Actual evapotranspiration (ETa) from 2001 to 2019 for the Isa GBA region

\n## **Abstract** \nThis dataset was produced by the Geological and Bioregional Assessment Program to assess vegetation water use characteristics in the Isa 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 https://www.tern.org.au/news-australia-wide-aet-data/) 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.\n\n\n## **Attribution** \nGeological and Bioregional Assessment Program\n\n\n## **History** \nThis dataset contains the Landsat-MODIS blended 8-day AET images for the Isa 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 This dataset has been superseded by the updated TERN AET dataset (see https://www.tern.org.au/news-australia-wide-aet-data/) but is still valid for use in analysis.

## **摘要**
本数据集由地质与生物区域评估项目（Geological and Bioregional Assessment Program）制作，旨在评估艾萨GBA区域内的植被水分利用特征。本衍生数据集的制作流程详见本元数据声明中的“历史”字段。本数据集基于中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer, MODIS）实际蒸散量（Actual Evapotranspiration, ETa）影像与陆地卫星（Landsat）影像制作完成。更新后的陆地生态系统研究网络（Terrestrial Ecosystem Research Network, TERN）实际蒸散量（Actual Evapotranspiration, AET）数据集（详见https://www.tern.org.au/news-australia-wide-aet-data/）实现了多项关键改进，因此取代了为GBA项目开发的Landsat-MODIS融合式AET数据集。不过GBA AET数据集仍可用于分析工作。本数据集包含详细的元数据声明，其中涵盖了原始数据集的技术细节。

## **历史**
本数据集包含2000年2月至2018年9月期间艾萨GBA区域的Landsat-MODIS融合式8日合成AET影像。主要源数据集包括：1）由澳大利亚联邦科学与工业研究组织土地与水分部（CSIRO Land and Water）基于8日合成MODIS c6产品生成的AET影像；2）由澳大利亚地质调查局（GA）数据立方体托管于国家计算基础设施（NCI）的Landsat反射率影像。本数据集已被更新后的TERN AET数据集（详见https://www.tern.org.au/news-australia-wide-aet-data/）取代，但仍可用于分析工作。
