Advanced Weather Interactive Processing System

From Wikipedia, the free encyclopedia

The Advanced Weather Interactive Processing System (AWIPS) is a technologically advanced information processing, display, and telecommunications system that is the cornerstone of the United States National Weather Service's (NWS) modernization and restructuring. AWIPS is an interactive computer system that integrates all meteorological and hydrological data, and all satellite and radar data and enables the forecaster to prepare and issue more accurate and timely forecasts and warnings. AWIPS has been implemented so the NWS will meet its mission "to provide weather and flood warnings, public forecasts, and advisories for all of the United States, its territories, adjacent water and ocean areas, primarily for the protection of life and property" more efficiently and effectively.

The primary tool used in AWIPS is D2D (Display Two Dimensions), a graphical software application that incorporates most available weather information into an easy-to-use interface. Graphical forecasts that NWS forecasters issue to form the National Digital Forecast Database (NDFD) are composed with the Graphical Forecast Editor (GFE), another independent software application running on AWIPS.

AWIPS was originally developed and maintained by PRC, Inc. As of August 2005, the National Weather Service awarded the new maintenance and operation contract of AWIPS to Raytheon Technical Services Company LLC. It is a five year contract with five one-year award terms for a potential maximum 10 year contract.
