3.1. Naming conventions

All products are in NetCDF4 Classic format. They comply to the CCI Data Standard 2.2 and follow the CF 1.12 and ACDD 1.4 conventions.

The file nomenclature is based on form 2 of CCI recommendations :

ESACCI-<CCI Project>-<Processing Level>-<Data Type>-<Product String>[-<Additional Segregator>]-<IndicativeDate>[<Indicative Time>]-fv<File version>.nc

Where:

• <CCI Project> : SEASTATE

• <Processing Level> : here L2P for along-track data, L3 for edited merged product and L4 for monthly averages

• <Data Type> : SWH for “Significant Wave Height”, ISSP for “Integrated Sea State Parameters”

• <Product String> : contains the name of the mission for L2P

• <Additional Segregator> : optionally the name of algorithm used

• <Indicative Date>[<Indicative Time>] : The identifying date for this data set. Format is YYYYMMDDTHHMMSS, where YYYY is the four digit year, MM is the two digit month from 01 to 12 and DD is the two digit day of the month from 01 to 31. The date used should best represent the observation date for the data set. For along-track data it will be the time of the first measurement in the file.

• <File version> : File version number in the form n{1,}[.n{1,}] (That is 1 or more digits followed by optional . and another 1 or more digits.)
