How leaf area index (TLAI) is calculated from leaf carbon (leafc) in CLM5.0.06

Hi all,

I have a question that how leaf area index (TLAI) is calculated from leaf carbon (leafc) in CLM5.0.06.

Any source code or document that describes the calculation process ?

Sincerely,

It is here in CNVegStructUpdateMod.F90:

! update the leaf area index based on leafC and SLA
! Eq 3 from Thornton and Zimmerman, 2007, J Clim, 20, 3902-3923.
if (dsladlai(ivt(p)) > 0._r8) then
tlai(p) = (slatop(ivt(p))*(exp(leafc(p)*dsladlai(ivt(p))) - 1._r8))/dsladlai(ivt(p))
else
tlai(p) = slatop(ivt(p)) * leafc(p)
end if
tlai(p) = max(0._r8, tlai(p))
