Class EmissionIndustrialIntensityFunction

java.lang.Object

net.finmath.climate.models.dice.submodels.EmissionIndustrialIntensityFunction

All Implemented Interfaces:

BiFunction<Integer,Double,Double>

public class EmissionIndustrialIntensityFunction
extends Object
implements BiFunction<Integer,Double,Double>

The function that maps \(i, \sigma(t_{i})) \) to \sigma(t_{i+1})), where \( \sigma(t) \) is the emission intensity (in kgCO2 / USD = GtCO2 / (10^12 USD)). The emission intensity is the factor that is applied to the GDP to get the corresponding emissions. The function is modelled as an exponential decay, where the decay rate decays exponentially (double exponential). Note: This is a continuous time version of the function \( \sigma(t) \) from the original model, except that the division by \( (1-\mu(0)) \) is missing here.
