NPPCalc¶

constructor¶

NPPCalc(WELL512 **apWELL)

apWELL

Array of WELL512 random numbre generators.

The constructor stores the random number generators.

destructor¶

virtual ~NPPCalc() {};

The destructor does nothing.

calcNPP¶

virtual double calcNPP(double *dT, double *dP, int iNum, int iStride, double *dOut, double *dVariance=0)=0;

dT

Array of temperatures (average annual temperatures in degrees Celsius).

dP

Array of precipitation values (total annual rainfall in mm).

iNum

Number of element in arrays (dT and dP are supposed to have the same size).

dOut

Output array.

dVariance

Jiggle the result to achieve a certain variance

Fills an array with NPP values (gC/m2/year) calculated from the corresponding elements in dT and dP.

Returns the maximum NPP value found.

This method must be implemented by derived classes.

calcNPP¶

virtual double calcNPP(double dT, double dP, double dVariance=0)=0;

dT

Temperature value (average annual temperature in degrees Celsius).

dP

Precipitation value (total annual rainfall in mm)

Returns an NPP value (gC/m2/year) from the provided Temperature and Precipitation values.

This method must be implemented in derived classes.

calcVariance¶

double calcVariance(double dVariance);

dVariance

Variance for random number
