The NOAA organization, National Environmental Satellite, Data, and Information Service (NESDIS) controls access to the GOES DCS system and its data. To become a GOES DCS user, you must complete the application process which is outlined here.
Once a user is approved by NESDIS, they will have access to the data feeds coming from the Wallops facility. They will also have access to the data feeds available from the EDDN. The userid used to access the LRGSs at Wallops will be the same for the EDDN LRGSs.
