The storage backbone of EODMS is CCMEO’s Multi-Mission Archive (MMA) which is the Canadian authorised repository of over 1PB of RADARSAT-1, RADARSAT-2, RCM, NAPL and NMSO commercial imagery. The capacity of the archive is currently 4 PB and growing. The data is stored robustly using redundant storage and securely to comply with RSSSA laws on access controls and dissemination.

ENVIRONMENT CANADA - CANADIAN ICE SERVICE
[1] The Climate Processes Section within the Climate Research Division currently uses Sentinel-1 EW GRDM for researching Arctic sea ice dynamics and melt processes. As part of our analyses, we also generate a variety of sea ice motion datasets (e.g. automated daily Pan-Arctic motion, sub-daily regional AOIs) for collaborators working in Government Operations/Research as well as Academic Research.
[2] Having access to the high-speed connection is critical for the timeliness of the analysis and ice motion products generated in addition to maintaining the capacity to keep pace with the rate of SAR data acquisition. With the previous connection the delay between image download, analysis and product generation was a large bottleneck whereas with DHUS National Mirror access we can automate same-day or 1-day-previous sea ice motion products at Pan-Arctic scale. Pan-Arctic processing was basically impossible using the Copernicus Open-Access hub due to the transfer rate bottleneck and cloud-rehosted S1 data collections at the time were not a solution as access to the L1 GRD products was required.
DEFENSE RESEARCH
[1] On behalf of operational partners within DND, DRDC Ottawa uses Sentinel-1 data acquired over the SOIN (Spaceborne Ocean Intelligence Network) area-of-interest off the coast of Halifax, in developing tools for: 1) ocean feature detection and analysis; and 2) ship detection and surveillance. In both cases, the Sentinel-1 images and the Sentinel-1 level-2 radial velocity (RVL) products are used and evaluated in synergy with RADARSAT-2 (and soon RCM) imagery.
[2] DHUS National Mirror services are required for three reasons: 1) due to network architecture, the division has difficulty in accessing both the Copernicus Open hub and the API hub; 2) the division downloads hundreds of S1 image frames per month requiring high-speed internet access; and, 3) the division does not have staff resources to manage and create our own automatic downloading service from the Copernicus data hub.
