NASA’s Land Atmosphere Near real-time Capability for EOS (Earth Observing System) (LANCE) provides data and imagery from Terra, Aqua and Aura satellites in less than 3 hours from satellite observation, to meet the needs of the near real-time (NRT) applications community. LANCE is a distributed system that builds on the existing EOSDIS capabilities.
LANCE is managed by ESDIS but steered by a User Working Group (UWG) responsible for providing guidance and recommendations concerning a broad range of topics related to the LANCE system, capabilities, and services.
Figure 1 shows a simplified overview of the dataflow from satellite to users.
