`tratio`	The advection stability ratio. By default, this is set to `0.75`.
`initd`	The initial distribution. Set to `0` by default.
`kpuff`	The horizontal puff dispersion growth. Setting to `0` results in linear growth whereas option `1` uses an empirical growth scheme. By default, this is set to `0` (linear growth).
`khmax`	The maximum duration (in hours) for a particle or trajectory. This is set to the absolute maximum by default, which is `9999` hours.
`kmixd`	The methodology for modeling the mixed layer depth. There are three options: `0` for using the input (the default), `1` for using temperature, and `2` for using the TKE.
`kmix0`	The minimum mixing depth in meters. This is `250` by default.
`kzmix`	How to perform vertical mixing adjustments. There are three options: `0` for not doing this at all (the default), `1` uses the PBL average, and `3` scales with TVMIX.
`kdef`	The modeling method for horizontal turbulence. We can use the vertical with option `0` (the default), or, use the deformation method with option `1`.
`kbls`	How to derive the boundary layer stability. Two options are available for this. We can use fluxes (option `1`, default) or use wind temperature (option `2`).
`kblt`	The boundary layer turbulence parameterization to use. This can either be Beljaars (option `1`), Kanthar (option `2`, default), or TKE (option `3`).
`conage`	Particle to- or from-puff conversion at CONAGE. In units of hours, with a default of `48`.
`numpar`	The number of puffs or particles released per cycle. By default this is set to `2500`.
`qcycle`	An optional cycling of emissions, in units of hours.
`efile`	An absolute path to an optional temporal emissions file.
`tkerd`	The unstable turbulent kinetic energy ratio. This is set to `0.18`.
`tkern`	The stable turbulent kinetic energy ratio. This is set to `0.18`.
`ninit`	How to do particle initialization; with `0` no particle initialization is done, with `1` this is done once, options `2` and `3` are the add and replace methods.
`ndump`	Should the particles be dumped to a file and, if so, how often? Using `0` results in no writing particles to file (the default), and any non-zero value performs this writing once per number of hours specified.
`ncycl`	The PARDUMP output cycle time.
`pinpf`	The particle input file name (default is `"PARINIT"`). This is useful for initialization or boundary conditions.
`poutf`	The particle output file name (default is `"PARDUMP"`).
`mgmin`	The minimum meteorological subgrid size. The default value is `10`.
`kmsl`	The starting height reference. If it is to signify a distance above ground level (AGL) then use option `0` (the default). If it is instead relative to mean sea level, then option `1` should be used.
`maxpar`	The maximum number of particles to be carried in simulation. By default this is `10000`.
`cpack`	The binary concentration packing. Here are the options: `0` for none, `1` for nonzero, `2` for points, and `3` for polar. Option `1` is the default option.
`cmass`	Informs grid computation. The two options are to compute grid concentrations (with `0`, the default) or to compute grid mass (option `1`).
`dxf, dyf`	The horizontal x- and y-grid adjustment factors for an ensemble. By default, these are both set to `1.0`.
`dzf`	The vertical factor for an ensemble. This is `0.01` by default.
`ichem`	The chemistry conversion module to employ. Option `0` does no chemistry (the default). With option `1` we use a matrix method, option `2` does conversion, and option `3` works on dust.
`maxdim`	The maximum number of pollutants to carry on one particle. By default, this is `1`.
`kspl`	The standard splitting interval in units of hours. By default, this is `1` hour.
`krnd`	The enhanced merge interval in hours. By default this is `6` hours.
`frhs`	The standard horizontal puff rounding fraction for the merge process. This is `1.0` by default.
`frvs`	The vertical puff rounding fraction, which is `0.01` by default.
`frts`	The temporal puff rounding fraction, which is `0.10` by default.
`frhmax`	The maximum value for the horizontal rounding parameter. This is `3.0` by default.
`splitf`	The automatic size adjustment factor for horizontal splitting. By default, the value is `1.0`.
`tm_pres, tm_tpot, tm_tamb, tm_rain, tm_mixd, tm_relh, tm_sphu, tm_mixr, tm_dswf, tm_terr`	Options to include meteorology along trajectory points. These are the pressure variable marker flag (`tm_pres`), the potential temperature (`tm_tpot`), the ambient temperature (`tm_tamb`), the rainfall rate (`tm_rain`), the mixed layer depth (`tm_mixd`), the relative humidity (`tm_relh`), the specific humidity (`tm_sphu`), the mixing rate (`tm_mixr`), the downward short-wave flux (`tm_dswf`), and the terrain height (`tm_terr`). Setting any of these to `0` disables output, whereas `1` will enable output of these data points. By default, all are set to `0`.
