What’s available from the Hub?
Data use and some application examples
How to access the Hub’s data?
Interest in finding out more and/or participating in future training?

3. What’s the Copernicus Australasia Regional Data Hub?
It’s a repository of satellite data from Sentinel-1, Sentinel-2, and Sentinel-3 from the European Commission’s Copernicus Programme
It syncs, stores and shares Sentinel satellite data processed and stored in Europe over our Region
It uses government research and digital infrastructure:
GEANT and AARNET - to move up to three terabytes of data daily across the globe within 24 hours of satellite acquisition and/or availability
National Computing Infrastructure Australia (in Canberra) - to store the data

4. Established to... run under a series of partnership agreements:
support government research and operational programs that rely on Earth observation data
bring Sentinel data to local computing infrastructure and processing pipelines
enhance access by research, industry and civil society in our Region, and
help facilitate collaboration between Australians, New Zealanders, Europeans and inhabitants of the South Pacific and South-East Asia
run under a series of partnership agreements:
Consortium partners that manage and operate it:
Delivery partners who sync and distribute the data across the globe:
Supporting partners who provide access to the data:

5. What’s available from the Hub?
The Hub’s Region of Interest
Currently:
Sentinel-1, all-weather, day and night radar imagery
Sentinel-2, high resolution optical imagery
Sentinel-3, high accuracy optical, radar and
altimetry data, including Near-Real-Time and derivative:
ocean colour,
land reflectances,
land and sea temperature, and
ocean and land topography products
Coming soon:
Sentinel-5P, a precursor to providing dedicated atmospheric composition monitoring
More to come:
Copernicus Programme aims to operate six families of Sentinel satellites with dozens of contributing space missions.

6. What’s available from the Hub? ...continued
Sentinel imagery, beginning of each mission, providing a rich density of imagery through time:
Sentinel-1 - from 2014 to present
Sentinel-2 - from 2015 to present
Sentinel-3 - from 2016 to present
To-date the Hub has synced over 3.9 Million images and has distributed over 2,100 terabytes of data to users. These numbers increase by three terabytes daily.

7. Sentinel-1 core product range:
The Copernicus Australasia Regional Data Hub:
aims to sync all data within 24 hours of its availability from the European portals/hubs and
is syncing all above products.

The Copernicus Australasia Regional Data Hub aims to sync all data within 24 hours of its availability from the European portals/hubs.

9. Sentinel-1 image over Suva, Fiji
Here’s an example of SAR imagery from Sentinel-1, showing a combination of Single polarisation (vertical), dual polarisation (vertical, horizontal), and ratio of the two. SAR is able to capture day and night, and is not affected by clouds.

10. Sentinel-2 core product range:
Now available from the Copernicus Australasia Regional Data Hub
Will be available in the future from the Copernicus Australasia Regional Data Hub
Not available from European Space Agency
Graphical Representation of SENTINEL-2 Core Products
BOA -> Bottom of Atmosphere TOA -> Top of Atmosphere
In above core product diagram, the Copernicus Australasia Regional Data Hub is only syncing level L1C from Sentinel-2 satellite, and plans to sync level 2 products when they become available, from the European Space Agency (ESA), early next calendar year. The reason L1b is not available from Copernicus Australasia is because it is not available from ESA.

15. Revisit Frequency for Sentinel-1 & 2:
Sentinel-1 constellation offers an improvement in revisit time over ERS-1/2 and ENVISAT ASAR, and a continuity of wide area coverage with ENVISAT ASAR,
Sentinel-1
The Sentinels have a highglobal revisit frequency due to their multiple constellations and their two satellite configurations e.g., Sentinel-3 has Sentinel 3A and 3B.

16. Revisit Frequency for Sentinel-3 instruments:
Sentinel-3 SLSTR instrument mean revisit time with two-satellite configuration, red showing daily revisits at equator and blue less than 0.4 at higher altitudes.
Sentinel-3 - Altimetry subcycle - 4 days - 57 orbits. World Map
Sentinel-3 OLCI instrument mean revisit time with a two-satellite configuration, red showing 2 day revisit at equator and blue less than 0.5 at higher altitudes.

17. Hub is sponsored to support Government programs such as:
Statewide Monitoring Programs
Digital Earth Australia (DEA) Program
LandMonitor
FireWatch Aurora

18. Sentinel applications:
monitor native vegetation changes and woody vegetation extent in support of legislative and regulatory requirements
improve the quantification of ground cover information
model land condition of Great Barrier Reef catchments
map (coal seam gas) physical infrastructures in support of regulatory and activity monitoring
develop methodologies to monitor ground deformation and subsidence
measure natural water flows and monitor water quality both coastal and inland
fire burn scar mapping, fuel loading and modelling of fire behaviour
mapping of broad crop types
respond and recover from disasters
monitor, detect and characterise land, water and infrastructure changes across Australia
contribute to climate impact research and studies
These are Consortium partner applications/uses in the Hub’s ROI.

19. How to access the Hub’s data
Register with SARA at
New Zealand users can register here:
Queries can be constructed in several ways
GUI
API
SARA api (powered by resto), eg
Sentinel-2 Data over Fiji:
Data from all Collections over Fiji (Sentinel-1, Sentinel-2, Sentinel-3):
Auscophub specifically the sara client, highly recommended for regular bulk downloads, and is a Python module which wraps the SARA api interface. eg
auscophub_searchSara.py -q "q=Fiji" --sentinel 2 -q "startDate= " -q "completionDate= " --curlscript curl-script.bash --jsonfeaturesfile feature-file.geojson
The Hub’s portal or access point for getting data is called SARA - Sentinel Australasia Regional Access
