JASMIN access may be provided for all projects within the NERC remit * and either working at or collaborating with an eligible UK institution (n.b. the actual person may or may not be based in the UK; short-term training accounts may be requested by event organisers (not by attendees) for particular events).

The best way to start with JASMIN  is to go through the Getting started with JASMIN webinars you can find on https://www.ceda.ac.uk/events/getting-started-with-jasmin-webinar/ and the first few sections of https://help.jasmin.ac.uk/category/158-getting-started. (the webpage at https://jules-lsm.github.io/tutorial/bg_info/tutorial_julesrose/jr_jasmin_setup.html also has similar notes, though much briefer). Access JASMIN as follows:

1. You must be able to use an affiliated email (i.e. a student or staff institutional email provided by an academic or private institution, not a personal gmail or hotmail address).
2. JASMIN will only allow access from affiliated servers / registered IP addresses and will automatically refuse access from unrecognised machines (e.g. personal laptops), even if you have applied correctly for a login below. Therefore, the first thing to assess is whether you are able to log in to JASMIN at all. If you can access any sort of server (whether at an academic institution or not), as long as it has a reverse DNS entry then you should be OK. You may need a VPN to be able to access that server as well. Test this by doing the "Check IP address resolves ..." test on here. Best is to contact your IT support or IT manager at your affiliated institution (whether academic or private) to assess the situation on these points. Please check that you have access to the other basic requirements listed here for JULES access.
   
3. All JASMIN users need to have a CEDA login, a login account and an SSH key. These videos describe the process in detail (see also Get started with JASMIN). On approval, you will automatically be subscribed to the JASMIN-USERS Jiscmail listserv, and note the CEDA support email is support at ceda dot ac dot uk (see also CEDA Help).
   
4. Optionally, it might make your life a little easier to add some useful aliases to your .bashrc files. This is NOT ESSENTIAL, but see here for details.
   
5. JASMIN users wishing to use the JULES land surface model long-term should also request access to some relevant services (although n.b. You will NOT need access to any services for any of my trainings courses or the Hydro-JULES Summer School). JASMIN services you are subscribed to are listed here and clicking on “Group workspaces” or “Additional services” on the left show you other services that are available (see also JASMIN Help). NERC-funded users can request access to nerctools (NERC software tools) and jules (JULES workspace), but n.b. these are NOT necessary for the Summer/Winter Schools. Check whether you have access to e.g. the jules workspace with this command: ls -ltr /gws/nopw/j04/jules.
   
6. Make sure you are familiar with the other tools available through CEDA and JASMIN - they can make your life much easier! - including the CEDA Data Catalogue, the JASMIN Analysis Platform and other JASPY software environments.
   
7. Finally, be aware that CEDA runs regular webinars that can be very useful in learning how to use all these and other tools.
   

* Working "within the NERC remit" essentially just means you are in the broad area of Environmental Science. For more specific information see here.
