MAIN MODIFICATIONS  IBIS (ex: K83)  ibis.veg.soil • nbforc (number of lines - INPUT file) ex: 70080 • imonth0 (initial month - INPUT file) ex: 6 • iday0 (initial day - INPUT file) ex: 30 • altitude • latitude in degrees • type of vegetation (description in initial.f  these types consist of some combination of plant functional types)

• sand and clay (RAWLS et al., 1992; CAMPBELL E NORMAN, 1997)  ibis.infile • iyear0 (initial year of simulation) • nrun (number of years of simulation) • isimveg (choice between static or dynamic vegetation) • isoilforc (choice between static or dynamic soil physics) • dtime (choice of time step, like 30 min or 1h) 

comforc.h (set the INPUT variables) • dimforc (dimension of INPUT data, size of the vector, the value is the same of the nbforc)



initial.f • ztop (canopy height)



canopy.f • za (tower height)



params.soi • soil layer thicknesses (m)  nsoilay (number of soil layers, actually a constant in comsoi.h = 6)



params.veg • beta2 (parameter rooting profile upper canopy, calibrated by Hewlley for differents Amazon sites K83, K67, K34 and RJA)



params.can • Vmax (max Rubisco activity at 15C, at top of canopy, calibrated by Hewlley for differents Amazon sites K83, K67, K34 and RJA) • chs (heat capacities of stems, upper canopy, calibrated by Hewlley for differents Amazon sites K83, K67, K34 and RJA)



coefm - m (coefficients for stomatal conductance relationship, calibrated by Hewlley for differents Amazon sites K83, K67, K34 and RJA)
