LAADS DAAAC Data Migrates to the Cloud

The NASA Goddard Level-1 and Atmosphere Archive Distribution System (LAADS) Distributed Active Archive Center (DAAC) completed the first phase of migrating data to the commercial cloud enterprise starting with the Amazon Web Services (AWS) platform. The migration is part of the NASA Earthdata Cloud program, which aims to "give data users new ways to access NASA's collection of Earth science datasets, improve the efficiency of data systems operations, increase user autonomy, maximize flexibility, and offer shared services and controls." The migration of data to the Earthdata Cloud is a key component of the Transform to Open Science Program (TOPS) as part of NASA's Open-Source Science Initiative.

In early 2023, LAADS DAAC Phase 1 datasets completed migration to the cloud. These datasets include Moderate Imaging Spectroradiometer (MODIS) Geolocation, Cloud Mask, and Level-2 and Level-3 Atmosphere Products, as well as the LAADS DAAC products from NASA's Earth Science Data Information System's (ESDIS) list of most popular 75 products.

The second phase will include the Visible Infrared Imaging Radiometer Suite (VIIRS) Level-1, Geolocation, and Atmosphere products. Migration of these datasets is anticipated to complete in 2023, followed by MODIS Level-2 Surface Reflectance products, Long Term Data Records derived from Advanced Very High Resolution Radiometer (AVHRR) on National Oceanic and Atmospheric Administration's (NOAA) Polar Operational Environmental Satellites (POES) and the European Space Agency's (ESA) Meteorological Operational satellite (MetOps), Medium Resolution Imaging Spectrometer (MERIS), Sentinel 3A and 3B Level-1 products, and Airborne products. A full list with updated information is available on the LAADS DAAC Cloud webpage.

LAADS DAAC primarily archives and distributes data on clouds, water vapor, and aerosols in Earth's atmosphere as well as key instrument data from NASA, NOAA and ESA missions. LAADS DAAC also serves as a backup source for MODIS and VIIRS land products. All LAADS DAAC datasets are anticipated to be available via the NASA Earthdata Cloud by the end of 2024, but will continue to be available to users using a hybrid on-premise/cloud strategy throughout the transition period.
