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 National Science Foundation (NSF) Ultraviolet (UV) Monitoring Network provides data on ozone depletion and the associated effects on terrestrial and marine systems. Data are collected from 7 sites in Antarctica, Argentina, United States, and Greenland. The network is providing data to researchers studying the effects of ozone depletion on terrestrial and marine biological systems. Network data is also used for the validation of satellite observations and for the verification of models describing the transfer of radiation through the atmosphere.
The twin GRACE satellites were launched on March 17, 2002. Since that time, the GRACE Science Data System (SDS) has produced and distributed estimates of the Earth gravity field on an ongoing basis. These estimates, in conjunction with other data and models, have provided observations of terrestrial water storage changes, ice-mass variations, ocean bottom pressure changes and sea-level variations. This portal, together with PODAAC, is responsible for the distribution of the data and documentation for the GRACE project.

The term GNSS (Global Navigation Satellite Systems) comprises the different navigation satellite systems like GPS, GLONAS and the future Galileo as well as rawdata from GNSS microwave receivers and processed or derived higher level products and required auxiliary data. The results of the GZF GNSS technology based projects are used as contribution for maintaining and studying the Earth rotational behavior and the global terrestial reference frame, for studying neotectonic processes along plate boundaries and the interior of plates and as input to short term weather forecasting and atmosphere/climate research. Currently only selected products like observation data, navigation data (ephemeriden), meteorological data as well as quality data with a limited spatial coverage are provided by the GNSS ISDC.
ETH Data Archive is ETH Zurich's long-term preservation solution for digital information such as research data, digitised content, archival records, or images. It serves as the backbone of data curation and for most of its content, it is a “dark archive” without public access. In this capacity, the ETH Data Archive also archives the content of ETH Zurich’s Research Collection which is the primary repository for members of the university and the first point of contact for publication of data at ETH Zurich. All data that was produced in the context of research at the ETH Zurich, can be published and archived in the Research Collection. An automated connection to the ETH Data Archive in the background ensures the medium to long-term preservation of all publications and research data. Direct access to the ETH Data Archive is intended only for customers who need to deposit software source code within the framework of ETH transfer Software Registration. Open Source code packages and other content from legacy workflows can be accessed via ETH Library @ swisscovery (https://library.ethz.ch/en/).
The main function of the GGSP (Galileo Geodetic Service Provider) is to provide a terrestrial reference frame, in the broadest sense of the word, to both the Galileo Core System (GCS) as well as to the Galileo User Segment (all Galileo users). This implies that the GGSP should enable all users of the Galileo System, including the most demanding ones, to access and realise the GTRF with the precision required for their specific application. Furthermore, the GGSP must ensure the proper interfaces to all users of the GTRF, especially the geodetic and scientific user groups. In addition the GGSP must ensure the adherence to the defined standards of all its products. Last but not least the GGSP will play a key role to create awareness of the GTRF and educate users in the usage and realisation of the GTRF.

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.

GGOS is the Global Geodetic Observing System of the International Association of Geodesy (IAG). It provides observations of the three fundamental geodetic observables and their variations, that is, the Earth's shape, the Earth's gravity field and the Earth's rotational motion. GGOS integrates different geodetic techniques, different models, different approaches in order to ensure a long-term, precise monitoring of the geodetic observables in agreement with the Integrated Global Observing Strategy (IGOS). GGOS provides the observational basis to maintain a stable, accurate and global reference frame and in this function is crucial for all Earth observation and many practical applications.

<<<!!!<<< ----This page has been archived on the Web--- >>>!!!>>> Environment and Climate Change Canada collects biological samples from a number of lakes and rivers across Canada in support of federally mandated programs. Environment and Climate Change Canada has collected fish and invertebrates from the Great Lakes since 1977 in support of the Great Lakes Water Quality Agreement (GLWQA). More recently, samples have been collected nationally to support Canada's Chemicals Management Plan and the Clean Air Regulatory Agenda. Environment and Climate Change Canada also maintains a specimen bank of frozen tissues which is a requirement of the GLWQA and is an integral part of departmental monitoring and research programs. The National Aquatic Biological Specimen Bank (NABSB) is located in a dedicated facility at the Canada Centre for Inland Waters in Burlington, Ontario. The NABSB holds more than 37,000 samples of fish and invertebrates collected over the last 30+ years of environmental monitoring in Canada. Research conducted using samples from the NABSB has produced more than 60 scientific publications, reports and book chapters
