|
Years |
years to calculate |
decaydistribution |
decay distribution to use. Defaults to exponential distribution. |
halflives |
data frame of half lives to use. Must have a column associated with each one of 13 end uses and half life values for 1900 until the maximum year of interest. |
paperHL |
half life value for paper |
approach |
approach to calculate corresponding final variables for. If null, all final variables are calculated and returned. |
fsp |
Fraction of structural panel products that go to each end use. Default can be substituted with data with a column for each end use and row for years from 1900 to latest year of interest. |
fnsp |
Fraction of non-structural panel products that go to each end use. Default can be substituted with data with a column for each end use and row for years from 1900 to latest year of interest. |
fsawn |
Fraction of sawnwood products that go to each end use. Default can be substituted with data with a column for each end use and row for years from 1900 to latest year of interest. |
woodToCarbon |
Conversion factor to convert oven-dry tons of solid wood to Tg of Carbon. |
paperToCarbon |
Conversion factor to convert oven-dry tons of paper to Tg of Carbon. |
swpSwdsNondegradable |
Percent of solid-wood products in landfills and dumps that are not subject to decay. |
paperSwdsNondegradable |
Percent of paper products in landfills and dumps that are not subject to decay. |
swpLandfillDecay |
Decay rate of solid-wood products in landfills as a half-life in years. |
paperLandfillDecay |
Decay rate of paper products in landfills as a half-life in years. |
swpDumpDecay |
Decay rate of solid-wood products in dumps as a half-life in years. |
paperDumpDecay |
Decay rate of paper products in dumps as a half-life in years. |
swpdata |
Optional argument to provide swp production and trade time series for purposes of error analysis |
All units are in Gg Carbon.
Var1A = Annual Change in stock of HWP in use form consumption
Var1B = Annual Change in stock of HWP in SWDS from consumption
Var2A = Annual Change in stock of HWP in use produced from domestic harvest
Var2B = Annual Change in stock of HWP in SWDS produced from domestic harvest
Var3 = Annual Imports of wood, paper products, wood fuel, pulp, recovered paper, roundwood/chips
Var4 = Annual Exports of wood, paper products, wood fuel, pulp, recovered paper, roundwood/chips
Var5 = Annual Domestic Harvest
Var6 = Annual release of carbon to the atmosphere from HWP consumption (from fuelwood & products in use and products in SWDS)
Var7 = Annual release of carbon to the atmosphere from HWP (including fuelwood) where wood came from domestic harvest (from products in use and products in SWDS)
If an approach is specified then only the variables needed for that approach will be returned. If approach is null then a data frame with nine columns (Variables 1 and 2 have two parts each) will be returned. If the decay distribution is exponential then the data frame returned will correspond to table containing final variables: '06 IPCC Tables' in the WOODCARB II spreadsheet.
