188.8.131.52 Long Term Model Options.
The EMISFACT keyword provides the user the option of specifying variable emission rate factors for sources modeled by the Long Term model. The syntax, type and order of this keyword are summarized below:
SO EMISFACT Srcid (or Srcrng) Qflag Qfact(i),i=1,n
Must follow the LOCATION card for each source input
where the Srcid parameter is the same source ID that was entered on the LOCATION card for a particular source. The user also has the option of specifying a range of sources for which the emission rate factors apply, instead of identifying a single source. This is accomplished by two source ID character strings separated by a dash, e.g., STACK1‑STACK10. The use of the Srcrng parameter is explained in more detail in Section 3.3.3 above for the BUILDHGT keyword.
The parameter Qflag is the variable emission rate flag, and is one of the following secondary keywords:
SEASON ‑ emission rates vary seasonally (n=4),
QUARTR ‑ emission rates vary by quarter (n=4),
MONTH ‑ emission rates vary monthly (n=12),
SSTAB ‑ emission rates vary by season and stability
SSPEED ‑ emission rates vary by season and speed (n=24),
STAR ‑ emission rates vary by speed and stability
SSTAR ‑ emission rates vary by season, speed and
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.
151 - 152 - 153 - 154 - 155 - 156 - 157 - 158 - 159 - 160 - 161 - 162 - 163 - 164 - 165 - 166 - 167 - 168 - 169 - 170 - 171 - 172 - 173 - 174 - 175 - 176 - 177 - 178 - 179 - 180 - 181 - 182 - 183 - 184 - 185 - 186 - 187 - 188 - 189 - 190 - 191 - 192 - 193 - 194 - 195 - 196 - 197 - 198 - 199 - 200
