TeraScan version 4.0 brings you all the functionality of version 3.4.1, with additional capabilities such as ingestion of CODAR HF Radar, NEXRAD Doppler radar, and BUFR format files. Support for new satellites and sensors such as COMS, FY2-D, GOES-15, and NOAA-19 DCS is also now available. New modules such as Pulse allow the user to graphically view the progress of Multi-Threaded Parallel Processing in a nicely laid out GUI. TeraScan® v4.0 runs on Red Hat or CentOS Linux 4.x and 5.x, and is delivered via ftp or DVD. Customers currently on a software support contract can receive the upgrade for no additional cost.
