Developed by Northrop Grumman, the Integrated Meteorological System (AN/TMQ-40 IMETS) is the meteorological component of the Intelligence and Electronic Warfare (IEW) an element of the Army Battle Command System (ABCS). IMETS provides Army commanders at all echelons with an automated weather system to receive, process, and disseminate weather observations, forecasts, and weather and environmental effects decision aids to all Battlefield Operating Systems (BOS). IMETS is a mobile, tactical, automated weather data receiving, processing and dissemination system. The IMETS is an Army-furnished and maintained system operated by US Air Force battlefield weather team personnel. It uses US Air Force and Army developed software to provide a total weather system to support the Army. The Integrated Weather Effects Decision Aid (IWEDA) software, originally developed by the U.S. Army Research Laboratory (ARL) in 1992, has been fielded on IMETS since 1997 to provide tactical weather support to the U.S. Army.
