The Drought Risk Atlas provides historic data about drought for weather stations across the United States that have at least 40 years of records. Users can select a station and view data for several drought indices over time, frequency statistics for drought thresholds, drought period information, and index comparisons.
Where do these data come from?
The Drought Risk Atlas uses precipitation records from the National Weather Service Cooperative data (COOP) that is archived by the Regional Climate Centers (RCC) in their Applied Climate Information System (ACIS).
