The WDCGG encourages Contributors to submit data files that meet the following 6 items for all measurement categories except for hydrographic sampling observation. The submission data file format consists of a header part and a data part. Details of the submitted data file format are as follows:
1) The data file employs an ASCII format. The WDCGG does NOT receive any files in binary formats including MS-Excel or MS-Word, which could include computer viruses, because of computer security policy.
2) The header part includes the following 7 header items that are necessary to identify the submitted data: CONTRIBUTOR, STATION NAME, PARAMETER, DATA TIME INTERVAL, MEASUREMENT UNIT, MEASUREMENT METHOD, AND STANDARD SCALE.
3) The data part is delimiter (such as a space, comma, or tag)-separated format.
4) The data part should, at least, include the date, time, mole fractions, and data flag. For averaged data, the number of data used to average and the standard deviation are also required. Note that an averaged value and its standard deviation are derived from the just one shorter level of the averages. Namely, a monthly mean is derived from daily means, a daily mean is derived from hourly means, and an hourly mean is derived from minutely means. The explicit specification on the definition and the meaning of flag should be submitted as metadata .
5) Each data column should be defined according to Table 5 and Table 6 in the first line of the data part (i.e., the first line of the data part must be the item names of each data column).
6) DATE is represented in YYYY-MM-DD where YY is year, MM is month, and DD is day. The date for monthly data is represented as the first date of the month.
For example, the date of a monthly datum of February 2005 is represented as 2005-02-01. Please note that DATE is the beginning of a measurement or an average. In the case of irregular measurements (e.g. event sample or flask), the end date of the measurement is also required. The WDCGG requires the Contributors to employ time representation compliant to ISO 8601.
7) TIME is represented in hh:mm where hh is hour and mm is minute. In the case of a stationary platform, TIME should be local time, and the time difference between local time and universal time is indicated in Time zone in metadata. A 24-hour clock is used. The representation of time for a monthly or daily datum is 00:00. Please note that TIME is the beginning of a measurement or an average. In the case of irregular measurements (e.g. event sample or flask), the end time of the measurement is also required.
8) In the case that normal datum is not obtained, the data part should use signs such as “-999”, “NA”, or any other combinations of numbers and characters except a space to denote that a datum is not being reported in the field. The field must NOT be left blank. The format of the header part and the order of the data columns are arbitrary. Coincident ancillary data such as associated meteorological data can be included with the gas mole fractions data in the data part.

The WDCGG employs the following naming scheme.
[Station Code].[Contributor].[Observation Category].[Parameter].[Auxiliary item].[Data type].[Data Version].[Extension]
A file name consists of 10 components, Station Code, Contributor, Observation Category, Parameter, Auxiliary item, Data type, Data version, Update date, and Extension. Each component is delimited with a dot. Below is the example of a file name.
