Arguments

...

named values to be included in return value

Details

startdate

start date of the simulation.

enddate

end date of the simulation.

fornetrad

use global solar radiation (="globrad") or sunshine duration hours (="sunhour") for net radiation calculation?

prec.interval

number of precipitation intervals per day (default is 1). If prec.interval > 1, a separate file ("in/PRFILE.DAT") has to be provided manually!

richter.prec.corr

correct precipitation data for wind and evaporation losses (not implented yet)

budburst.method

name of method for budburst calculation. If 'constant' or 'fixed', budburst day of year from parameters is used. All other methods calculate budburst day of year dynamically from temperatures, and the method name is passed to the 'start.method'-argument of vegperiod.

leaffall.method

name of method for leaffall calculation. If 'constant' or 'fixed', beginning of leaffall (day of year) from parameters is used. All other methods calculate budburst day of year dynamically from temperatures, and the method name is passed to the 'end.method'-argument of vegperiod.

standprop.input

name of input for longterm (interannual) plant development. 'parameters': yearly values of stand properties height, sai, densef, lai come from parameters, 'table': values come from a table, see 'longtermdev'-argument of Run.B90.

standprop.interp

interpolation method for aboveground stand properties. 'linear' or 'constant', see 'approx.method'-argument of MakeStand.

lai.method

name of method for constructing seasonal course leaf area index development from parameters. Passed to 'method'-argument of MakeSeasLAI.

imodel

name of hydraulic parameterization: "CH" for Clapp/Hornberger, "MvG" for Mualem/van Genuchten

root.method

method name of the root length density depth distribution function. Any of the names accepted by MakeRelRootDens are allowed. Additionally, "soilvar" can be used if the root length density depth distribution is specified in column 'rootden' in the soil-data.frame

humusroots

shall roots be defined for humuslayer? If TRUE, the humus layers will have the same root length density as the uppermost mineral soil layer.

Value

Returns a list of default model control options for use as 'options.b90'-argument in Run.B90.
