Download Data from CEDA Archives
General Download Services
| Download Tool | Link to service | Suitable for: |
| CEDA OPeNDAP |
http://data.ceda.ac.uk | Used for browsing the archive file system and interactive downloads. It's also a scriptable interface (API) to the archive over http, allowing remote subsetting within IDL, Matlab. Python etc. |
| FTP | ftp.ceda.ac.uk and anon-ftp.ceda.ac.uk | small - medium scale data downloads. The anon-ftp.ceda.ac.uk only contains a small subset of data that can be downloaded anonymously (with no login). |
Metadata Services
| Interface | Link to service | Suitable for: |
| CEDA Catalogue |
http://catalogue.ceda.ac.uk/ |
Browsing information about the datasets in the archive. |
| CSW |
https://csw.ceda.ac.uk/geonetwork/srv/eng/csw |
Programatically interrogating the CEDA Catalogue using Catalogue Service for the Web service API. |
| OAI-PMH |
https://csw.ceda.ac.uk/geonetwork/srv/eng/oaipmh?verb=ListRecords&metadataPrefix=oai_dc |
Programatically interrogating the CEDA Catalogue using OAI-PMH API. This is protocol for metadata harvesting and is suitable for doing federated searches. |
Bulk download options
There are various options to bulk download data. You can see our most up to date suggestions by clicking on the 'bulk download options' button on the download service webpage, https://data.ceda.ac.uk (see image below).
Once you have clicked on the button, it will show you our recommended bulk download options.
Specific data set services
Tools to subset or aggregate data before downloading are available for some data. These are linked to from the catalogue page for that dataset.
Examples of these tools are:
- CEDA WPS service: http://wps-web1.ceda.ac.uk/ui/home
- Earth System Grid Federation (ESGF): https://esgf-index1.ceda.ac.uk/projects/esgf-ceda/
- CEDA Satellite Data Finder (Sentinel and Landsat missions currently): http://geo-search.ceda.ac.uk/
- Flight Finder (airborne data): http://flight-finder.ceda.ac.uk/
Direct file system access to the archive
JASMIN is a globally-unique data analysis facility. It provides storage and compute facilities to enable data-intensive environmental science. You can access the CEDA Archive via JASMIN - this allows direct file system access. You will need to create a JASMIN account (if you do not already have one). JASMIN users should consult the JASMIN documentation for more information about direct CEDA Archive access and appropriate data transfer mechanisms.
