Depositing Data at CEDA: A step by step guide
CEDA will accept data relevant to atmospheric and earth observation fields. This includes a wide range of instrumental, satellite, aircraft, observations, analyses and model datasets of interest to the scientific community. To archive data with CEDA please follow the steps below (please also see the FAQ's and webinar).
Step by step guide
Once you have collected/produced your atmospheric or earth observation data; processed, calibrated, validated and quality checked it and prepared it for archiving using correctly applied standard data formats (for example, NetCDF should adhere to the CF conventions and have good quality metadata including global attributes) and meaningful filenames, you are now ready to upload it to the CEDA archive, using the following steps.
1. Register for a CEDA account.
2. Go to arrivals.ceda.ac.uk and login with your CEDA username and password.
3. Click begin. You need to agree to the deposit agreement the first time you use the service.
4. Click browse deliveries.
5. Choose an existing delivery directory or create a new delivery directory by clicking on 'new directory'. (Add a suitable title e.g. the project, instrument name, model name or what the data contains, etc).
6. Upload your files using the following tools if appropriate. Fix bad names (this removes unusual characters and spacing), remove empty directories and remove zero length files.
You can also upload your data via FTP or RSYNC (more information can be found on the 'other upload method' button). If you use these methods you still need to come back to the web interface to submit the data.
7. Create and upload a metadata.yaml text file along with the data. The metadata.yaml file needs to contain the details of the dataset, project and instrument or model. Adding the information this way helps keep the record and the data together. To create the metadata file use this utility or edit one of the examples below.
8. Click check delivery button.
9. Confirm Submission.
10. A CEDA contact will check the files and move them to the CEDA archive. Catalogue records will be created to make your data discoverable (using the metadata you supplied in step 7). This takes time, so please be patient with us.
11. Finally, we will ask you to review these catalogue records, and when all checks are complete your dataset will be published.
12. If you requested a DOI for your dataset, it can then be provided.
