This page has been created to help in the preparation of the U.S. Drought Monitor. (The graphics linked to from this page are operational products produced by several different organizations and agencies. The quality control applied to these graphics varies from graphic to graphic and some of the graphics are experimental.) Some of the indicators that are examined to produce the U.S. Drought Monitor include the following:
