The United States continues to experience drought and, as a result, suffers significant economic losses. The U.S. Drought Monitor, developed in 1999 as an experimental product by the NDMC, USDA, and NOAA, has become an operational product that has gained widespread acceptance by scientists, resource managers, policy makers, the business community, and others. The success of this product depends on the collaboration between the principal partners and other organizations, including the user community, and the integration of several climate and water supply indices and other climate parameters into a weekly assessment of drought severity and spatial extent. The Drought Monitor map and the procedures used in its production are transferable to other drought-prone regions, with appropriate modifications.
