[Datastream #RPP-204292]: Question about NEXRAD national composite data

Great, we have done much work with U of Iowa, including the HYDRO-NEXRAD project

Yes, we are not an archive center, we deliver real time data, and provide a 
short archive for ease of access.

We do not have an archive of the older data, however, IIHR at U of Iowa has had 
a long time feed and I believe they have kept an archive of the individual 
radars
not the mosaic. Do you have a contact at the IIHR on the U of Iowa campus? If 
not, you should contact Anton Krueger, he can inform on the data they have.

No

Also, as part of the Big Data Project, ALL level II RADAR data from 
1992-present is available in the AWS cloud. So, one could create an instance in 
the same zone as the collection
and then re-create the mosaics..or grab the radars of interest for the time 
desired.

The TDS (THREDDS Data Server) sitting on top of the collection can be found at:

and more info about the project and data access can be found at:
