From page 1...
... In addition, enhanced physical understanding, new modeling strategies, and powerful computers combine to provide improved atmospheric simulations and predictions. This progress leads the Board on Atmospheric Sciences and Climate (BASC)
From page 2...
... Proposed configurations of the national and international observing systems should be examined with the aid of observing system simulation experiments. In addition, new opportunities for advances in research and services lead to the second imperative: Atmospheric Science Imperative 2: Develop New Observation Capabilities The federal agencies involved in atmospheric science should commit to a strategy, priorities, and a program for developing new capabilities for observing critical variables, including water in all its phases, wind, aerosols, and chemical constituents and variables related to phenomena in near-Earth space, all on spatial and temporal scales relevant to forecasts and applications.
From page 3...
... Critical scientific questions focus on the exchanges of energy, momentum, and chemical constituents between the troposphere and the surface below, as well as with the layers above. Atmospheric Research Recommendation 2: Extend a Disciplined Forecast Process to New Areas A strategy and implementation plan for initiating experimentalforecasts and taking advantage of a disciplined forecasting process should be developed by appropriate agencies and the scientific community for climate variations, key chemical constituents, air quality, and space weather events.
From page 4...
... The emerging issues identified in the recommendation require the attention of atmospheric scientists in a wide range of disciplines and collaborators concerned with human dimensions. RECOMMENDATIONS FOR LEADERSHIP AND MANAGEMENT IN THE ATMOSPHERIC SCIENCES BASC recommends that leadership and management issues related to planning and priorities should be addressed forthrightly by the entire atmospheric science community, including federal agencies, professional societies, and the academic and private sectors.
From page 5...
... Leadership and Management Recommendation 3: Assess Benefits and Costs The atmospheric science community, through the collaboration of appropriate federal agencies and advisory and professional organizations, should initiate interdisciplinary studies of the benefits and costs of weather, climate, and environmental information services. Reasons for examining the benefits and costs of maintaining the atmospheric enterprise are to ensure that funds invested in atmospheric research and services are highly leveraged in serving national interests and to help determine which new directions in atmospheric research and services will provide the most benefit to the public and private sectors.
From page 6...
... For the longer term, they emphasize the resolution of climate variability on the scale of decades to centuries and the possibilities of projecting climate variations. Atmospheric Physics Research Atmospheric physics seeks to understand physical processes in the atmosphere, including atmospheric radiation, the physics of clouds, atmospheric electricity, boundary layer processes, and small-scale atmospheric dynamics.
From page 7...
... The challenge for atmospheric chemistry research in the coming decades is to develop the tools and scientific infrastructure necessary to document and predict the concentrations and effects of these species on local, regional, and global spatial scales and on daily to decadal time scales. These Environmentally Important Atmospheric species are stratospheric ozone, greenhouse gases, photochemical oxidants, atmospheric aerosols, tonics, and nutrients.
From page 8...
... 7. Emphasize tropical cyclone motion and intensity, especially research on the physics of tropical cyclone motion and changes in intensity, research on interactions with the upper ocean layers, and research to delineate optimal combinations of measurement systems for hurricane forecasting.
From page 9...
... The three dominant scientific goals in climate change are: 1. Understand the mechanisms of natural climate variability on time scales of seasons to centuries, and assess their relative significance.
