nowcasting techniques would then provide forecasts from a few minutes to many hours. A broad array of products will be used to support decisions that improve safety to humans, improve operational efficiency, and make homeland defense efforts more effective.

Recommendation

To support the use of radar data in the climate observing system and other research areas, standards for calibration and continuity of observations should be established and implemented.

Recommendation

The value of radar data, as part of an integrated observing system, in diagnostic applications, nowcasting systems, and hydrologic and numerical weather prediction models should be considered in the design of the next generation weather radar system. The characteristics of radar observations and associated error statistics must be quantified in ways that are compatible with user community needs.

Recommendation

Plans for next generation weather radar systems should include provisions for real-time dissemination of data to support forecast, nowcast, and warning operations and data assimilation for numerical weather prediction, and certain research applications. Routine reliable data archiving for all radars in the system for research, climatological studies, and retrospective system evaluation must be an integral part of the system. Convenient, affordable access to the data archives is essential.

Recommendation

Tactical Decision Aids and means for collaborative decision-making capabilities should be developed for both meteorological and nonmeteorological users of the system, with attention to the demands on the integrated observing system.
