GOES sounder products are available for the lower 48 states every hour, less frequently (1 to 4 hours) for special sectors covering Hawaii, Central America, the Caribbean, and the western Atlantic. Approximately one hour is required to receive, process, and distribute products for one sector. For example, a GOES-West sounder scan started at 22:01 UTC is completed in 20 minutes. After processing and distribution, products from that sector become available at about 23:01 UTC.
