1 g of NO3 contributes 0.452623 g of N
As illustrated in the sample control file, each new species is identified by name using the data dictionary
variable CSPECCMP, and then each species weight is assigned by name. These species names must
match those NSPECINP names already provided in subgroup 2a. The! END! terminates each of the
NSPECCMP groups.
Subgroup 2d is not used in this sample, and could have been deleted from the file. Its structure is similar
to that of subgroup 2c. There must be NSCALED groups provided, and each group is closed with the
!END! terminator. Within each group, the file that is scaled is identified by name, assigned to the data
dictionary variable MODDAT. This name must match one of the file names provided in subgroup 0b.
After the file is identified, the scaling parameters are assigned to each species by name. Again, the
species names must match those NSPECINP names assigned in subgroup 2a.
A sample list file is shown in Table 10-12. The top part of the file repeats the records from the control
file. The remainder of the file restates the major selections, reports any warning messages, lists
information from the header of each CALPUFF data file that is processed, and it reports the full species
names that are read and written.
