Copernicus/Sentinels data processing
The Australian research community has now access to the full set of observations from the new European Copernicus satellite missions, the “Sentinels”. This is possible through “Copernicus Australia”, which is a regional data hub supporting all potential users in our region.
We have taken advantage of this priviledged access to start developing tools for processing observations from the Sentinel3-OLCI and Sentinel2-MSI instruments in particular.
This capability is illustrated below with maps of the phytoplankton chlorophyll concentration around Australia, from the OLCI instrument. These maps display the average concentration for April (top) and June (bottom) 2019, and were obtained through processing of about billions pixels using Pawsey computing resources and the Australia “Copernicus data Hub”.
This is work in progress (some improvements needed for cloud masking), and you can contact us if you have questions about this development
