grid_to_basin_yield: grid_to_basin_yield

In JGCRI/osiris: Process climate impacts on agricultural yields for GCAM

grid_to_basin_yield

Description

Function that uses emulators to create gridded yield files then aggregates to gcam basin level via MIRCA harvested areas.

Usage

grid_to_basin_yield(
  carbon = NULL,
  weight_floor_ha = 100,
  emulator_dir = NULL,
  input_dir = NULL,
  area_dir = NULL,
  basin_grid = NULL,
  basin_id = NULL,
  region_id = NULL,
  gridded_yield_dir = NULL,
  write_dir = "step2_grid_to_basin_yield",
  wheat_area = NULL,
  crops = c("Corn", "Rice", "Soy", "Spring Wheat", "Winter Wheat"),
  esm_name = "WRF",
  cm_name = "LPJmL",
  scn_name = "rcp8p5_hotter",
  N = 200
)

Arguments

carbon	Default = NULL
weight_floor_ha	Default = 100 Floor on area weights, in hectares. Below this climate impacts will be ignored. These are more likely than others to be problematic. 1 hectare = 0.01 km^2 = 1e-5 thou km^2, GCAM land units
emulator_dir	Default = NULL
input_dir	Default = NULL
area_dir	Default = NULL
basin_grid	Default = NULL
basin_id	Default = NULL
region_id	Default = NULL. Filters to specified GCAM region (1-32), otherwise no filter
gridded_yield_dir	Default = NULL.
write_dir	Default = "step2_grid_to_basin_yield". Output Folder
wheat_area	= NULL
crops	Default = c("Corn", "Rice", "Soy", "Spring Wheat", "Winter Wheat")
esm_name	Default = 'WRF'
cm_name	Default = 'LPJmL'
scn_name	Default = 'rcp8p5_hotter'
N	Default = 200. Assuming nothing is nitrogen limited and apply across grids
