Abstract text OpenAltimetry [1] is an open data discovery, access and visualization platform for spaceborne laser altimetry data, specifically data from the Ice, Cloud and land Elevation Satellite (ICESat) mission and its successor, ICESat-2. Developed under a 2015 NASA ACCESS grant, its intuitive, easy-to-use interface quickly became a favorite method for browsing and accessing ICESat-2 data among both expert and new users. As the popularity of computational notebooks became grew, OA began offering APIs for programmable access to user-requested subsets of ICESat-2 data. NASA’s Distributed Active Archive Center (DAAC) at the National Snow and Ice Data Center (NSIDC) has made migration of ICESat-2 data into NASA’s Earthdata Cloud [2] a priority, thereby establishing a roadmap for cloud-optimized data services facilitating wide accessibility and demonstrated value for users in a cloud environment. OpenAltimetry, which was developed independently of NASA’s Earth Observing System Data and Information System (EOSDIS), is likewise being migrated into the Earthdata Cloud, a pathfinding effort in technology infusion for NASA. At the same time, OpenAltimetry continues to add new functionality in response to users’ needs and has prototyped the addition of data from the Global Ecosystem Dynamics Investigation (GEDI) mission. This presentation will highlight the processes employed, and challenges encountered in bringing OpenAltimetry and ICESat-2 data into the cloud.
