To improve future collaboration and data sharing between NASA and the European Space Agency (ESA), the Interagency Implementation and Advanced Concepts Team (IMPACT) worked with ESA counterparts to develop infrastructure to support transferring data at the petabyte scale. On February 3rd, IMPACT initiated transfer of nearly 6 PB of archived Sentinel-2 data to support historical processing of the Harmonized Landsat Sentinel-2 Sentinel-2-based data product (HLSS30). Outcomes from the transfer study address two major needs for NASA: 1) a complete HLSS30 archive back to November 2015—a 2-fold increase in the HLSS30 data volume and 2) a deployable infrastructure for NASA and ESA to transfer data between the agencies at up to 20 GB/s supporting petabyte-scale data exchange in weeks/months. Transfer of the 6 PB of Sentinel-2 data is expected to complete in April and May and will serve as a benchmark for future data exchanges between the agencies.
