1. 3-D rendering of jet stream with temperature on Earth’s surface ESIP Air Domain Overview The Air Domain encompasses a variety of topic areas, but its focus is those areas where the Earth's atmosphere is the primary consideration. These areas include meteorological and weather studies, climate studies, air quality measurements and investigations, and atmospheric chemistry questions that extend through the stratosphere, and probably can be extended to include the implications of near space weather in the ionosphere.

Okay to camp? Weather safety (e.g., air quality and UV) Decision makers: Snow removal, work scheduling, road closures, drought assessment, air quality, water resource management Builders: Excessive eastern rains have kept many builders behind schedule Aviation: Airport delays, safety NASA: Shuttle launches Insurance companies: Claims settlement, severe loss probability Emergency managers: Hurricane evacuation, forest fire evacuation Forestry folks: Fire fighting, fire detection Farmers: Planting, harvesting, spread of insects Energy companies: Managing energy supplies Shipping companies: Storms, waves, etc. Sporting events: Outdoor venues, snowmaking decisions Weather station in the field Oblique 3D view of Jet Stream at 50 m/sec and wind speed plan view at 250 mb Global infrared image and topography composite Questions and Issues Can data sources needed by the Atmospheric Sciences community be prioritized? How important is it to have access to data in near- realtime? What is the best way to integrate, store, and provide access to the data that will result from the interaction of traditional GIS datasets and the spatial and temporal scales of atmospheric science observations? Will emerging standards for web services (e.g., OpenGIS and ISO TC211) be adequate to represent and serve data from atmospheric science data systems? Which tools are best suited for analyzing and displaying atmospheric data and for integrating them with data from related disciplines? What's the best approach to making data available for assimilation into local models? How can we define the goals of cataloging and distributing realtime and retrospective observational and model/assimilation datasets within the context of Digital Libraries? Data Types AERI GOES and polar orbiting satellites LIDAR Lightning detection networks Output from forecast models Radar systems Rainfall data Sea surface temperature Snow cover Space weather data Traditional weather station measurements around the globe Vertical profiles gathered from balloon soundings, aircraft-borne instruments, and wind profiler networks
