = NULL, conc1 = NULL, source2 = NULL,
  conc2 = NULL)

Arguments

source1	numeric vector of the same length as nlayers(conc1). Total emissions
conc1	A Raster object giving the concentrations resulting from source1 over the area identified by the raster's origin and extent. Source1 is the source to be offset.
source2	numeric vector of the same length as nlayers(conc2).
conc2	A Raster object giving the concentrations resulting from source2 over the area identified by the raster's origin and extent. Source2 is the offset source (i.e. the source that does the offsetting).

Value

A raster or raster stack with the source equivalence ratios (source impact ratio). A large number means there is a large offset opportunity or that the offset source (source 2) has a much larger impact than the source to be offset (source1).
