Full description

Products outputs produced by CSIRO from the H2020 PrimeWater project for the Melbourne Water's Western Treatment plant at Werribee, Victoria, Australia.
Lineage: The aLMI code was installed on the CSIRO EASI platform (https://research.csiro.au/cceo/underpinning-technologies/earth-analytics/ ) and applied to the two Australian study sites using the multispectral Sentinel-2 and Landsat-8 analysis ready data (ARD) surface reflectance data publicly available on the Digital Earth Australia. The aLMI model was applied to the Sentinel-2 and Landsat 8 Analysis Ready Data (ARD) parameterised using SIOP sets from Lake Hume and the WWTP sites. Eight SIOP sets were provided to the model for Lake Hume and WWTP runs respectively. In each case, inversion runs for each site were conducted using the SIOP sets measured at the water body. The aLMI code retrieves simultaneous concentration estimations of chlorophyll-a and Non-algal Particulates (NAP), Colour Dissolved Organic Matter absorption (aCDOM(440nm)), Vertical Attenuation coefficient Kd(490nm) and Secchi Disk Depth (SDD). Additional parameters can be output if required, including:
•\tDiffuse extinction coefficient (PAR)
•\tTotal, Phytoplankton and NAP absorption
•\tPhytoplankton, Particulate & NAP backscattering
•\tModel closure
