Remote users can download data from the mainframe, disconnect communications, and operate independently until additional data are needed. The data are compressed before transmission. The SSEC is the national archive for GOES data in digital form. The archive contains a global collection for 1978 and all U.S. data since then. McIDAS is currently installed on IBM 43XX and 3090 systems as well as a few IBM mainframe clones.
Cost varies based on the type of display chosen.
Workstations can be a part of the mainframe's Local Area Network if within the mainframe's site or can communicate remotely. The remote workstations currently communicate with the mainframe via the Trailblazer Plus modem at a maximum rate of 9,600 bps. The BOM staff has developed software to convert the direct broadcast HRPT data to McIDAS format. There is no charge for the McIDAS software for federal government agencies. Both fees are annual.
