The Chesapeake Bay Environmental Observatory (CBEO) is a prototype to demonstrate the utility of newly developed Cyberinfrastructure (CI) components for transforming environmental research, education, and management. The CBEO project uses a specific problem of water quality (hypoxia) as means of directly involving users and demonstrating the prototype’s utility. Data from the Test Bed are being brought into a CBEO Portal on a National Geoinformatics Grid developed by the NSF funded GEON. This is a cyberinfrastructure netwrok that allows users access to datasets as well as the tools with which to analyze the data. Currently, Test Bed data avaialble on the CBEO Portal includes Water Quality Model output and water quality monitorig data from the Chesapeake Bay Program's CIMS database. This data is also available as aggregated "data cubes". Avaialble tools include the Data Access System for Hydrology (DASH), Hydroseek and an online R-based interpolator.

The National Pollutant Release Inventory (NPRI) is Canada's legislated, publicly accessible inventory of pollutant releases (to air, water and land), disposals and transfers for recycling. It is a key resource for: identifying pollution prevention priorities; supporting the assessment and risk management of chemicals, and air quality modelling; helping develop targeted regulations for reducing releases of toxic substances and air pollutants; encouraging actions to reduce the release of pollutants into the environment; and improving public understanding. The NPRI comprises: Information reported by facilities and published by Environment and Climate Change Canada under the authority of Sections 46 – 50 of the Canadian Environmental Protection Act, 1999 (CEPA 1999); and Comprehensive emission summaries and trends for key air pollutants, based on facility-reported data and emission estimates for other sources such as motor vehicles, residential heating, forest fires and agriculture. For the latest reporting year, 7,708 facilities reported to the NPRI on more than 300 listed substances. Comprehensive air pollutant emission summaries and trends were compiled by Environment and Climate Change Canada for criteria air contaminants (the main pollutants contributing to smog, acid rain and/or poor air quality), selected heavy metals and persistent organic pollutants.

CHAMP (CHAllenging Minisatellite Payload) is a German small satellite mission for geoscientific and atmospheric research and applications, managed by GFZ. With its highly precise, multifunctional and complementary payload elements (magnetometer, accelerometer, star sensor, GPS receiver, laser retro reflector, ion drift meter) and its orbit characteristics (near polar, low altitude, long duration) CHAMP will generate for the first time simultaneously highly precise gravity and magnetic field measurements over a 5 years period. This will allow to detect besides the spatial variations of both fields also their variability with time. The CHAMP mission had opened a new era in geopotential research and had become a significant contributor to the Decade of Geopotentials. In addition with the radio occultation measurements onboard the spacecraft and the infrastructure developed on ground, CHAMP had become a pilot mission for the pre-operational use of space-borne GPS observations for atmospheric and ionospheric research and applications in weather prediction and space weather monitoring. End of the mission of CHAMP was at September 19 2010, after ten years, two month and four days, after 58277 orbits.
<<<!!!<<< The data is in the phase of migration to another system. Therefore the repository is no longer available. This record is out-dated.; 2020-10-06 !!! >>>!!!>>> Due to the changes at the individual IGS analysis centers during these years the resulting time series of global geodetic parameters are inhomogeneous and inconsistent. A geophysical interpretation of these long series and the realization of a high-accuracy global reference frame are therefore difficult and questionable. The GPS reprocessing project GPS-PDR (Potsdam Dresden Reprocessing), initiated by TU München and TU Dresden and continued by GFZ Potsdam and TU Dresden, provides selected products of a homogeneously reprocessed global GPS network such as GPS satellite orbits and Earth rotation parameters.
