Offshore Physical Environmental Guidelines
Appendix E - Meteorological Metadata Report Format

Meteorological metadata is collected so that better use can be made of the data Adjustments can be made to account for inhomogeneities in the data record, if changes in the instruments are known.

WMO Publication No. 47 (Pub47), the International List of Selected, Supplementary and Auxiliary Ships, [22] contains details about the names, call signs, layout, and types of instrumentation and methods of observation used on VOS ships. The reader should contact MSC for updates to this information.

The information may be reported in tabular format as given here, and/or in semi-colon delimited ASCII text format with all fields on one line. Previous records for the platform should be included, as well as a separate note indicating the field(s) that have changed, to prompt the update to the metadata report. The information is to be provided in electronic format readable by a simple text editor and suitable for printing. Fields that are not applicable should be left blank (for tabular format) or indicated as missing by consecutive delimiters (for the semi-colon delimited ASCII text format). Significant changes to the parameters should be reported to MSC in as near to real-time as possible, e.g. changes to the anemometer height (e.g. due to different water depth, for a anemometer on the leg of a jack-up, or change in position of the instrument), call sign. Meteorological Metadata Reports should be transmitted to the Meteorological Service of Canada (MSC) via email: National.Climate.Archive.Services@ec.gc.ca.
