The Land Surface Temperature (LST), vegetation status, and soil moisture content are the most important indicators of dryness. In this study, these three variables were used to develop a new dryness index. The index was then compared to the Perpendicular Drought Index (PDI), Modified Perpendicular Drought Index (MPDI), as well as Temperature-Vegetation Dryness Index (TVDI). Among the evaluated indices, the proposed index showed the highest accuracy. The reason was that the proposed index took into account all important variables for dryness estimation. In addition, a dryness map of Iran was produced by applying the proposed index on the MODerate Resolution Imaging Spectrometer (MODIS) data to show the high performance of the proposed index in large scale applications.
