Distributed Active Archive Centers
The Earth Observing System Data and Information System (EOSDIS) is a key core capability in NASA’s Earth Science Data Systems Program. Designed and maintained by Raytheon Intelligence & Space, it is a comprehensive data and information system designed to perform a wide variety of functions in support of a heterogeneous national and international user community. EOSDIS provides a spectrum of services; some services are intended for a diverse group of casual users while others are intended only for a select cadre of research scientists chosen by NASA's peer-reviewed competitions, and then many fall somewhere in between. The primary services provided by EOSDIS are User Support, Data Archive, Management and Distribution, Information Management, and Product Generation, all of which are managed by thEarth Science Data and Information System (ESDIS) Project EOSDIS ingests, processes, archives, and distributes data from a large number of Earth-observing satellites, and provides end-to ...

Snow And Ice Distributed Active Archive Center
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or Sublimation (phase transition), sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes Nucleation, nucleate around particles in the atmosphere by attracting supercooling, supercooled water droplets, which Freezing, freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and Hard rime, rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cooperative Institute For Research In Environmental Sciences
The Cooperative Institute for Research in Environmental Sciences (CIRES) is a research institute that is sponsored jointly by the National Oceanic and Atmospheric Administration (NOAA) Office of Oceanic and Atmospheric Research (OAR) and the University of Colorado Boulder (CU). CIRES scientists study the Earth system, including the atmosphere, hydrosphere, cryosphere, biosphere, and geosphere, and communicate these findings to decision makers, the scientific community, and the public. It is one of 16 NOAA Cooperative Institutes (CIs). History and research CIRES was established in 1967 and is the oldest and largest of NOAA's cooperative institutes nationwide. CIRES facilitates interdisciplinary collaboration between researchers at the University of Colorado and NOAA's Office of Oceanic and Atmospheric Research (OAR), National Environmental Satellite, Data and Information Service (NESDIS), and the National Weather Service (NWS). CIRES includes more than 800 scientists, staff, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

World Data Center
The World Data Centre (WDC) system was created to archive and distribute data collected from the observational programmes of the 1957–1958 International Geophysical Year by the International Council of Science ( ICSU). The WDCs were funded and maintained by their host countries on behalf of the international science community. Originally established in the United States, Europe, Soviet Union, and Japan, the WDC system expanded to other countries and to new scientific disciplines. The WDC system included up to 52 Centres in 12 countries. All data held in WDCs were available for the cost of copying and sending the requested information. At the end of 2008, following the ICSU General Assembly in Maputo (Mozambique), the World Data Centres were reformed and a new ICSU World Data System In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glaciology
Glaciology (; ) is the scientific study of glaciers, or more generally ice and natural phenomena that involve ice. Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology, climatology, meteorology, hydrology, biology, and ecology. The impact of glaciers on people includes the fields of human geography and anthropology. The discoveries of water ice on the Moon, Mars, Europa and Pluto add an extraterrestrial component to the field, which is referred to as "astroglaciology". Overview A glacier is an extended mass of ice formed from snow falling and accumulating over a long period of time; glaciers move very slowly, either descending from high mountains, as in valley glaciers, or moving outward from centers of accumulation, as in continental glaciers. Areas of study within glaciology include glacial history and the reconstruction of past glaciation. A glaciologist is a person who studies glaciers. A glacial geologist ...

American Geographical Society
The American Geographical Society (AGS) is an organization of professional geographers, founded in 1851 in New York City. Most fellows of the society are Americans, but among them have always been a significant number of fellows from around the world. The society encourages activities that expands geographical knowledge, and the interpretation of that knowledge so that it can be useful to geographers and other disciplines, especially in a policymaking environment. It is the oldest nationwide geographical organization in the United States. Over the century and a half of its existence, the AGS has been especially interested in three regions: the Arctic, the Antarctic, and Latin America. A signature characteristic of the AGS-sponsored exploration was the requirement that its expeditions produce tangible scientific results. History The AGS was founded by 31 New Yorkers, who were wealthy philanthropists, historians, publishers and editors. Among them were George Folsom, Henry Grinnell ...
