The metadata line is deliberately flexible - it's OK to use it for anything, as required. But we should standardise, where possible, on common entries.
| Abbreviation | Value | Description |
|---|---|---|
| orig | =any | Original observation value with units (e.g. '33F', '29.78in') |
| orig.date | =any | Original observation date, when different from the date provided in the Year, Month, Day columns (e.g. '23 September 1902') |
| orig.time | =any | Original observation time (e.g. '14:30LST', 'noon') |
| PTC | =[Y,N,?] | Only for pressure: have the observations been corrected for temperature? |
| PGC | =[Y,N,?] | Only for pressure: have the observations been corrected for gravity? |
| atb | =any | Only for pressure: original temperature of the barometer with units (e.g. '55F') |
| Alias | =any | Alternative station name |
| Data policy | =any | Data licence, see here for some examples (e.g. 'WMO essential') |
| Calendar | =any | To be used if a calendar different from the Gregorian is adopted, in particular for monthly data (e.g. 'Julian') |
Capitalized abbreviations can be used in the header (in that case they apply to all observations provided in the SEF file, unless differently specified in the Meta column).
