Can We Use Satellite-Based FAPAR to Detect Drought?

摘要: Drought in Australia has widespread impacts on agriculture and ecosystems. Satellite-based Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) great potential to monitor assess drought vegetation greenness health. Various FAPAR products based satellite observations have been generated made available the public. However, differences remain among these datasets due different retrieval methodologies assumptions. The Quality Assurance for Essential Climate Variables (QA4ECV) project recently developed a quality assurance framework provide understandable traceable information (ECVs). QA4ECV is one ECVs. aim this study investigate capability monitoring Australia. Through spatial temporal comparison correlation analysis with widely used Moderate Resolution Imaging Spectroradiometer (MODIS), Satellite Pour l’Observation de la Terre (SPOT)/PROBA-V by Copernicus Global Land Service (CGLS), Standardized Precipitation Evapotranspiration Index (SPEI) index, as well European Space Agency’s Change Initiative (ESA CCI) soil moisture, shows that can support agricultural assessment reliable uncertainties associated valuable applications use dataset future.
