NASA provides the capability to deliver Near Real-time JPSS data to users in order to monitor time-sensitive applications such as wildfires, floods, volcanic eruptions, tropical cyclones and extreme weather events.
Abstract
NASA's Land and Atmosphere Near real-time Capability for EOS (LANCE https://earthdata.nasa.gov/lance) serves near real-time (NRT) data to monitor time-sensitive applications such as monitoring wildfires, floods, volcanic eruptions, tropical cyclones and extreme weather events. It currently serves data and imagery from the Visible Infrared Imager Radiometer Suite (VIIRS) and Ozone Mapping and Profiler Suite (OMPS) S-NPP instruments and is in the process of integrating continuity data products from VIIRS and OMPS onboard the Joint Polar Satellite System (JPSS), via the JPSS data Hub, to continue to meet the needs of agencies, scientists and members of the general public.
NASA's Earth Science Division (ESD) sponsored the EOSDIS development of LANCE in 2009 to provide a central point of access to high quality NRT data products and imagery for applications users. LANCE makes data available to the public within 3 hours of satellite observation and imagery within 4-5 hours of satellite observation. Full resolution browse imagery from LANCE are provided through the Global Imagery Browse Services (GIBS) which also fuels NASA's Worldview tool so that users can interactively browse near real-time data. This data supports time-critical applications and allows users to view current natural hazards and events and animate the imagery over time. In November of 2017, the Joint Polar Satellite System (JPSS) project started making NOAA-20 data available to the ESDIS managed Science Data Segment (SDS) through the JPSS Block 2.0 architecture via the JPSS Stored Mission Data Hub (JSH). Through the JPSS JSH to SDS interface, the Level 0 data is made available from the SDS to LANCE nominally in under 2 hours from data observation for further processing providing the NRT applications community access to critical data much sooner. This paper will show the data flows and systems that enable the achievement of the latency. LANCE also provides more than 100 near real-time data products created from data collected by sensors aboard NASA's orbiting Terra, Aqua, Aura, and Suomi National Polar-orbiting Partnership (S-NPP) satellites, and for the purposes of data continuity, also from the Advanced Microwave Scanning Radiometer 2 (AMSR2) aboard JAXA's Global Change Observation Mission - Water (GCOM-W1).- Publication:
