FDS outputs 3D smoke quantities as 8 bit integers compressed using run length encoding. Soot density, HRRPUV or temperatures are first scaled to 8 bit integers (soot density is converted to an opacity first). Repeated integers are replaced by $n$I where $n$ is the number of repeats and I is the value repeated.

You can change the scale of \ct{HRRPUV} via the parameter \ct{HRRPUV_MAX_SMV} (default 1200~kW/m$^3$) on the \ct{DUMP} line. You can change the \ct{TEMPERATURE} bounds via \ct{TEMP_MIN_SMV} and \ct{TEMP_MAX_SMV} (default 20~$^\circ$C and 2000~$^\circ$C).
