In JGCRI/gcamdata: Build the GCAM Input Datasets

module_aglu_LB163.bio_Yield_R_GLU_irr

Description

Compute base year generic, rainfed, and irrigated bioenergy crop yields for each GCAM region and GLU.

Usage

module_aglu_LB163.bio_Yield_R_GLU_irr(command, ...)

Arguments

command	API command to execute
...	other optional parameters, depending on command

Details

A global average yield is calculated for each GTAP crop. This is then used to calculate a yield Ratio for each iso-GLU-irrigation for each GTAP crop. This ratio and harvested area are then summed across all GTAP crops to the GCAM region-GLU-irrigation level and are used to calculate a YieldIndex for each region-GLU-irrigation. This YieldIndex is then multiplied by a base yield (calculated from USA yields) to get bioenergy yields for each region-GLU-irrigation.

Value

Depends on command: either a vector of required inputs, a vector of output names, or (if command is "MAKE") all the generated outputs: L163.ag_irrBioYield_GJm2_R_GLU, L163.ag_rfdBioYield_GJm2_R_GLU. The corresponding file in the original data system was LB163.bio_Yield_R_GLU_irr.R (aglu level1).
