Data for January and December is shown. The header record format is as follows: 1. The header record contains the Port Name, Port Number, Year and Zone Time. The height data record format is as follows: 1. Each record is 77 characters long. 2. The first 60 characters is the height data in millimetres. This consists of 12 hourly heights of 5 characters each. Heights of 4 digits, e.g. 1836 , will always have a leading space. Heights of 5 digits, e.g. 12105 , will not have a leading space. 3. The Hourly Height data consists of 2 records. The first record contains 12 hourly heights starting at midnight and ending at eleven am. The second record starts at midday and ends at eleven pm. This gives 24 hourly heights in total. 4. Character 61 of each record is a space. 5. Characters 62 and 63 of each record contain the day. 6. Character 64 of each record is a space. 7. Characters 65 and 66 of each record contain the month. 8. Character 67 of each record is a space. 9. Characters 68, 69, 70 and 71 of each record contain the year. 10. Character 72 of each record is a space. 11. Characters 73, 74 and 75 of each record contain the julian day. 12. Character 76 of each record is a space. 13. Character 77 of each record is the am or pm code. Code 1 indicates that the height data is for the first 12 hours of the day (0000 to 1100 hours). Code 2 indicates that the height data is for the second 12 hours of the day (1200 to 2300 hours).
