### PARAMETERS TO BE SET BY THE USER ################
###############################################################
#
# cycle_start_date = Start date of ensda experiment (forecast
start date in the first cycle)
#
# N_cycles =
Number of data assimilation cycles in current experiment
#
# cycle_interval = Time interval between subsequent
cycles
#
# length_cold_fcst = Length of cold-start forecast (validated at
cycle_start_date)
#
# FREE_FCST = YES or NO .... fcst after data
assimilation
#
# print = output print
label
#
# ens_size = ensemble size (number of degrees of
freedom)
#
# bin_increment = Probability Density Function (PDF) bin increment
#
(bin= [ i - bin_encrement/2., i + bin_interval/2.))
#
# bin_range = Max PDF bin value considered. The
actual range is (-bin_range,0,+bin_range)
#
# ioutmax = Max number of
minimization iterations
#
# LBFGS_pairs = number of pairs (y,s) used in BFGS
minimization algorithm
#
(currently set to 1; if full BFGS algorithm, set to 'ioutmax-1')
#
# minim_alg = minimization algorithm type (5 characters
length)
#
.......... STEEP
#
.......... CONJG
#
.......... QUASN
#
# START = WARM or COLD
#
.......... WARM: start from previous ensemble cycle
