This resource provides the global estimates of Flash Drought Stress Index (FDSI) from 31<sup>st</sup> Match 2015 through 19<sup>th</sup> March 2019 at a daily time-step at 36-km spatial resolution. FDSI non-linearly combines Soil Moisture Stress (SMS, drought stress) and the Relative Rate of Drydown (RRD, drought stress intensification rate). SMS and RRD are developed using SMAP<em> θ<sub>RS</sub></em> (March 2015-2019) and footprint-scale seasonal soil water retention parameters and land-atmospheric coupling strength. The value of FDSI ranges between (0, 1) with values >0.71 indicates flash drought conditions. For details, the readers are referred to the <strong>read.me.pdf</strong>.
