CEDA Data Viewing options:

The following links are useful for working with CEDA - the centre for envrionmental data analysis data archive.

1. Identifying suitable data

1. CEDA Satellite Data Finder: Allows you to show tiles of satellite data and filter by time, area, satellite, etc.
2. CEDA Catalogue search: Allows you to search via keywords

2. Accessing data

On Jasmin, some CEDA data is stored on disk, while other data is stored on tape. They are accessed differently, as explained below.

2.1 To get access to disk data:

Simply log in to Jasmin and navigate to /neodc, which is where most of the CEDA data lies on Jasmin. For example, you can find the ESA CCI land cover data in /neodc/esacci/land_cover/data/land_cover_maps/v2.0.7.

2.2 To get access to tape data:

• Go to the near-line archive site of ceda, click on help and email them asking for a tape quota. You'll typically get approved for a 2TB tape quota in a few hours.
• From your home directory, activate your conda/jaspy environment then do git clone https://github.com/cedadev/nla_client and pip install ./nla_client
• Follow the instructions in the link above to request files - you can set it to notify you by email when your files are delivered to JASMIN CEDA. I found it easiest to make a pattern request, so something like pattern_request S2A_MSIL1C_20190225T090941_N0207_R050_T35UPR works for a specific file.
