If the CETI value is calculated to be 35 C or greater and night cooling is present then the
temperature adjustment is set at .783. If CETI is 35 C or greater and night cooling is not present
the temperature adjustment is set at .65. The lower temperature at which CETI becomes constant
is –15 C. At this temperature and below, the temperature adjustment factor is set at 1.16. The
calculated adjustment factor is multiplied by the fecal output factor calculated thus far in the
model. The values suggest by NRC 1996 Errata and the values produced by using the equation
above are graphed in Figure 7 to show the relationship established.
