  2. A 20/20 Vision (Weather in Our Palm) By the year 2020, mankind will have the technology (observations and models) to digitize the earth’s surface and its atmosphere with a resolution of 1 km and 1 minute And Every individual on earth will have personal and timely access to weather observations and accurate weather forecasts through a “palm” computer/display unit.

  3. Vision Requirements Sensor/Communications/Computational Web • Global continuous earth observing system • Computer system capable of continuous real-time 4-d assimilation of global data to create a “Digital Earth” • Accurate model of the Earth system • Global real-time data/information delivery system • Personal (i.e., hand held) data access and display system

  4. ESE Vision Sensor Web • Low Earth Orbiting: • Global coverage • High spatial resolution • Microwave sounding • GPS density profiles • LIDAR for winds, H2O, O3, CO2 • Geostationary Earth Orbiting: • High temporal resolution (weather dynamics) • Tracer wind velocities • Synergism with ground-based observations • Lightning and microwave precipitation
