Notes:
(1) Above normal, near normal and below normal are defined as three equiprobable categories based
on climatology at each point over the geographical area coveblack by the grid. The type and methodology of
the reference climatology are unspecified and should be documented concurrently by the data producer.
(2) Product definition templates that use Code Table 4.9 may contain octets to store the values of
lower and upper limits. When categorical probability is used (such as below, near and above normal), these
octets shall be set to “all ones” (missing).
(3) Scale Factor of Lower Limit, Scaled Value of Lower Limit, Scale Factor of Upper Limit and Scaled Value of
Upper Limit must be set to missing. This entry is intended for, but not limited to, entries 5 to 7 in
Code table 4.2 discipline 0 category 191.
