For 3D views of the NEXRAD data, you could use things like the ORPG or Unidata's IDV which is built on top of VisAD. Each of these requires the Level II NEXRAD data for 3D rendering, not the Level III products that are sent in NOAAPORT. Unidata will be facilitating the distribution of the Level II data to the university community in conjunction with the NWS' collection of the data using the Unidata LDM. This effort is a follow-on to the current CRAFT project being run out of the University of Oklahoma (that also uses the Unidata LDM for data collection and redistribution). >thanks, >Randy Tom
