     The parameter Qflag is the variable emission rate flag, and is one of the following secondary keywords: 

SEASON ‑ emission rates vary seasonally (n=4),

MONTH  ‑ emission rates vary monthly (n=12),

HROFDY ‑ emission rates vary by hour‑of‑day (n=24),

STAR   ‑ emission rates vary by speed and stability

         category (n=36), and

SEASHR ‑ emission rates vary by season and hour‑of‑day

         (n=96)

The Qfact array is the array of factors, where the number of factors is shown above for each Qflag option.  The EMISFACT card may be repeated as many times as necessary to input all of the factors, and repeat values may be used for the numerical inputs.  An example of each of these options is presented below, with column headers to indicate the order in which values are to be input.
