Drought indices,
Drought indices are widely used for drought monitoring. This study evaluates the performance of six indices (Palmer’s Drought Severity Index (PDSI), Palmer’s Z-index, precipitation percent normal, precipitation percentiles, Standardized Precipitation Index (SPI), and the Standardized Precipitation Evapotranspiration Index (SPEI)) to determine which are most appropriate for monitoring agricultural drought in the south-central United States. Soil moisture and crop yield data for winter wheat, corn and cotton are used to assess the performance of drought indices. The results indicate that SPEI is the most representative of soil moisture conditions. The best drought index for crop yield varies depending on crop type...

South Central CASC
The south central U.S. is one of the main agricultural regions in North America and annual agricultural production is valued at more than $44 billion dollars. Climate variability and drought have both direct and indirect impacts on agriculture and consequences for land management. There are many different drought monitoring products and tools available, but unfortunately most were developed without input from the stakeholders who are intended to use them. In the SC CSC region private landowners, such as farmers and ranchers, are responsible for the majority of land management. The goal of this project is to assess the information needs of famers and ranchers in the SC CSC region in the development of drought monitoring...

Droughts,
There are a variety of metrics that are used to monitor drought conditions, including soil moisture and drought indices. This study examines the relationship between in situ soil moisture, NLDAS-2 soil moisture, and four drought indices: the standardized precipitation index, the standardized precipitation evapotranspiration index, the crop moisture index, and the Palmer Z index. We evaluate how well drought indices and the modeled soil moisture represent the intensity, variability, and persistence of the observed soil moisture in the southern Great Plains. We also apply the drought indices to evaluate land–atmosphere interactions and compare the results with soil moisture. The results show that the SPI, SPEI, and...
