Night Vision Goggles Operations Weather Software (NOWS)

This report summarizes progress on the development of NYG Operations Weather Software (NOWS) from September 1997 through August 1998. NOWS is designed for use by DoD meteorologists to support forces performing covert operations using NVGs. The types of missions that are supported include helicopter refueling, target acquisitiondetection, take-off and landing, identification of pickup/drop zones, and search and rescue. NYG performance predictions are made for specified missions and forecasted local weather conditions. NOWS also provides solar and lunar ephemeris information for a series of times or dates at a user-specified location. NOWS is being developed incrementally to include state-of-the-art physical models, a modem graphical user interface, and access to geographic and meteorological databases to provide accurate results, maximize usability, and minimize the amount of input data that must be entered manually by a user, This report describes progress made in the areas of NOWS system design, user interface, physical models, and model assessment.
