Commonly asked questions:

What can I do here?

As a data provider (i.e. SLR station operator), you can upload your data on this platform.

How do I register?

To open an account, simply use the 'Sign Up' function in the top right corner. You will be able to select a username and set a password. After your first login, please wait until we have manually connected your account to an institution / company. Only after this linking, will you be able to use the features of the system.

Should I share my account with other people in my department?

No, each person can have their own personal account. We will manually connect all accounts from the same company / institution / department together, so they can see and access the same data and functionalities.

How will you use my E-Mail address?

We can send you E-Mails e.g. with the schedule of your observations, or a notification if new data has arrived. You can turn these E-Mail notifications on and off in your user settings. Apart from that, it is only used for the password reset functionality.
