Hi All- The THREDDS Data Server (TDS) at UCAR that serves up grids and radar images (through TDS Radar Chooser) has been updated to a new version (4.0). This new server has several bug fixes and seems to serve up data faster than the old one. Every effort has been made to maintain backward compatibility with IDV bundles that point to the TDS on motherlode. The NSF server will be updated soon to be consistent with the UCAR server. Please let us know if you encounter any problems with the new server by sending a message to support-idv@xxxxxxxxxxxxxxxxx Thanks. The IDV and THREDDS teams.
