Quantifying the Relative Importance of Multiple Drought Indicators in the U.S. Drought Monitor as a Function of Location and Time of Year

NIDIS Supported Research
NIDIS-Supported Research
Main Summary

The goal of this project is to determine the roles of multiple physical indicators in replicating the drought conditions in the U.S. Drought Monitor (USDM) and quantify the information explained by each indicator as a function of location and season. Knowledge of this information could eventually lead to customized objective blends for monitoring or more optimized and accurate drought early warning systems (DEWS). If local stakeholders can have information about which drought indicators are most critical for monitoring and predicting evolving droughts in their regions, then they can better prepare for and mitigate existing droughts.

What to expect from this research

The researchers plan to work with the NIDIS Drought.gov team to widely distribute this information, potentially through a web-based drought dashboard that can be used to automatically generate key indicator maps for a location of interested based on findings.
