 Conditions for access to the AeroCom data server:
   * A short project description of the planned analysis is send to AeroCom contact (michael.schulz@met.no)
-  * An account is opened upon sending a request for an account to michael.schulz@met.no and jan.griesfeller@met.no
+  * An account is opened upon sending a request for an account to (Michael) michael.schulz@met.no and (Anna) annac@met.no and (Jan) jan.griesfeller@met.no
   * The project description is made available to AeroCom participants via this [[aerocom:data_base_user_overview|wiki page]]
   * Results from analysis are reported to AeroCom workshops
   * Publication-Coauthorship is offered to model and data author. See [[aerocom:data_policy|data policy]]
-At first you will get a username and a password for ftp.aerocom.met.no only. The main purpose for it is to send us data.
+At first you will get a username and a password for this wiki. To get access to the user server __aerocom-users.met.no__, you have to send us a ssh public key since password authentication is disabled for security reasons on the user server. You can connect to the user server via //**ssh**//, but also use //**scp**// and //**rsync**// for data transfers.
-In order to get access to the user server aerocom-users.met.no as well, you have to send us a ssh public key since password authentication is disabled for security reasons on the user server.
+For more details on AeroCom database, please read about [[https://wiki.met.no/aerocom/data_submission|data submission procedure]].

 === Step 2: Generate a new SSH key ===
-=== Step 3: Send your key to jan.griesfeller@met.no ===
+To generate a new SSH key, enter the code below. We want the default settings so when asked to enter a file in which to save the key,
+just press enter.
+<code> $ ssh-keygen -t rsa -C "my comment"
+Generating public/private rsa key pair.
+...
+</code>
+Enter the path to the file that will hold the key: By default, the file name $HOME/.ssh/id_rsa, which represents an RSA v2 key,
+appears in parentheses.
+<code> Enter file in which to save the key (/home/user/.ssh/id_rsa): <return> </code>
+Enter a passphrase for using your key: The passphrase you enter will be used for encrypting your private key. A good passphrase should be alphanumeric having 10-30 character length. You can also use a null passphrase however this can cause a security loophole.
+<code>Enter passphrase (empty for no passphrase): <Type the passphrase> </code>
+Re-enter the passphrase to confirm it: Type your passphrase once again to confirm it.
+<code>
+Enter same passphrase again: <Type the passphrase>
+Your identification has been saved in /home/user/.ssh/id_rsa.
+Your public key has been saved in /home/user/.ssh/id_rsa.pub.
+The key fingerprint is:
+b:fa:3c:b8:73:71:bf:58:57:eb:2a:2b:8c:2f:4e:37 user@myLocalHost
+</code>
+=== Step 3: Send your public key to jan.griesfeller@met.no and anna.benedictow@met.no ===
+In the folder ~/.ssh you will find file(s) ending with .pub. Please send us the one you just created e.g. <key> id_rsa.pub</key>. **And no other file**
