IGARSS 2002 June 24, NASA Earth Science Research Priorities availability of water –under the stress of long term climate changes, intra-seasonal to seasonal weather and climate variability –no current theoretical basis to explain major changes in weather on these scales. predictability of tropical storms –track and intensities, ecological forecasting –species identification and changes, linkage between sea level and changes in climate –and other aspects of the Earth system.

IGARSS 2002 June 24, NASA Earth Science Additional Research Topics understanding the hydrologic cycle –under the effects of the changing climate; ecosystem health –biodiversity changes and invasive species; severe storm systems –tornado, hail, winter snow and ice storms; forecasting earthquakes and volcanoes

IGARSS 2002 June 24, NASA Earth Science Observational Requirements Measure atmospheric and oceanic circulation systems –circulation and causes of variability –transport of heat –in atmosphere: profiles temperature, humidity, and winds atmospheric chemical constituents aerosol loading Measure at temporal and spatial scales appropriate to the physical processes. availability of water –relation to long- term climate change intra-seasonal climate variability –causes, predictability tropical storms –predictability

IGARSS 2002 June 24, NASA Earth Science Observational Requirements Measure full hydrologic cycle –response to climate change Measure –precipitation –evaporation –clouds –cycling through ground and surface water flow –ground water storage –ocean circulation, SST, topography and salinity –ice and frozen surfaces Measure at temporal and spatial scales appropriate to the physical processes. availability of water –relation to long- term climate change intra-seasonal climate variability –causes, predictability tropical storms –predictability ecological forecasting sea level linkage to climate

IGARSS 2002 June 24, NASA Earth Science Observational Requirements Measure Earth’s land and ocean surface: –surface topography –surface temperature, humidity, roughness –boundary layer depth –atmosphere - ocean fluxes –ice and frozen surfaces. Measure at temporal and spatial scales appropriate to the physical processes. availability of water –relation to long- term climate change intra-seasonal climate variability –causes, predictability tropical storms –predictability ecological forecasting sea level linkage to climate

IGARSS 2002 June 24, NASA Earth Science Modeling Requirements four dimensional, ensemble models –numerical framework within which new theories can be developed, tested and improved improved atmospheric and ocean model physics –sub-grid scale parameterizations of the hydrological, turbulent and air- sea/land-sea interaction. ability to model and map biological resources, –biological structures, functional capability, physiological state, biological production mapping, etc. modeling at temporal and spatial scales appropriate to the physical processes.
