AusENDVI (Australian Empirical NDVI) is a monthly, 5-km gridded estimate of NDVI across Australia from 1982-2022. It is built by calibrating and harmonising NOAA's Climate Data Record AVHRR NDVI data to MODIS MCD43A4 NDVI using a gradient boosting ensemble decision tree method. Additionally, the datasets are gapfilled using a machine-learning derived synthetic NDVI dataset.
The methods are extensively described in an Earth System Science Data publication
