This page contains links to tutorials we have developed for working with NERC-ARF data. Most of these tutorials were created as part of the NERC-ARF Workshop, which is held annually. If you are interested in attending a future workshop please contact us.

== Data ==

Data for all the tutorials can be downloaded as a [https://nerc-arf-dan.pml.ac.uk/files/tutorials/nerc-arf-tutorials_data.zip 3.2 GB zip file]. If you wish to download data from other areas you can browse the NERC-ARF archive at [http://data.ceda.ac.uk/neodc/arsf/ CEDA (login required)].
