Logging In

There are several ways to login to ISIS. The first involves navigating to the login page directly. For example, on the NCDC Web Site, you can access ISIS via this hyperlink: /access/isis/login.htm

Login appears in ISIS header

Another way to login to ISIS is to click on the "login" hyperlink which appears in the header of some ISIS pages when you are not logged in. For example, the station list page can be viewed by anyone without logging in, but it provides a link to the login page.

When you are not already logged in to ISIS, one final way to login is to attempt to access a page which requires authentication. For example, if you attempt to access the home page, you will be redirected to login first.


Logging Out

User name and logout link appear in ISIS header

If you are logged in, your user name will display in the page header. Below your user name there is a link to "Logout". Click on this link, and you will be logged out of ISIS and taken to the Login screen.
