| Notes: (1) The input process identifier shall have the value of the "analysis or forecast process identifier" of the original GRIB message used as input of the post-processing. (2) The input originating centre shall have the value of the "originating centre" of the original GRIB message used as input of the post-processing. (3) This identifies which post-processing technique was used. This is defined by the originating centre. (4) Hours greater than 65534 will be coded as 65534. (5) The reference time in section 1 and the forecast time together define the beginning of the overall time interval. |
