This dataset blends A soil water time series provides the framework for evaluating, A new agricultural drought index was developed for monitoring drought impacts on agriculture in Oklahoma. A new calculation method is discussed, which provides early information on physical implementation of drought risk levels and improvement in setting up a complex drought monitoring system, which could assist hydrologists, meteorologists and farmers to predict and more precisely quantify the yield loss and the role of vegetation in the hydrological cycle. This study examined the Standardized Precipitation Index (SPI) and Reconnaissance Drought Index (RDI) to determine drought severity in 12 meteorological stations in southern Iran from 1975-2015 and predict draught transition from The Living Blended Drought Product (LBDP) is a recalibrated data series of June-July-August Palmer Modified Drought Index (PMDI) values in the lower 48 U.S. states.
