Weather-based decision support systems

Definition

Weather-based decision support systems (WDSS) are tools that utilize meteorological data to help users make informed decisions regarding activities that can be affected by weather conditions. These systems incorporate real-time weather information, forecasts, and predictive models to assist farmers, agricultural managers, and policymakers in optimizing crop management strategies and resource allocation. By integrating various data sources, WDSS can enhance the efficiency of agricultural operations and minimize risks associated with adverse weather events.
