• UK-MM-PAC ERS-1/2
– Since 1991 for ERS-1, Astrium GEO (then NRSC Ltd)
have performed Processing and Archiving Facilities
for ESA. In 1994 the facility was expanded to
support ERS-2.
• Archiving of both HR (SAR) and LR (ATSR-1/2, ALT,
GOME, WAVE,SCATT)
• On-Request SAR Processing
• Systematic ALT Processing
– Media types
• Exabyte
• Sony DIR1000
• DLT
• STK9940B
• STK T10KBAstrium GEO UK-MM PDGS Facilities and

• UK-MM-PAC ENVISAT
– In 2002, UK-PAF became UK MultiMission Processing
and Archiving Centre with the addition of ENVISAT
operations
• Archiving of both HR (ASAR) and LR (AATSR, MERIS)
• On-Request ASAR Processing
• Systematic AATSR Processing
• On-Request MERIS Processing
• Systematic MERIS (MER_FRS) Processing
– Current Archive volume ~1.2 PB (Inc. ERS)
– Media types
• IBM NTP
• STK9940B
• STK T10KBAstrium GEO UK-MM PDGS Facilities and

• UK-MM-PAC Data Hosting
– The following datasets are made available to Users
for FTP download
• ATSR-1 (L1B, L2, L2P) ~10TB
• ATSR-2 (L1B, L2, L2P) ~15TB
• AATSR (L1B, L2, L2P) ~22TB
• ERS ALT.WAP ~1TB
• ERS Wind Scatterometer ~1.5TB
• MERIS Reduced Resolution ~45TB
– Users granted access through the eoa-up and ats-
merci-uk servers
– Access via 300 Mbps link
– Additionally, provide backup copy of GEOHAZARD
dataset from CloudAstrium GEO UK-MM PDGS Facilities and

• UK-MM-PAC Data Hosting Continued
– In addition to FTP Access to data, HTTP access to (A)
ATSR and MERIS RR datasets is provided through
two MERCI Servers
• atsr-merci-uk.eo.esa.int
• mer-merci-uk.eo.esa.int
• FTP downloads during Q1 2012 ~75TB

• Future Activities
– SWARM APDF
• Following the launch in Q4 2012, Astrium GEO will
provided operational support for the SWARM Mission
using MMFI infrastructure
– Sentinel-1 Offline PAC
• Astrium GEO will shortly commence site preparation
activities for the Sentinel-1 Mission including the
provision of an LTA facility
• Support will also be provided for the commissioning of
the PDGS following Launch
– Sentinel-2 Offline PAC
• Initial site preparation activities for the Sentinel-2
Mission will also be undertakenAstrium GEO UK-MM PDGS Facilities and
Services
• The Sentinel LTAs will be interfaced to the PAC
infrastructure via a set of web services.
• The LTAs have generic requirements – 30 TB/Day I/O,
transfer rate of min 220 Mbytes/sec, 10,000 files a day and
max file size of 200GBytes.
• The Infoterra LTA for Sentinel 1 consists of
– Web services to realise the interface
– Fast Network Infrastructure
– Disk Cache to support fast IO
– Hierarchical Global File System – to automate the archival and
retrieval of products
– Tape Archive
• Tape Archive to support Long Term Storage
– Tape archive based on i6000 LTO robotics
– Support for all LTO 5,6 products
– Scalable ( 96 Drives – 5300 Slots )
– LTO technology to deliver an Open format and long roadmapAstrium GEO UK-MM PDGS Facilities and

• LTDP Preparations
– The following activities are currently being undertaken
• Reviewing Archive content against catalogue
• Preparation for reading of all Archived media
• Verification of previously transcribed datasets against
transcription records
• Identification of documentation
• Scanning of paper documentation
• Implemented virtualisation of Altimeter processing to
generate ERS-1/2 ALT-WAP products
• Further virtualisation being assessed

• Collaborative Activities
– Working with ISIC – CEMS Project
• The provision of computing
infrastructure for access to large-
volume EO and climate model datasets
co-located with high performance
computing facilities
• Collaboration of Commercial and
academic resources
• Data integrity service and metadata
infrastructure – FP7 Charm project.
• Full vCloud virtualisation for service the
commercial and academic user
communities
• User can ‘bring their own data’ to CEMS
for inclusion in their environment and to
develop ‘mash ups’ using EO data setsYou can also read
