WRFDA Practical Sessions

IMPORTANT NOTE: After you have logged on and opened a terminal window, change directory to the main working directory for WRFDA tutorial practice:

cd /data1/${USER}/DA

 

Refer to WRFDA User's Guide if you need more detailed descriptions on various components of the WRF Data Assimilation System.

Tutorial presentations can be accessed through the links on each session's page.

For basic practical sessions, step-by-step instruction is provided to help you get a clear idea of what input files are required, what namelist variables need to be set, and what executable is used. Once you have this important basic knowledge, you should be able to build your own scripting system for your applications and environment.

For advanced practices, only a general description is provided. You are encouraged to refer to the tutorial presentations, user's guide and READMEs to figure out how to accomplish the task.
