calcGrowingPeriodMonths

Calculates which gridcell-specific months in which growing conditions are favorable for crop growth based on monthly grass GPP

Usage

calcGrowingPeriodMonths(selectyears, lpjml, climatetype, minThreshold = 100)

Arguments

selectyears

Years to be returned

lpjml

LPJmL version required for respective inputs: natveg or crop

climatetype

Switch between different climate scenarios or historical baseline "GSWP3-W5E5:historical"

minThreshold

Threshold of monthly grass GPP to be classified as growing period month Unit of the threshold is gC/m^2. Default: 100gC/m^2 Note: the default value is chosen based on LPJmL version 5 to reflect multiple cropping suitability as shown in GAEZ-4. An update of LPJmL5 with regards to grass management may require an adjustment of the threshold.

Value
