1091. Simulation direction, 1 for forward, -1 for backward in time
110        (consult Seibert and Frank, 2004 for backward runs)
111
1122. Beginning date and time of simulation. Must be given in format
113   YYYYMMDD HHMISS, where YYYY is YEAR, MM is MONTH, DD is DAY, HH is HOUR,
114   MI is MINUTE and SS is SECOND. Current version utilizes UTC.
115
1163. Ending date and time of simulation. Same format as 3.
117
1184. Average concentrations are calculated every SSSSS seconds.
119
1205. The average concentrations are time averages of SSSSS seconds
121   duration. If SSSSS is 0, instantaneous concentrations are outputted.
122
1236. The concentrations are sampled every SSSSS seconds to calculate the time
124   average concentration. This period must be shorter than the averaging time.
125
1267. Time constant for particle splitting. Particles are split into two
127   after SSSSS seconds, 2xSSSSS seconds, 4xSSSSS seconds, and so on.
128
1298. All processes are synchronized with this time interval (lsynctime).
130   Therefore, all other time constants must be multiples of this value.
131   Output interval and time average of output must be at least twice lsynctime.
132
1339. CTL must be >1 for time steps shorter than the  Lagrangian time scale
134   If CTL<0, a purely random walk simulation is done
135
13610.IFINE=Reduction factor for time step used for vertical wind
137
13811.IOUT determines how the output shall be made: concentration
139   (ng/m3, Bq/m3), mixing ratio (pptv), or both, or plume trajectory mode,
140   or concentration + plume trajectory mode.
141   In plume trajectory mode, output is in the form of average trajectories.
142
14312.IPOUT determines whether particle positions are outputted (in addition
144   to the gridded concentrations or mixing ratios) or not.
145   0=no output, 1 output every output interval, 2 only at end of the
146   simulation
147
14813.Switch on/off subgridscale terrain parameterization (increase of
149   mixing heights due to subgridscale orographic variations)
150
15114.Switch on/off the convection parameterization
152
15315.Switch on/off the calculation of age spectra: if yes, the file AGECLASSES
154   must be available
155
15616. If IPIN=1, a file "partposit_end" from a previous run must be available in
157    the output directory. Particle positions are read in and previous simulation
158    is continued. If IPIN=0, no particles from a previous run are used
159
16017. IF IOUTPUTFOREACHRELEASE is set to 1, one output field for each location
161    in the RLEASE file is created. For backward calculation this should be
162    set to 1. For forward calculation both possibilities are applicable.
163
16418. If IFLUX is set to 1, fluxes of each species through each of the output
165    boxes are calculated. Six fluxes, corresponding to northward, southward,
166    eastward, westward, upward and downward are calculated for each grid cell of
167    the output grid. The control surfaces are placed in the middle of each
168    output grid cell. If IFLUX is set to 0, no fluxes are determined.
169
17019. If MDOMAINFILL is set to 1, the first box specified in file RELEASES is used
171    as the domain where domain-filling trajectory calculations are to be done.
172    Particles are initialized uniformly distributed (according to the air mass
173    distribution) in that domain at the beginning of the simulation, and are
174    created at the boundaries throughout the simulation period.
175
17620. IND_SOURCE switches between different units for concentrations at the source
177    NOTE that in backward simulations the release of computational particles
178    takes place at the "receptor" and the sampling of particles at the "source".
179          1=mass units (for bwd-runs = concentration)
180          2=mass mixing ratio units
18121. IND_RECEPTOR switches between different units for concentrations at the receptor
182          1=mass units (concentrations)
183          2=mass mixing ratio units
184
18522. MQUASILAG indicates whether particles shall be numbered consecutively (1) or
186    with their release location number (0). The first option allows tracking of
187    individual particles using the partposit output files
188
18923. NESTED_OUTPUT decides whether model output shall be made also for a nested
190    output field (normally with higher resolution)
191
19224. LINIT_COND determines whether, for backward runs only, the sensitivity to initial
193    conditions shall be calculated and written to output files
194    0=no output, 1 or 2 determines in which units the initial conditions are provided.
195
19625. SURF_ONLY: When set to 1, concentration/emission sensitivity is written out only
197    for the surface layer; useful for instance when only footprint emission sensitivity is needed
198    but initial conditions are needed on a full 3-D grid
