Research and pre-production data sets
Data is produced by CSIRO using the pre-operational system on the NCI. Users with access to the NCI filesystem (i.e. NCI registered users) can access the data there. Contact the CSIRO eReefs team for further details.
Data is progressively transferred from the NCI and made available at the CSIRO THREDDS server. Data comprises mapped images of satellite surface reflectances, retrieved concentrations and various ancillary data and metrics. There is one image per satellite overpass, typically one per day, but sometimes two depending on the satellite ground track with respect to the GBR. MODIS and VIIRS time series are stored in separate hierarchies on the THREDDs server. The data can be visualised using the GODIVA viewer link that appears in the list of services for each data file.
Note that most pre-production testing of the system has been undertaken using 2014 as an exemplar year, as it lies within the lifetimes of both the MODIS and VIIRS missions, and is not too soon after the VIIRS launch (2011) when the sensor calibration may be changing more quickly. For this reason, initially only 2014 data is available from the CSIRO system, but this will very soon extend to cover the lifetime of both missions (for MODIS, back to September 2002).
Production data sets
The Bureau of Meteorology operates the production system and also makes its data archive accessible via a THREDDS data server. That service underpins the web map-based interface, which is the Marine Water Quality Dashboard
As at February 2016, the Bureau system is continuing to run the processing system developed in the first stage of eReefs (2012-2013). Over the course of the first half of 2016, the Bureau will upgrade to run the new extended system developed by CSIRO, and once tested and verified to be running stably, the Bureau will make available production data from that system.
