- creationDate:Date and time (using ISO8601 format) that the data product was produced. This is a valuable indicator for comparing to other revisions of the same data product.
- deviceDetails: a structure array with a structure for each deployment, with the following fields:
- deviceDeploymentDateFrom
- deviceDeploymentDateTo
- deviceID: A unique identifier to represent the instrument within the ONC observatory.
- deviceName: A name given to the instrument.
- deviceCategory: A unique name given to the category of devices, such as 'CTD'
- deviceCode: A unique string for the instrument which is used to generate instrument search data product file names.
- location: a structure array with a structure for each deployment location, with the following fields:
- locationName: The node of the ONC observatory. Each location contains many sites.
- stationName: Secondary location name.
- depth_metres: Obtained at time of deployment. If NaN, the device is mobile and this position is a variable, the data for which is supplied by a sensor in the data struct.
- lat_degrees: Obtained at time of deployment. If NaN, the device is mobile and this position is a variable, the data for which is supplied by a sensor in the data struct.
- lon_degrees: Obtained at time of deployment. If NaN, the device is mobile and this position is a variable, the data for which is supplied by a sensor in the data struct.
- heading_degrees: Obtained at time of deployment. If NaN, the device is mobile and this position is a variable, the data for which is supplied by a sensor in the data struct.
- pitch_degrees: Obtained at time of deployment. If NaN, the device is mobile and this position is a variable, the data for which is supplied by a sensor in the data struct.
- roll_degrees: Obtained at time of deployment. If NaN, the device is mobile and this position is a variable, the data for which is supplied by a sensor in the data struct.
- dataQualityComments: In some cases, there are particular quality-related issues that are mentioned here. This is distinct from QAQC information contained in the data structure.
- totalScalarSamplesReceived: A count of the total number of all scalar data samples received. The number of time stamps that have any valid data on any sensor (at each time stamp). Only defined for metaData(1).totalScalarSamplesReceived, as this total is a summary of all device deployments in the data product.
