Metadata

Metadata reports are now available with many different data products, including the scalar data products. These PDF reports are produced automatically when a data search is completed and are made available via a link adjacent to the data, see step 3 in data search help. The reports contain extensive information about the data, including instrument location, deployment, calibration, data quality and data gaps.

Conventions

Timestamps: Timestamps are always in UTC and follow the ISO8601 convention: yyyymmddTHHMMSS.FFFZ. In some cases, the millisecond portion is omitted.

Filenames: Note that the underscore character, "_", is used to separate the components of the names. It is also used to replace any spaces in the name to maintain compatibility.

For an instrument type search, files are named as DEVICECODE_SENSORCODE_yyyymmddTHHMMSSZ-MODE.EXT where:

• DEVICECODE is a string unique to each instrument. May have (DEVICEID) appended to DEVICECODE.
• SENSORCODE is a string unique to each sensor, and is only included if a single-sensor data product was requested.
• yyyymmddTHHMMSSZ is the timestamp (ISO8601 format) which represents the initial time for data in the file. May have millisecond information: yyyymmddTHHMMSS.FFFZ, where 'FFF' are the milliseconds.
• MODE is optional text which allows files to be differentiated, as necessary, when they refer to the same device and share the same extension. For instance, the VPS cast products supply the end date here.
• EXT is the file extension.

For location search, files are named as STATIONNAME_DEVICECATEGORY_SENSORNAME_yyyymmddTHHMMSSZ-MODE.EXT where

• STATIONNAME is the station name, including site tree nodes separated by dashes, for example: BarkleyCanyon-VPSUpperSlope.
• DEVICECATEGORY is the device category, such as 'CTD'. If there is more than one device in the category, the file will contain multiple devices.
• SENSORNAME is the sensor name and is omitted for a device-level data product that contains multiple sensors.
• yyyymmddTHHMMSSZ is the timestamp (ISO8601 format) which represents the initial time for data in the file. May have millisecond information: yyyymmddTHHMMSS.FFFZ, where 'FFF' are the milliseconds.
• MODE is optional text which allows files to be differentiated, as necessary, when they refer to the same device and share the same extension. For instance, the VPS cast products supply the end date here.
• EXT is the file extension.
