NBCX integer Number of segments along north or south boundary of the
computational domain
NBCY
Number of segments along east or west boundary of the
computational domain
IBCU integer Units for boundary concentrations 2
1 = g/m**3
2 = ug/m**3
3 = ppm
4 = ppb
NTYPEBC1 integer Number of air-mass types that are treated as constant, or
that are varied using temporal factors (Group 3)
NTYPEBC2 integer Number of air-mass types that are varied hourly (Group 5) 2
NSPECBC integer Number of species in each air-mass 5
NSBC
integer
(Input Group 2 - Species List)
Number of air-mass type / species combinations with
variable concentration scaling factors provided in (3b)
CSPEC character Species name (NSPECBC records are required). These
*12 names are passed into the data dictionary for later use
when assigning properties for particular species.
XMWTBC real array Molecular weight (g/mole) for each species (used ONLY
(mxspec)
if IBCU=3,4 to convert to mass concentration), assigned
by species dictionary name
