361. Simulation direction, 1 for forward, -1 for backward in time
37
382. Beginning date and time of simulation. Must be given in format
39   YYYYMMDD HHMISS, where YYYY is YEAR, MM is MONTH, DD is DAY, HH is HOUR,
40   MI is MINUTE and SS is SECOND. Current version utilizes UTC.
41
423. Ending date and time of simulation. Same format as 3.
43
444. Average concentrations are calculated every SSSSS seconds.
45
465. The average concentrations are time averages of SSSSS seconds
47   duration. If SSSSS is 0, instantaneous concentrations are outputted.
48
496. The concentrations are sampled every SSSSS seconds to calculate the time
50   average concentration. This period must be shorter than the averaging time.
51
527. Time constant for particle splitting. Particles are split into two
53   after SSSSS seconds, 2xSSSSS seconds, 4xSSSSS seconds, and so on.
54
558. All processes are synchronized with this time interval (lsynctime).
56   Therefore, all other time constants must be multiples of this value.
57   Output interval and time average of output must be at least twice lsynctime.
58
599. CTL must be >1 for time steps shorter than the  Lagrangian time scale
60   If CTL<0, a purely random walk simulation is done
61
6210.IFINE=Reduction factor for time step used for vertical wind
63
6411.IOUT determines how the output shall be made: concentration
65   (ng/m3, Bq/m3), mixing ratio (pptv), or both, or plume trajectory mode,
66   or concentration + plume trajectory mode.
67   In plume trajectory mode, output is in the form of average trajectories.
68
6912.IPOUT determines whether particle positions are outputted (in addition
70   to the gridded concentrations or mixing ratios) or not.
71   0=no output, 1 output every output interval, 2 only at end of the
72   simulation
73
7413.Switch on/off subgridscale terrain parameterization (increase of
75   mixing heights due to subgridscale orographic variations)
76
7714.Switch on/off the convection parameterization
78
7915.Switch on/off the calculation of age spectra: if yes, the file AGECLASSES
80   must be available
81
8216. If IPIN=1, a file "partposit_end" from a previous run must be available in
83    the output directory. Particle positions are read in and previous simulation
84    is continued. If IPIN=0, no particles from a previous run are used
85
8617. IF IOUTPUTFOREACHRELEASE is set to 1, one output field for each location
87    in the RLEASE file is created. For backward calculation this should be
88    set to 1. For forward calculation both possibilities are applicable.
89
9018. If IFLUX is set to 1, fluxes of each species through each of the output
91    boxes are calculated. Six fluxes, corresponding to northward, southward,
92    eastward, westward, upward and downward are calculated for each grid cell of
93    the output grid. The control surfaces are placed in the middle of each
94    output grid cell. If IFLUX is set to 0, no fluxes are determined.
95
9619. If MDOMAINFILL is set to 1, the first box specified in file RELEASES is used
97    as the domain where domain-filling trajectory calculations are to be done.
98    Particles are initialized uniformly distributed (according to the air mass
99    distribution) in that domain at the beginning of the simulation, and are
100    created at the boundaries throughout the simulation period.
101
10220. IND_SOURCE switches between different units for concentrations at the source
103    NOTE that in backward simulations the release of computational particles
104    takes place at the "receptor" and the sampling of particles at the "source".
105          1=mass units (for bwd-runs = concentration)
106          2=mass mixing ratio units
10721. IND_RECEPTOR switches between different units for concentrations at the receptor
108          1=mass units (concentrations)
109          2=mass mixing ratio units
110
11122. MQUASILAG indicates whether particles shall be numbered consecutively (1) or
112    with their release location number (0). The first option allows tracking of
113    individual particles using the partposit output files
114
11523. NESTED_OUTPUT decides whether model output shall be made also for a nested
116    output field (normally with higher resolution)
117
11824. LINIT_COND determines whether, for backward runs only, the sensitivity to initial
119    conditions shall be calculated and written to output files
120    0=no output, 1 or 2 determines in which units the initial conditions are provided.
121
12225. SURF_ONLY: When set to 1, concentration/emission sensitivity is written out only
123    for the surface layer; useful for instance when only footprint emission sensitivity is needed
124    but initial conditions are needed on a full 3-D grid
