An example of the format of a file from which parameter values are read in:

.true. -0.02 0.006 -0.00868
.true. -4.0e-5 4.0e-5 1.42e-5
.true. 0.002 0.008 0.00320
.true. 0.002 0.013 0.0104
.true. -0.2 1.8 -0.18
.true. 0.0 1.0 0.0345
.false. 0.0 1.0 0.8
.false. 0.0 1.0 0.0
.false. 0.0 1.0 1.0

for each parameter give whether it should be optimized, its likely minimum and maximum values and its initial value. When a parameter is not to be optimized, the initial value will be fixed for the duration of the model run and the minimum/maximum range are ignored

In this case the order of parameters are:

  1. lapserateartm
  2. lapserateprcp
  3. pddfs
  4. pddfi
  5. rainsnowtrans
  6. wmax
  7. fiddle
  8. offsetartm
  9. offsetprcp


lapserateartm

Air temperature lapse rate. The rate at which air cools with a change in elevation.


lapserateprcp

Precipitation lapse rate. The rate at which precipitation changes with elevation.
