Starting the Volcanic Ash Retrieval Program

This program is constantly changing, so consult the system administrater for more information if these commands do not work. These instructions are for users in the Laboratory of Atmospheric Remote Sensing at MTU.
  1. Shell to tephra....wait for the new tephra window to appear.
  2. In the tephra window, type var1 for VAR v1.0B and var2 for VAR v2.0B. At some point, var1 will be removed and only the current version will be accessible.
  3. Typing the above command will start IDL, at the prompt type var to start the program.
  4. That's all there is to do!
