source |
Defines LPJmL version for main crop inputs and isimip replacement. For isimip choose crop model/gcm/rcp/co2 combination formatted like this: "yields:EPIC-IIASA:ukesm1-0-ll:ssp585:default:3b" |
climatetype |
switch between different climate scenarios |
refYear |
reference year for calibration |
selectyears |
Years to be returned (for memory reasons) |
cells |
number of cells "magpiecell" for 59199 cells or "lpjcell" for 67420 cells |
multicropping |
Multicropping activated (TRUE) or not (FALSE) and Multiple Cropping Suitability mask selected (mask can be: "none": no mask applied (only for development purposes) "actual:total": currently multicropped areas calculated from total harvested areas and total physical areas per cell from readLanduseLandInG "actual:crop" (crop-specific), "actual:irrigation" (irrigation-specific), "actual:irrig_crop" (crop- and irrigation-specific), "potential:endogenous": potentially multicropped areas given temperature and productivity limits "potential:exogenous": potentially multicropped areas given GAEZ suitability classification) (e.g. TRUE:actual:total; TRUE:none; FALSE) |
refYields |
assumption for baseline yields with respect to multiple cropping (e.g., FALSE: single-cropped LPJmL yields used as baseline to calculate country-level yields, "TRUE:actual:irrig_crop": multicropped yields where LandInG reports current multiple cropping (irrigation- and crop-specific)) |
areaSource |
data source for croparea used in calculation: FAO or LandInG Note: when calibrating multicropped yields, LandInG croparea should be used |
marginal_land |
Defines which share of marginal land should be included (see options below) and whether suitable land under irrigated conditions ("irrigated"), under rainfed conditions ("rainfed") or suitability under rainfed conditions including currently irrigated land (rainfed_and_irrigated) should be used. Options combined via ":" The different marginal land options are:
