writeClimate.in: Writes the LWF-Brook90 input file Climate.in
In pschmidtwalter/brook90r: Run the LWF-Brook90 hydrological model from within R.

Creates the Climate.in file from daily climate data and vegetation properties, providing some flexibility with regards to radiation (solar radiation or sunshine hours) and precipitation correction

writeClimate.in(dates, tmax, tmin, vappres, wind, prec, globrad, sunhours,
  densef, height, lai, sai, age, latitude, mesfl = rep(0, length(dates)),
  filename = "in/Climate.in", use.sunhours = F,
  richter.prec.corr = F, prec.int = 1, snow.ini = 0, gwat.ini = 0)

`dates`	date sequence with daily resolution.
`tmax`	daily maximum air temperature, °C.
`tmin`	daily minimum air temperature, °C.
`vappres`	daily mean air vapor pressure, kPa.
`wind`	daily mean wind speed, m s^{-1}.
`prec`	daily precipitation, mm d^-1.
`globrad`	solar radiation on the zero plane, MJm^{-2}d^{-1}
`sunhours`	sunshine duration, hours per day
`densef`	canopy density multiplier between 0.05 and 1, dimensionless
`height`	canopy height, m
`lai`	projected leaf area index, m^{2} m^{-2}
`sai`	projected stem area index, m^{2} m^{-2}
`age`	stand age, years
`latitude`	geographic latitude of the simulated site, decimal degrees
`mesfl`	measured stream flow, mm d^{-1}
`filename`	filename for writing. Defaults to '~in/Climate.in
`use.sunhours`	Use sunshine duration hours rather than global radiation?
`richter.prec.corr`	Correct precipitation values for evaporation and wind losses?
`prec.int`	number of precipitation intervals per day. Currently only 1 interval per day is supported.
`snow.ini`	initial amount of snow on the ground, mm water equivalent
`gwat.ini`	initial groundwater storage below soil layers, mm
