An Objective Seasonal Drought Outlook for the Coterminous United States

NIDIS Supported Research
NIDIS-Supported Research
Main Summary

This project advances the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center's (CPC's) operational capabilities for prediction of drought to develop an objective drought seasonal outlook (ODSO). This project will utilize various datasets like precipitation, temperature, soil moisture, snow-water equivalent, and others to develop the ODSO. This project will be readily transferrable to operations and will implement a prototype system at CPC that will draw from the operational North American Land Data Assimilation System (NLDAS) and will produce information for CPC Drought Outlook forecasters in near real time.
