•Drought index based on remote sensing data can facilitate dynamic drought assessment.•ET Deficit Index (ETDI) was applied, integrated with vegetation and ET information.•Spatiotemporal changes in ETDI agreed well with the 5-month SPI and PDSI.•ETDI can capture better cropland areas subject to droug...
