Content:
hould describe how the files were created (type of machine, operating system, and programming language), list the contents of each file, and contain a brief description of the meteorological data. The meteorological data description should include the heights of the wind sensors. The description may also include a discussion of data processing that occurred before the data files were created. Use a standard record format for hourly meteorological data. The standard data format is similar to the format described in Appendix A of Standard Review Plan 2.3.3 (NRC 1987). The only differences are in the first two fields of the data records. The second field has been increased to permit specification of the year using four digits rather than two, and the first field has been reduced from six bytes to four bytes and is now specified as a character string rather than an integer. The format for the remainder of the record is identical to the format in SRP 2.3.3. At the beginning of each file, use the first five records to give a data description. Include plant name, location (latitude, longitude), dates of data, information explaining data contained 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 (A4, I4, I3, I4, 25F5.1, F5.2, 3F5.1). Table 2.7-1 shows the size and content of each field in the meteorological data records in the standard format. In addition, it provides a form for recording supporting information about the meteorological instrumentation. 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
