Dataset: Actual evapotranspiration (ETa) from 2001 to 2019 for the Beetaloo GBA region



This dataset was produced by the Geological and Bioregional Assessment Program to assess vegetation water use characteristics in the Beetaloo GBA region. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement. This dataset was produced from MODIS ETa images and Landsat images. The updated TERN AET dataset (see has several key improvements implemented which means it supersedes the Landsat-MODIS blended AET developed for the GBA Program. The GBA AET data are still valid for use in analysis. This dataset contains a detailed metadata statement, including technical details regarding the original dataset.

This dataset contains the Landsat-MODIS blended 8-day AET images for Beetaloo GBA Region from Feb 2000 to Sep 2018. The main source datasets include 1) AET images derived from 8-day MODIS c6 product by CSIRO Land and Water, 2) Landsat reflectance images provided by GA Datacube on NCI. This data set has been superseded by the updated TERN AET dataset (see but is still valid for use in analysis.
