Matching the description of the pools that CBM-CFS3 uses. here is a mismatch between the biomass pools in Boudewyn et al and the carbon pools in CBM. The exact combination of the Boudewyn et al biomass pools that correspond to the aboveground live carbon pools ("merch", "other", "foliage") in CBM-CFS3 used in the MS Access environment or GCBM is unclear. In this module CBM pools "merch", "other", "foliage" correspond to Boudewyn biomass pool as described below. This issue is about pointing out that this R-based CBM may be slightly different then CBM used for reporting or in GCBM.
Boudewyn et al pools (all - refer to Fig.3):
eq1 is "biomass merch"
eq2 is "biomass nonmerch"
eq3 is "biomass sap" ("sap" is for saplings)
"totalStemWood" is the sum of eq1, eq2, eq3
"totTree" is total tree biomass
"bark" is total stem bark biomass
"fol" is foliage biomass
"branch" total branch biomass
CBM pools are calculated from the above Boudewyn biomass pools as follows:
"merch" is Boudewyn eq1
"fol" is Boudewyn "fol"
"other" is Boudewyn "branch" + "bark" + eq2 "biomass nonmerch" + eq3 "biomass sap"
