Get Started with JASMIN
Get Started with JASMIN
This article explains the steps involved for most users to gain access to the JASMIN environment.
The JASMIN scientific data analysis environment is administered by CEDA and supports a wide variety of scientific workflows across environmental science domains.
The steps listed in Table 1 (below) are required for scientific end-users to gain ssh access to the JASMIN login machines which are the “front door” for most users. Other services are available once these basic steps have been completed.
An overview of JASMIN compute & storage components is given in the presentation given at the JASMIN workshop - we strongly encourage all new users to watch this video recording and take a look at the accompanying exercises. These go into detail about all the basic things you may want to do with JASMIN.

Step | Details | Comments |
---|---|---|
1 | Generate an SSH key | Create this locally, ready to upload it to your JASMIN Account profile |
2 | Get a JASMIN portal account | Access to JASMIN services is controlled by the JASMIN Accounts Portal - you must register for an account. Using this portal, you will then need to apply for access to the JASMIN services and privileges you require (as described in the steps below). Some of these services will require manual approval by individuals external to the CEDA/JASMIN team. Creating a JASMIN portal account does not by itself provide you with any access to JASMIN machines or services. You must complete all the steps below to gain full access. |
3 | Check network details | Check details of your network connection to JASMIN to ensure you are able to connect. In order to maintain a secure and reliable scientific infrastructure for its users, JASMIN restricts login access by maintaining an “allow list” of network domains. |
4 | Request ssh login access to JASMIN | Apply for the jasmin-login service, which will allow you to connect to JASMIN machines using ssh. |
5 | Apply for access to additional services on JASMIN | JASMIN has a range of additional services, access to which is managed via the Accounts Portal. Search and apply for any services you require in the portal. In most cases, users will “belong” to a particular scientific project which may already have a presence on JASMIN, often in the form of a Group Workspace. See here how to Apply for access to a Group Workspace. |
6 | How to login | Follow these steps for logging in to JASMIN via ssh, but we also have several other tutorials that may be useful - see Exercises 1-3 here. |
7 | Get a CEDA account | The CEDA Archive provides access to thousands of atmospheric, climate change, and earth observation datasets. The Archive is directly accessible read-only throughout JASMIN. Some datasets on the CEDA Archive require specific agreements, and to apply for access to these, you will need a CEDA account. |
8 | Link your JASMIN and CEDA accounts | The final step is to link your CEDA account to your JASMIN account. This allows you filesystem access to data on CEDA Archive. This is a step that you will be guided through in the JASMIN accounts portal. |
The table above describes the initial steps to get you started on JASMIN - however, there are a variety of ways that users can get the most out of JASMIN, that are not described in the table. Users are strongly encouraged to read further about JASMIN, and/or to discuss with scientific colleagues to gain an understanding of the resources available.
The documentation in this site is split into sections, based on different areas/services on JASMIN. You can navigate these sections in the menu on the left-hand side of your screen. A short description of each of these sections is below:
The CEDA team also regularly hosts training workshops and events. Details about past and future events can be found on the events section of the CEDA website.
