How do I use the specific UI like these sites?

["cch" <cch@xxxxxxxxxx>]



Dear all,

 

Can I change my UI to other style like these sites?

http://data1.gfdl.noaa.gov/las4/main.html

Actually, I have two questions:

(1) Does there has existed template to use? Or I shuld modify velocity myself ?

(2) Why there are no "Define variable" item on these UI style sites??

 

Thanks very much!!
