The McIDAS-X Conventional data Decoder (McIDAS-XCD) enables workstations running McIDAS-X to directly receive and process data from the NCEP/NWSTG and NCEP/NWSTG2 channels of the National Weather Service NOAAPORT broadcast. All of the operational McIDAS-XCD client commands for accessing conventional data have been removed from the McIDAS-XCD package. These commands have been replaced with ADDE (Abstract Data Distribution Environment) commands distributed with McIDAS-X. See the Unidata McIDAS User's Guide for more information.
