This book was released on 2018-10-25 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proposed research involves the application of multispectral satellite data in combination with ground truth measurements to monitor surface properties of the Greenland Ice Sheet which are essential for describing the energy and mass of the ice sheet. Several key components of the energy balance are parameterized using satellite data and in situ measurements. The analysis will be done for a ten year time period in order to get statistics on the seasonal and interannual variations of the surface processes and the climatology. Our goal is to investigate to what accuracy and over what geographic areas large scale snow properties and radiative fluxes can be derived based upon a combination of available remote sensing and meteorological data sets. Operational satellite sensors are calibrated based on ground measurements and atmospheric modeling prior to large scale analysis to ensure the quality of the satellite data. Further, several satellite sensors of different spatial and spectral resolution are intercompared to access the parameter accuracy. Proposed parameterization schemes to derive key component of the energy balance from satellite data are validated. For the understanding of the surface processes a field program was designed to collect information on spectral albedo, specular reflectance, soot content, grain size and the physical properties of different snow types. Further, the radiative and turbulent fluxes at the ice/snow surface are monitored for the parameterization and interpretation of the satellite data. The expected results include several baseline data sets of albedo, surface temperature, radiative fluxes, and different snow types of the entire Greenland Ice Sheet. These climatological data sets will be of potential use for climate sensitivity studies in the context of future climate change. Steffen, K. and Abdalati, W. and Stroeve, J. and Key, J.

Download or read book Meteorological Processes Controlling the Variability of Net Annual Accumulation Over the Greenland Ice Sheet written by Deborah J. Bathke and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Climatic information available from the spatially extensive suite of firn and ice cores collected under the Program for Arctic and Regional Climate Assessment (PARCA), in conjunction with other data, provides an unparalleled opportunity to investigate accumulation changes over the Greenland ice sheet and to assess its ability to record and preserve a history of North Atlantic climate variability. The ice core derived accumulation histories demonstrate that the influence of glaciological noise on the climate signal is strongly influenced by the accumulation rate. Thus, it may be difficult to discern regionally representative climate signals from individual cores at lower accumulation sites on short time scales suggesting that either time or spatial averaging of the records is necessary. Individual rotated principal components analysis (RPCA) on the time series of net annual accumulation, the total concentration of insoluble dust particles, and the (delta)18O annual average and seasonal extrema reveal that cores located in different regions of the ice sheet do not vary consistently for the period of record in this study (1965-1996). Specifically, cores from southern Greenland vary in a manner different from those in the central west region. Thus, proxy climate histories drawn from a single core record are not necessarily representative of the entire ice sheet. Comparison of the scores associated with the central west and southern Greenland spatial patterns with atmospheric and oceanic data suggest that different processes may be responsible for delivery of precipitation to each region. Correlations of the North Atlantic Oscillation with the core data, combined with composites of mean sea level pressure and 500 hPA heights for accumulation extremes, suggest a negative relationship with the central west region during winter, spring, and summer. Conversely, the same analyses for the southern region suggest a positive relationship to the NAO during summer. Accumulation in the central west region is likely influenced by the NAO during winter and spring, as well as by associated changes in surface temperatures over Canada and sea surface temperatures in the Baffin Bay/Davis Strait. Alternatively, accumulation in southern Greenland is consistently associated with changes in the Pacific.

Evidence of unexpected rates of change in Arctic sea-ice extent, ocean acidification, and species loss emphasizes the urgency needed to develop management strategies for addressing climate change.
Download or read book Climate Change in the Polar Regions written by John Turner and published by Cambridge University Press. This book was released on 2011-05-12 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The polar regions have experienced some remarkable environmental changes in recent decades, such as the Antarctic ozone hole, the loss of large amounts of sea ice from the Arctic Ocean and major warming on the Antarctic Peninsula. The polar regions are also predicted to warm more than any other region on Earth over the next century if greenhouse gas concentrations continue to rise. Yet trying to separate natural climate variability from anthropogenic factors still presents many problems. This book presents a thorough review of how the polar climates have changed over the last million years and sets recent changes within a long term perspective. The approach taken is highly cross-disciplinary and the close links between the atmosphere, ocean and ice at high latitudes are stressed. The volume will be invaluable for researchers and advanced students in polar science, climatology, global change, meteorology, oceanography and glaciology.

This book was released on 2019-06-18 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities â€" social, economic, security, and more â€" that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space (National Academies Press, 2018) provides detailed guidance on how relevant federal agencies can ensure that the United States receives the maximum benefit from its investments in Earth observations from space, while operating within realistic cost constraints. This short booklet, designed to be accessible to the general public, provides a summary of the key ideas and recommendations from the full decadal survey report.
