2. System Overview
GOES-R Access Subsystem (GAS) is a subsystem of the GOES-R Ground Segment system
GAS is responsible for receiving and storing GOES-R data and products in 7-day temporary storage and making them available to authorized users
GAS will be developed and integrated as a part of an enterprise NESDIS Data Processing and Distribution operational capability; i.e., as a part of the NESDIS Environmental Satellite Processing Center (ESPC)
