Section 3. Report: SPLIT For example, referring to Table 3.3-1, if only those hours during day 189 when the temperature was above 90 and the soil temperature was below 62 is desired, or, during day 189 when the average wind speed was below 21 while the wind direction was between 255 to 265 is desired, the Copy condition would be: 1[189]and4[90..150]and5[0..61.99]or1[189]and6[0..20.99]and7[255..265] Only Output Arrays with hours 1300 and 1500, Table 3.3-1, conform to the above Copy conditions. To use the time synchronize function, time element(s) must be specified in the Start Condition (Section 3.3.1.1). The user specifies a time interval in the Copy condition. For instance, if the original data had 15 minute outputs and you only want hourly outputs, then an interval of 60 minutes must be specified following the element number. This is entered as (assuming hrmn is element number 3) “ 3[60]” . If time synchronization is specified in the Start Condition, SPLIT looks for the interval in a time element in the Copy condition. Only one time interval is specified. This interval is the unit of time to synchronize each file. The interval can be given tolerance limits by following the interval with a comma and the tolerance. For example, if 3 is the hrmn element, and the time interval is 60 minutes +2 minutes, the syntax is 3[60,2]. If the time synchronize function is enabled, and data are missing at one or more of the time intervals specified, then a blank (or the comment entered in the “ Replace bad data with” field) is output to the Output File. 3.3.5 Select The Select line specifies which elements of an Output Array are selected for processing and/or output to the specified Output File. The Select line becomes operable only after the Start Condition and Copy condition are met, and before the Stop Condition is satisfied. If the Select line is left blank, all elements in output arrays meeting the Start Condition and Copy conditions are output to the Output File. Up to 255 characters can be entered on one Select line. If this is a limitation, open the Input Data file twice (use the EDIT | ADD DATA FILE menu) and use the Select line in the second Input File template to define the additional operations. 3-18 PC208W, Version 3.3, Instruction Manual
