Using the CEDA Data Catalogue

The CEDA data catalogue has been designed to allow users to quickly find relevant data and related background information and related data of interest. This introduction gives some basic information about how it is structured and therefore how best to find data you wish to use.

Key Concepts

Underpinning CEDA's data catalogue are some key concepts that are useful to understand. The catalogue is centred on the following key types of record:

  • Dataset - these records describe and link to the actual data in our archive. They also provide spatial and temporal information, access and usage information and link to background information on why and how the data were collected.
  • Dataset Collection - a collection of Datasets that share some common purpose, theme or association. These collections link to one or more Dataset records.
  • Project - background information about a project, programme or other major activity that provides the purpose for producing the data. Navigate from this record to the related Dataset record(s) (via the relevant Dataset Collection) to access the data.
  • Instrument - describes an instrument that is used to collect data via observations. Follow the link to the associated Dataset records to access the relevant data.
  • Platform- describes a platform (e.g. sites, stations, aircraft) on which instruments were mounted/located during the data collected during a project. Follow the link to the associated Dataset records to access the relevant data.
  • Computation - describes computational stages in producing data - e.g. models, processing algorithms, used to produce data such as NWP and climate model output and Earth Observation higher level processed products. Follow the link to the associated Dataset records to access the relevant data.

What happens when I search?

Using the CEDA Catalogue search in its default setting will try and match your search term across a range of information fields (e.g. title, abstract, keywords) in all the main records in the catalogue.

A summary of records ranked in order of relevance will then be displayed with links to further information, to download data, apply for access or related datasets where relevant for the different record types.

These records can easily be filtered by the different record types at the top and sorted by alphabetical ordering or relevance (i.e. highest match scores at the top of the list) to further help you explore the results.

Browsing from one record to another

The various record types held in the catalogue are connected ways that you would expect. For example, a Dataset Collection may consist of many Datasets and they can both be related to a particular Project. Once you are viewing a particular record a set of related records will be shown on the right hand side of the screen so you can browse the linkages between different records in a logical manner.

View records with DOIs

CEDA has the authority to assign Digital Object Identifiers (DOIs) to datasets. See DOI-assigned Collections and Datasets
