NASA's Atmospheric Science Data Center's Approach to a Cloud-Based Model of Ingest, Archival, and Distribution of TEMPO Data: Methods, Challenges, and Best Practices

The National Aeronautics and Space Administration's (NASA) Atmospheric Science Data Center (ASDC)at NASA Langley Research Center in Hampton, VAprovides atmospheric science data products and services to the science community, including enhanced search andsubsettingcapabilities for numerous datasets. TheASDCis theofficialDistributed Active Archive Center (DAAC) of recordfor the upcoming Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument. TEMPO will be situated on a geostationary satellitepositioned at a longitude near the center of the conterminous United States and focused onNorth America, making hourly swaths of its field of regard from east to west.ASDC'sdata products arecurrentlyhosted locally and services (e.g.,spatialand temporalsubsetting) aremanagedon premises.TheASDCisplanning to provideTEMPO data and services in the cloud through theEarthdataSearch platform. This presentation will discuss theASDC'sapproach to a cloud-based model of ingest,archival, anddistribution of TEMPO data. Methods, challenges, best practices, lessons learned, and future plans will be discussed.
