NIDIS: Expanded Drought.gov Tool Visualizes Historical Drought Conditions by County, State

NIDIS: Expanded Drought.gov Tool Visualizes Historical Drought Conditions by County, State. “The U.S. Drought Portal’s Historical Data and Conditions Tool allows users to visualize historical drought data for their state or county through an interactive map and time series graph. Recently, NOAA’s National Integrated Drought Information System (NIDIS) partnered with NOAA’s National Centers for Environmental Information (NCEI) to expand and improve this interactive tool—making it easier to visualize and share historical data for use in communications, research, or decision-making.”
