Standardized Dataset of the Ecosystem's Gross Primary Productivity (sGPP) and the Evapotranspiration Deficit Index (SEDI) for 1982–2017 over the Middle East

This data aimed to investigate the spatial-temporal variability of carbon productivity and the Standardized Evapo-transpiration Deficit Index (SEDI). The Middle East (ME), was selected as a case study to monitoring  drought events as one of the major natural disasters for the ecosystem. To this end, the yearly gross primary production of GLASS, GIMMS,  FloxCom, and VPM datasets for the study area spanning 1982–2017 was used to develop the sGPPR data. On the other hand, the Global Land Evaporation Amsterdam Model (GLEAM-version (v3.3a)), which estimated the several components of terrestrial evaporation (annual actual and potential evaporation (AET, PET)) was used for the same period this aimed to detect the variability of the SEDI.
This version of the yearly GLASS-sGPPR dataset (1982–2017) is available for the ME at 0.05° spatial resolution, as the original data of  the GPP-GLASS products, While, sGPPR dataset of GIMMS,  FloxCom, and VPM are also at annual temporal resolution, and at 0.5 degree spatial resolution spanning 1982–2016 for GIMMS,  FloxCom, and 2000-2016 for VPM (Excel wrokbook .xlsx). The SEDI data are also available at 0.25 degree spatial resolution for 1980–2018 ( Raster files (TIFF)).
