Scientific Data

NESDIS provides timely access to global environmental data from satellites and other sources to promote, protect, & enhance the Nation's economy, security, environment, & quality of life. To fulfill its responsibilities, NESDIS acquires and manages the Nation's operational environmental satellites, provides data and information services, and conducts related research.

The Data Distribution Centre (DDC) of the Intergovernmental Panel on Climate Change (IPCC) has been established to facilitate the timely distribution of a consistent set of up-to-date scenarios of changes in climate and related environmental and socio-economic factors for use in climate impacts assessments. The intention is that these new assessments can feed into the review process of the IPCC.

GEOROC stands for the GEOchemistry of Rocks of the Oceans and Continents. GEOROC is part of EarthChem, a new consortium of geochemical databases consisting of PetDB, NAVDAT and GEOROC. EarthChem serves the international geochemical community with chemical and isotope data of igneous rocks and minerals, together with matadata about samples and analytical procedures. GEOROC currently covers igneous rocks from Convergent Margins, Oceanic Islands and Large Igneous Provinces. GEOROC is being compiled by the database team at the Max-Planck-Institut fr Chemie in Mainz, Germany.

The quantity and detail of geochemical data now available requires the assistance of modern information technology approaches in order to use the data in the most flexible, complete and effective way. This site contains links to three main databases: GEOROC, NAVDAT, and PETDB. GEOROC, NAVDAT and PetDB have produced relational databases that serve geochemical analyses of igneous rocks and minerals together with a wide array of metadata about the samples and the analytical procedure to the broad community of Earth scientists. Collaboration between the three independently developed database efforts has ensured that by sharing the basic data schema employed (Lehnert et al., G3, 2000) the data in the individual databases eventually can be seamlessly integrated through future developments in information management.

The Northern California Earthquake Data Center (NCEDC) is a joint project of the University of California Berkeley Seismological Laboratory (BSL) and the United States Geological Survey (USGS). The NCEDC is a long-term archive and distribution center for seismological and geodetic data for Northern and Central California and is partially supported by funding from the USGS component of the National Earthquake Hazards Reduction Program (NEHRP).

Lawrence Berkeley National Laboratory (LBNL), Lawrence Livermore National Laboratory (LLNL), Triangle Universities Nuclear Laboratory (TUNL), McMaster University, and the National Institute of Standards and Technology (NIST).

The National Center for Health Statistics' Web site is a rich source of information about Americas health. As the Nations principal health statistics agency, we compile statistical information to guide actions and policies to improve the health of our people. We are a unique public resource for health information-a critical element of public health and health policy. Working with partners throughout the health community, we use a variety of approaches to efficiently obtain information from the sources most able to provide information. We collect data from birth and death records, medical records, interview surveys, and through direct physical exams and laboratory testing. NCHS is a key element of our national public health infrastructure, providing important surveillance information that helps identify and address critical health problems. Here at NCHS, information is at the core of our mission and our Web site is a vital part of our effort to make this information work for you. Our site is designed to provide you with quick and easy access to the wide range of information and data available from us. We include an overview of our major data collection activities, present our data findings, and provide information about special activities and initiatives to improve access to--and the quality of--health statistics information. Our Web site has links to additional sources of health information and provides a way for you to query us electronically to obtain answers to your specific questions.

The Acoustic Monitoring Project of the VENTS Program began continuous monitoring of north Pacific Ocean seismicity in August 1991 using the U.S. Navy's SOund Surveillance System (SOSUS) In May, 1996, monitoring was extended to the eastern equatorial Pacific using moored autonomous hydrophones, with the North Atlantic added in March, 1999. The hydroacoustic method allows detection of low-magnitude seismicity and volcanic activity and provides more accurate source locations than land seismic networks. Hydrophone data from the North Eastern Pacific, Eastern Equatorial Pacific, and North Atlantic is available on this page.

Here you will find information about the seismic monitoring research work at the Lamont-Doherty Earth Observatory of Columbia University (LDEO). The main objectives of this web site are: 1) to facilitate research works at LDEO among the scientists, support staff and graduate students who are interested in issues related to the technical and scientific aspects of the verification of the Comprehensive Nuclear Test Ban Treaty (CTBT); 2) to disseminate data and information gathered by the staff at LDEO to the nuclear test verification research community as well as to the public. You can access information and data on this site. More information about the CTBT and nuclear tests can be found by navigating through other web sites using the links provided.

The physical climate as seen through a series of maps and analyses. The IRI Map Room offers many detailed analyses of current global and regional climate, as well as historical data. Many maps are linked directly to the IRI Data Library - for quick access to the data being viewed just click on the map. You will then be able to change dates, views, or even download the data. The map room is divided into 3 sections:Global - Current and past observations of the global physical climate including climatologies. Regional - Current and past observations of regional physical climate including climatologies. ENSO - Analyses for monitoring the current and past state of the El Nino Southern Oscillation (ENSO).

The International Research Institute for Climate Prediction/Lamont-Doherty Earth Observatory (IRI/LDEO) Climate Data Library contains over 300 datasets from a variety of earth science disciplines and climate-related topics.

STRONGMO is part of the NCEER Strong Ground Motion Facility's effort to develop a data base in which strong ground motion data is retrievable over a telecommunications line or a computer network. The tool is still in its experimental stages. Presently the user has the capability to interogate the NCEER Strong Motion Data Base and then retrieve selected strong motion data (both parametric and time-series) via kermit, a communications program developed at Columbia University. The tool also provides the user with the ability to: contact staff at Lamont-Doherty Earth Observatory via electronic mail; find out the latest status of the NCEER/Lamont Digital Strong-Motion Network; and retrieve raw data retrieved from the Network. The database consists of a comprehensive collection of earthquake, strong motion record, time-series, and recording site parameters. One of the most important features of the database is that it contains the actual time-histories on-line in a consistent format (the AH format developed at Lamont). The Data Base is in a relational format which allows for complex queries on the data. The data itself comes from two different sources; 20 digitally recording accelerographs operated by Lamont and NCEER and over 50 magnetic tapes that were purchased from several strong- motion data archiving agencies, including: the National Geophysical Data Center in Boulder, Colorado; California Division of Mines and Geology; and the United States Geological Survey in Menlo Park, California.

Monthly forecasts of tropical Pacific sea surface temperature (SST) and wind anomalies. Also serves as the homepage for the Climate Modeling and Diagnostics Group at Lamont-Doherty Earth Observatory.

SESAR, the Solid Earth SAmple Registry, is an NSF funded project to build a web-based digital registry where investigators, curators, or other persons collecting and managing solid earth samples can register these samples to obtain an International Geo Sample Number IGSN, a serial number that for the first time will allow samples to be uniquely identified on a global scale. Through use of the IGSN , it will become possible to link and integrate wide ranges of sample-based data types, leading to new interdisciplinary approaches in research.
