PEPS

1. PEPS French Access to Copernicus Space Data

2. PEPS – 04 - 12 - 2018 What’s PEPS today • 3 main functions: • "Mirror site" of ESA hubs providing access to Sentinel 1, 2 and 3 products • Automatic download to multiple ESA hubs in parallel (delay <48h) • Full archive – except S3: only up to 15th April 2019 • Processing workshop allowing "first level" treatments, results visualization and products downloading • New version releasedin June 2018 and progressivelyenriched • Incubation of relatively "mature" processing chains for "scale" validation • 5 companies hosted on the CNES computer center + 2 science laboratories Direction du Numérique, de l'exploitation et des Opérations

3. PEPS – 04 - 12 - 2018 Active treatments in PEPS • Several standard tools: streaming visualization, NDVI, color compositions… • Dedicatedtreatmentsrequired by someusers • Flagshiptreatments(based on CNES tools) • Orthorectification of S1 products vs the S2 grid • S2 groundreflectanceusing MAJA • Unitary but also multidate processing(full Ortho and full Maja…) • Use of WPS protocol • In progress: • S2 correlation • S1 interferometry • Soil moisture product mixing S1 and S2 data Direction du Numérique, de l'exploitation et des Opérations

4. Near Data Processing PEPS provide online processingfacilities Applications are provided by CNES or by users This featuresimplify the discovery and the use of the information in the spatial data Direction du Numérique, de l'exploitation et des Opérations

5. User uptake and Incubation • After agreement, PEPS host companieswhowant to develop and improve a spatial service • The hosting infrastructure isbased on WPS, DOCKER and PROACTIVE metascheduler • The data are stored close to the HPC/HPDA 9.5 PB Direction du Numérique, de l'exploitation et des Opérations

6. PEPS – 04 - 12 - 2018 PEPS linkwithThematic Data Centers / hubs • MUSCATEenvironmentuses PEPS catalog and accessdirectly to the products • For Theia (Land Surface Thematic Data and Services Center) • systematic MAJA processing over France, northAfrica… • + snowdetection, monthly L3A synthesis, land cover… • http://www.cesbio.ups-tlse.fr/multitemp/?p=14600 • For Form@ter(Solid EarthThematicData and Services Center) • systematicinterferometryprocessing over large areas • SPOT archive • Provideaccess to SPOT data to completeSentinel2 time series(SWH processing) Direction du Numérique, de l'exploitation et des Opérations

7. PEPS – 04 - 12 - 2018 Data storage • Volume of stored data • ≈ 9.5 PB - around 4 PB in line • 14,175,000 products • Availablestoragecapacity: 14 PB • Logic for storage: • Oldest data are transferred to tape storagedevices (longer delay for data retrieving) • Sentinel-3 products are systematicallytransferredafter a few days • Easy upgrade for storagecapacity if needed • Good margin in the capacitiesdedicated for usersprocessing DIrection du Numérique, de l'exploitation et des Opérations
