Hi Emily,

I did add a plugin for the WRF Hydro dataset, but still in the process of 
revising the
logic as the Hydro group has not gave me their final version of output format.

As I know, there are many different output formats in the current release, I am 
not 
sure if your dataset is one of the format the IDV can support. So, could be
upload a sample file for me to test, I will email you the plugin if it is 
working in the IDV.

Hi Emily,

Could you upload a sample file for me to test?
