Capsis

The speciesFile is a parameter file for modules relying on the Fire library. It contains all the information to parametrize a species. It can be modified by the user.

The location of the default file is capsis4/data/fireparadox/specieFile for FuelManager and capsis4/data/standfire/specieFile for STANDFIRE

Several record should be set to define a new species. Among them:

• SLA: specific leaf area (m²kg^-1), used to compute Leaf Area Index (LAI)
• CrownGeometry: List of (relative height in crown (% of (H-CBH)), relative width in crown (% of CD)). Eg: {(0,100);(100,100)} is a cylindric crown.

• MVR: mass to volume ratio (kgm^-3)
• SVR: surface to volume ratio (m^-1)
• MC: moisture content (% of water mass over dry mass)

• constantAboveCBH()
• constant()
• aover1plusExpbminuscHRELFromGround(a,b,c): cumulative is a/(1+Exp(b-c*z/H)
• aover1plusExpbminusc1minusHRELFromGround(a,b,c): cumulative is a/(1+Exp(b-c(1-z/H))

• constant()

• Models for height
• aDBHplusb: H(DBH)=a*DBH+b
• aDBHpowb: H(DBH)=a*DBH^b
• minaDBHpowbcDBHplusd: H(DBH)=min(a*DBH^b;c*DBH+d)
• aplusExpbpluscDBHpowd: H(DBH)=a+exp(b+cDBH^d);
• atimes1minusExpbDBHplusc: H(DBH)= a(1.0-exp(bDBH)) + c;

• aDBHplusb: f(DBH, H)=a*CBH+b
• aDBHpowb: f(DBH, H)=a*DBH^b
• aDBHpowbplusc: f(DBH)=a*DBH^b+c
• aH: f(DBH,H)=aH
• aHTresh: f(DBH,H)=if(H<c;aH;bH)
• hover1plusExpaplusbH: f(DBH,H)=H/(1+exp(a+bH))
