In February 1986 the NIST measurements were communicated to appropriate astronomers for use in ground-based testing and calibration programs for the GHRS, and in 1990 the NIST group published the new wavelengths for about 3000 lines in the Supplement Series of the Astrophysical Journal. The full report on the NIST measurements in the form of a complete and detailed atlas of the platinum/neon spectrum presented in this special issue of the Journal of Research of NIST will be highly useful to a wide range of scientists.
The AERONET (AErosol RObotic NETwork) program is a federation of ground-based remote sensing aerosol networks established by NASA and PHOTONS (PHOtométrie pour le Traitement Opérationnel de Normalisation Satellitaire; Univ. of Lille 1, CNES, and CNRS-INSU) and is greatly expanded by networks (e.g., RIMA, AeroSpan, AEROCAN, and CARSNET) and collaborators from national agencies, institutes, universities, individual scientists, and partners. The program provides a long-term, continuous and readily accessible public domain database of aerosol optical, microphysical and radiative properties for aerosol research and characterization, validation of satellite retrievals, and synergism with other databases. The network imposes standardization of instruments, calibration, processing and distribution.
>>>!!!<<<The IGETS data base at GFZ Potsdam continues the activities of the International Center for Earth Tides (ICET), in particular, in collecting, archiving and distributing Earth tide records from long series of gravimeters, tiltmeters, strainmeters and other geodynamic sensors. >>>!!!<<< The ICET Data Bank contains results from 360 tidal gravity stations: hourly values, main tidal waves obtained by least squares analyses, residual vectors, oceanic attraction and loading vectors. The Data Bank contains also data from tiltmeters and extensometers. ICET is responsible for the Information System and Data Center of the Global Geodynamic Project (GGP). The tasks ascribed to ICET are : to collect all available measurements of Earth tides (which is its task as World Data Centre C), to evaluate these data by convenient methods of analysis in order to reduce the very large amount of measurements to a limited number of parameters which should contain all the desired and needed geophysical information, to compare the data from different instruments and different stations distributed all over the world, evaluate their precision and accuracy from the point of view of internal errors as well as external errors, to help to solve the basic problem of calibrations and to organize reference stations or build reference calibration devices, to fill gaps in information or data as far as feasible, to build a data bank allowing immediate and easy comparison of Earth tide parameters with different Earth models and other geodetical and geophysical parameters like geographical position, Bouguer anomaly, crustal thickness and age, heat flow, ... to ensure a broad diffusion of the results and information to all interested laboratories and individual scientists.
The Infrared Space Observatory (ISO) is designed to provide detailed infrared properties of selected Galactic and extragalactic sources. The sensitivity of the telescopic system is about one thousand times superior to that of the Infrared Astronomical Satellite (IRAS), since the ISO telescope enables integration of infrared flux from a source for several hours. Density waves in the interstellar medium, its role in star formation, the giant planets, asteroids, and comets of the solar system are among the objects of investigation. ISO was operated as an observatory with the majority of its observing time being distributed to the general astronomical community. One of the consequences of this is that the data set is not homogeneous, as would be expected from a survey. The observational data underwent sophisticated data processing, including validation and accuracy analysis. In total, the ISO Data Archive contains about 30,000 standard observations, 120,000 parallel, serendipity and calibration observations and 17,000 engineering measurements. In addition to the observational data products, the archive also contains satellite data, documentation, data of historic aspects and externally derived products, for a total of more than 400 GBytes stored on magnetic disks. The ISO Data Archive is constantly being improved both in contents and functionality throughout the Active Archive Phase, ending in December 2006.

The CMU Multi-Modal Activity Database (CMU-MMAC) database contains multimodal measures of the human activity of subjects performing the tasks involved in cooking and food preparation. The CMU-MMAC database was collected in Carnegie Mellon's Motion Capture Lab. A kitchen was built and to date twenty-five subjects have been recorded cooking five different recipes: brownies, pizza, sandwich, salad, and scrambled eggs.
Remote Sensing Systems is a world leader in processing and analyzing microwave data from satellite microwave sensors. We specialize in algorithm development, instrument calibration, ocean product development, and product validation. We have worked with more than 30 satellite microwave radiometer, sounder, and scatterometer instruments over the past 40 years. Currently, we operationally produce satellite retrievals for SSMIS, AMSR2, WindSat, and ASCAT. The geophysical retrievals obtained from these sensors are made available in near-real-time (NRT) to the global scientific community and general public via FTP and this web site.
The ASTER Project consists of two parts, each having a Japanese and a U.S. component. Mission operations are split between Japan Space Systems (J-spacesystems) and the Jet Propulsion Laboratory (JPL) in the U.S. J-spacesystems oversees monitoring instrument performance and health, developing the daily schedule command sequence, processing Level 0 data to Level 1, and providing higher level data processing, archiving, and distribution. The JPL ASTER project provides scheduling support for U.S. investigators, calibration and validation of the instrument and data products, coordinating the U.S. Science Team, and maintaining the science algorithms. The joint Japan/U.S. ASTER Science Team has about 40 scientists and researchers. Data access via NASA Reverb, ASTER Japan site, earth explorer, GloVis,GDEx and LP DAAC. See here . In Addition data are availabe through the newly implemented ASTER Volcano archive (AVA) .
The European VLBI Network (EVN) is an interferometric array of radio telescopes located primarily in Europe and Asia, with additional telescopes in South Africa and Puerto Rico. The EVN performs high-resolution observations of cosmic radio sources at wavelenghts from 92cm to 7mm. The EVN Data Archive contains, among other things, the correlated data from EVN observations plus pipeline output, including the initial calibration tables to apply to the correlated data and preliminary images. In general, the correlated data and some pipeline results are proprietary for one year following distribution to the PI of the final epoch of observations resulting from a proposal after which the data enters the public domain; more details are in the "EVN Data Access Policy" linked via the archive-introduction page.
Geochron is a global database that hosts geochronologic and thermochronologic information from detrital minerals. Information included with each sample consists of a table with the essential isotopic information and ages, a table with basic geologic metadata (e.g., location, collector, publication, etc.), a Pb/U Concordia diagram, and a relative age probability diagram. This information can be accessed and viewed with any web browser, and depending on the level of access desired, can be designated as either private or public. Loading information into Geochron requires the use of U-Pb_Redux, a Java-based program that also provides enhanced capabilities for data reduction, plotting, and analysis. Instructions are provided for three different levels of interaction with Geochron: 1. Accessing samples that are already in the Geochron database. 2. Preparation of information for new samples, and then transfer to Arizona LaserChron Center personnel for uploading to Geochron. 3. Preparation of information and uploading to Geochron using U-Pb_Redux.
SeaBASS, the publicly shared archive of in situ oceanographic and atmospheric data maintained by the NASA Ocean Biology Processing Group (OBPG). High quality in situ measurements are prerequisite for satellite data product validation, algorithm development, and many climate-related inquiries. As such, the NASA Ocean Biology Processing Group (OBPG) maintains a local repository of in situ oceanographic and atmospheric data to support their regular scientific analyses. The SeaWiFS Project originally developed this system, SeaBASS, to catalog radiometric and phytoplankton pigment data used their calibration and validation activities. To facilitate the assembly of a global data set, SeaBASS was expanded with oceanographic and atmospheric data collected by participants in the SIMBIOS Program, under NASA Research Announcements NRA-96 and NRA-99, which has aided considerably in minimizing spatial bias and maximizing data acquisition rates. Archived data include measurements of apparent and inherent optical properties, phytoplankton pigment concentrations, and other related oceanographic and atmospheric data, such as water temperature, salinity, stimulated fluorescence, and aerosol optical thickness. Data are collected using a number of different instrument packages, such as profilers, buoys, and hand-held instruments, and manufacturers on a variety of platforms, including ships and moorings.
TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) is the first bistatic SAR mission in space. TanDEM-X and its twin satellite TerraSAR-X are flying in a closely controlled formation with typical distances between 250 and 500 meters. Primary mission objective is the generation of a consistent global digital elevation model with few meter level height accuracy. Beyond that, GFZ equipped TanDEM-X with a geodetic grade GPS receiver for precise baseline determination and for radio occultation measurements. TanDEM-X was launched on June 21, 2010 for a 5 year mission lifetime. The GPS radio occultation data of the German TanDEM-X satellite are analysed and globally distributed vertical atmospheric profiles (bending angles, refractivity, temperature, water vapor) are derived and provided for the international user community.
The International Ocean Discovery Program (IODP) is an international marine research collaboration that explores Earth's history and dynamics using ocean-going research platforms to recover data recorded in seafloor sediments and rocks and to monitor subseafloor environments. IODP depends on facilities funded by three platform providers with financial contributions from five additional partner agencies. Together, these entities represent 26 nations whose scientists are selected to staff IODP research expeditions conducted throughout the world's oceans. IODP expeditions are developed from hypothesis-driven science proposals aligned with the program's science plan Illuminating Earth's Past, Present, and Future. The science plan identifies 14 challenge questions in the four areas of climate change, deep life, planetary dynamics, and geohazards. Until 2013 under the name: International Ocean Drilling Program.
