Environmental satellites provide data that are used for forecasting the weather, measuring variations in climate over time, and predicting space weather. In planning for the next generation of these satellites, federal agencies originally sought to fulfill weather, climate, and space weather requirements. However, in 2006, federal agencies restructured two key satellite acquisitions. This involved removing key climate and space weather instruments. This report: (1) assessed plans for restoring the capabilities that were removed from the two key satellite acquisitions; and (2) evaluated federal efforts to establish a strategy for the long-term provision of satellite-provided space weather, and climate data. Charts and tables.

Environmental Satellites: Strategy Needed to Sustain Critical Climate and Space Weather Measurements

The U.S. Government Accountability Office (GAO) is an independent agency that works for Congress. The GAO watches over Congress, and investigates how the federal government spends taxpayers dollars. The Comptroller General of the United States is the leader of the GAO, and is appointed to a 15-year term by the U.S. President. The GAO wants to support Congress, while at the same time doing right by the citizens of the United States. They audit, investigate, perform analyses, issue legal decisions and report anything that the government is doing. This is one of their reports.

Thisinvolved removing key climate andspace weather instruments.GAO was asked to (1) assess plansfor restoring the capabilities thatwere removed from the two keysatellite acquisitions, (2) evaluatefederal efforts to establish astrategy for the long-term provisionof satellite-provided climate data,and (3) evaluate federal efforts toestablish a strategy for the longtermprovision of satellite-providedspace weather data. To do so, GAOanalyzed agency plans and reports.

Understanding the effects of natural and human-induced changes on the global environment and their implications requires a foundation of integrated observations of land, sea, air and space, on which to build credible information products, forecast models, and other tools for making informed decisions. The 2007 National Research Council report on decadal survey called for a renewal of the national commitment to a program of Earth observations in which attention to securing practical benefits for humankind plays an equal role with the quest to acquire new knowledge about the Earth system. NASA responded favorably and aggressively to this survey, embracing its overall recommendations for Earth observations, missions, technology investments, and priorities for the underlying science. As a result, the science and applications communities have made significant progress over the past 5 years. However, the Committee on Assessment of NASA's Earth Science Program found that the survey vision is being realized at a far slower pace than was recommended, principally because the required budget was not achieved. Exacerbating the budget shortfalls, NASA Earth science programs experienced launch failures and delays and the cost of implementing missions increased substantially as a result of changes in mission scope, increases in launch vehicle costs and/or the lack of availability of a medium-class launch vehicle, under-estimation of costs by the decadal survey, and unfunded programmatic changes that were required by Congress and the Office of Management and Budget. In addition, the National Oceanic and Atmospheric Administration (NOAA) has made significant reductions in scope to its future Earth environmental observing satellites as it contends with budget shortfalls. Earth Science and Applications from Space: A Midterm Assessment of NASA's Implementation of the Decadal Survey recommends a number of steps to better manage existing programs and to implement future programs that will be recommended by the next decadal survey. The report also highlights the urgent need for the Executive Branch to develop and implement an overarching multiagency national strategy for Earth observations from space, a key recommendation of the 2007 decadal survey that remains unfulfilled.

Climate change poses risks to many environmental and economic systems, including agriculture, infrastructure, and ecosystems. This report examines: (1) federal funding for climate change activities and how these activities are organized; (2) the extent to which methods for defining and reporting climate change funding are interpreted consistently across the federal government; (3) federal climate change strategic priorities, and the extent to which funding is aligned with these priorities; and (4) what options, if any, are available to better align federal climate change funding with strategic priorities. Includes recommendations. Charts and tables. This is a print on demand edition of an important, hard-to-find publication.
