Validation Summary: 
General Comments:Historical soil moisture and evaporaton simulated by Narasimhan et al. (2005) was used in this study to develop the agricultural drought indices. Soil moisture and ET were simulated for a 16 km^2 resolution. A soil moisture deficit index (SMDI) and evapotranspiration deficit index (ETDI) were developed from the simulated data. The predicted SWAT soil moisture was postively correlated with NWDI for agriculture and pastureland cover types (r ≈ 0.6).
