Hi Maria,

Another way I can assist is by offering a remote IDV training class for your 
students. We can spend one hour or so covering
 some basic features of the IDV, or delve into more advanced features for 
analyzing certain datasets. 

For the climate study, I can assist your student in learning how to access 
remote data server from NASA and NOAA.

Anyway, there are many things we can do together in the future.

Best,

Yuan
