The frequency data may be input as normalized frequencies, in which case the total of all frequencies for a particular STAR summary will add up to 1.0, or as the number of occurrences for each combination.  If the total of normalized frequencies is not within 2 percent of 1.0, then the model will generate a non‑fatal warning message.  If the total adds up to 2.0 or more and is a whole number, then the model divides the number of occurrences for each STAR category by the total number to obtain the normalized frequency.

     Without the optional STARDATA keyword (described in Section 3.5.4), it is assumed that the STAR summaries in the input file corresponds to the averaging periods selected on the CO AVERTIME card (see Section 3.2.3.1).  If SEASON averages are selected, then the model will assume that the meteorological data file consists of four seasons in the order of WINTER, SPRING, SUMMER, and FALL.  If an ANNUAL average is to be calculated from an annual STAR summary, then the annual STAR should follow any seasonal STAR summaries to be used.  For example, the following runstream image calculates averages for  each of the four seasons and the annual average from a data file consisting of five STAR summaries (winter, spring, summer, fall, and annual):

CO AVERTIME  SEASON  ANNUAL

38

The following example calculates averages for the four seasons, and then calculates an annual average as a period average for the four seasons combined:

CO AVERTIME  SEASON  PERIOD

39

and the input meteorological file for this example would include only the four seasonal STAR summaries.

201 - 202 - 203 - 204 - 205 - 206 - 207 - 208 - 209 - 210 - 211 - 212 - 213 - 214 - 215 - 216 - 217 - 218 - 219 - 220 - 221 - 222 - 223 - 224 - 225 - 226 - 227 - 228 - 229 - 230 - 231 - 232 - 233 - 234 - 235 - 236 - 237 - 238 - 239 - 240 - 241 - 242 - 243 - 244 - 245 - 246 - 247 - 248 - 249 - 250
