9.15.8 Mass Flux List File (MASSFLX.DAT)
Mass flux results for those species selected in the control file are reported to the list file MASSFLX.DAT
for each boundary that is contained in the boundary file FLUXBDY.DAT. MASSFLX.DAT is a
formatted text file that identifies the CALPUFF version and level, echoes the 3-line title of the CALPUFF
simulation, identifies the output as mass flux (g/s), sets out column headings to label each variable listed,
and then reports the mass fluxes for each hour in the simulation. The boundaries are identified by the
names provided in FLUXBDY.DAT, and for each boundary, the mass flux in and out across the boundary
is reported. The date and time of each output record marks the time at the end of the hour, where
midnight is hour zero of the new day (CALPUFF convention).
An example list file is provided in Table 9-62. The four boundaries are identified using the names
provided in the boundary data file. Note that these boundaries do not surround a source, and enclose
small regions so that the fluxes produced across each boundary are frequently both in and out as the puffs
in this example pass through the enclosed regions.
