l 1996 APPENDIX A Standard Review Plan Section 2.3.3 RECOMMENDED FORMAT FOR HOURLY METEOROLOGICAL DATA TO BE PLACED ON MAGNETIC TAPE * 1 36 2 37 USE: 9-track tape (7 will be acceptable) Standard Label which would include: Record Length = 160 Block Size (3200 - fixed block size) Density (1600 BPI - 800 will be accepted) DO NOT USE: Magnetic tapes with unformatted or spanned records At the beginning of each tape, use the first five (5) records (which is are the equivalent of ten 38 cards) to give a tape description. Include plant name; location (latitude, longitude); dates of data; information explaining data containing in the "other" fields if they are used; height of measurements; and any additional information pertinent to identification of the tape. Make sure all five records are included, even if some are blank. Format for the first five records will be 160A1. Meteorological data format is (I6, I2, I3, I4, 25F5.1, F5.2, 3F5.1). All data should be given to the tenth of a unit, except solar radiation, which should be given to a hundredth of a unit. This does not necessarily indicate the accuracy of the data (e.g., wind direction is usually given to the nearest degree). All nines in any field indicate a lost record (99999). All sevens in a wind direction field indicate calm (77777). If there are only two levels of data, use the upper and lower levels. If there is only one level of data, use the upper level.
