carbonHWP — carbonHWP • magpie4

reads carbon stored in harvested timber out of a MAgPIE gdx file

Usage

carbonHWP(
  gdx,
  file = NULL,
  level = "cell",
  unit = "element",
  half_life = 35,
  cumulative = FALSE,
  baseyear = 1995
)

gdx: GDX file
file: a file name the output should be written to using write.magpie
level: Level of regional aggregation; "cell", "reg" (regional), "glo" (global), "regglo" (regional and global) or any secdforest aggregation level defined in superAggregate
unit: element" or "gas"; "element": co2_c in Mt C/yr, n2o_n in Mt N/yr, ch4 in Mt CH4/yr; "gas": co2_c Mt CO2/yr, n2o_n in Mt NO2/yr, ch4 in Mt CH4/yr
half_life: Half life in years for decay in wood products loosing half theor carbon content. (35 yrs is deafault)
cumulative: Logical; Determines if cHWP emissions are reported annually (FALSE) or cumulative (TRUE). The starting point for cumulative emissions is y1995.
baseyear: Baseyear used for cumulative emissions (default = 1995)

carbon stocks in MtC from harvested timber

Annual (and cumulative) Carbon stored in harvested wood products as well as slow emissions from half life deacy.
