( 1) Hours greater than 65534 will be coded as 65534.
( 2) The reference time in section 1 and the forecast time together define the beginning of the overall time interval.
( 3) An increment of zero means that the statistical processing is the result of a continuous (or near continuous) process, not the processing of a number of discrete samples. Examples of such continuous processes are the temperatures measured by analogue maximum and minimum thermometers or thermographs, and the rainfall measured by rain gauge.
