1# CODE TABLE 5 Time Range Indicator 20 0 Forecast product valid at reference time + P1 (P1>0) 31 1 Initialized analysis product for reference time (P1=0). 42 2 Product with a valid time ranging between reference time + P1 and reference time + P2 53 3 Average (reference time + P1 to reference time + P2) 64 4 Accumulation (reference time + P1 to reference time + P2) product considered valid at reference time + P2 75 5 Difference (reference time + P2 minus reference time + P1) product considered valid at reference time + P2 86 6 Average (reference time - P1 to reference time - P2) 97 7 Average (reference time - P1 to reference time + P2) 1010 10 P1 occupies octets 19 and 20; product valid at reference time + P1 1151 51 Climatological Mean Value: 12113 113 Average of N forecasts (or initialized analyses); each product has forecast period of P1 (P1=0 for initialized analyses); products have reference times at intervals of P2, beginning at the given reference time. 13114 114 Accumulation of N forecasts (or initialized analyses); each product has forecast period of P1 (P1=0 for initialized analyses); products have reference times at intervals of P2, beginning at the given reference time. 14115 115 Average of N forecasts, all with the same reference time; the first has a forecast period of P1, the remaining forecasts follow at intervals of P2. 15116 116 Accumulation of N forecasts, all with the same reference time; the first has a forecast period of P1, the remaining follow at intervals of P2. 16117 117 Average of N forecasts, the first has a period of P1, the subsequent ones have forecast periods reduced from the previous one by an interval of P2; the reference time for the first is given in octets 13- 17, the subsequent ones have reference times increased from the previous one by an interval of P2. Thus all the forecasts have the same valid time, given by the initial reference time + P1. 17118 118 Temporal variance, or covariance, of N initialized analyses; each product has forecast period P1=0; products have reference times at intervals of P2, beginning at the given reference time. 18119 119 Standard deviation of N forecasts, all with the same reference time with respect to the time average of forecasts; the first forecast has a forecast period of P1, the remaining forecasts follow at intervals of P2 19123 123 Average of N uninitialized analyses, starting at the reference time, at intervals of P2. 20124 124 Accumulation of N uninitialized analyses, starting at the reference time, at intervals of P2. 21125 125 Standard deviation of N forecasts, all with the same reference time with respect to time average of the time tendency of forecasts; the first forecast has a forecast period of P1, the remaining forecasts follow at intervals of P2 22
