Input Group 13

Subgroup (13d)
---------------
a
POINT SOURCE: VARIABLE EMISSIONS DATA
---------------------------------------
Use this subgroup to describe temporal variations in the emission
rates given in 13b. Factors entered multiply the rates in 13b.
Skip sources here that have constant emissions. For more elaborate
variation in source parameters, use PTEMARB.DAT and NPT2 > 0.
IVARY determines the type of variation, and is source-specific:
(IVARY) Default: 0
0 = Constant
1 = Diurnal cycle (24 scaling factors: hours 1-24)
2 = Monthly cycle (12 scaling factors: months 1-12)
3 = Hour & Season (4 groups of 24 hourly scaling factors,
where first group is DEC-JAN-FEB)
4 = Speed & Stab. (6 groups of 6 scaling factors, where
first group is Stability Class A,
and the speed classes have upper
bounds (m/s) defined in Group 12
5 = Temperature (12 scaling factors, where temperature
classes have upper bounds (C) of:
0, 5, 10, 15, 20, 25, 30, 35, 40,
45, 50, 50+)
1 ! SRCNAM = BLR1 !
1 ! IVARY = 2 ! (12 Months)
1 ! SO2 = 0.1,0.1,0.5,0.9,2,2.2,
2.5,1.5,1.1,0.9,0.5,0.1 !

Data for each species are treated as a separate input subgroup
and therefore must end with an input group terminator.
