If you want access to MARS, see the MARS instructions.
If you want access to the SMHI HSM storage, see the SMHI HSM storage instructions.
If you want access to a dedicated SMHI cluster such as Bi or Frost:
Talk to your user group representative. For Bi, it is Michael Kolax for the Rossby Centre and Anders Höglund for all other user groups. For Frost it is Lars Berggren. He needs to know your email address, direct phone number and the department you are going to use the cluster on behalf of.
The user group representative will communicate with NSC. We will then create your account and you will receive an email to your email address with your username and preliminary password. Login using SSH as soon as possible (within seven days) to set a new, unique and good password.
If you want to run on one of the general academic systems, you need to follow the normal procedures for applying for new projects, becoming a member of a project and getting a login account. It is the SMHI resources that are handled specially, not the users from SMHI.
