Historical Climate Data Canada

Données climatiques historiques

Subject(s)
Content type(s)
Country
Historical Climate Data (formerly: The National Climate Data and Information Archive - NCDC) is a web-based resource maintained by Environment and Climate Change Canada and the Meteorological Service of Canada. The site houses a number of statistical and data compilation and viewing tools. From the website, users can access historical climate data for Canadian locations and dates, view climate normals and averages, and climate summaries. A list of Canadian air stations and their meteorological reports and activities is also available, along with rainfall statistics for more than 500 locations across Canada. Users can also download the Canadian daily climate data for 2006/07. In addition, technical documentation is offered for data users to interpret the available data. Other documentation includes a catalogue of Canadian weather reporting stations, a glossary, and a calculation of the 1971 to 2000 climate normals for Canada. This resource carries authority and accuracy because it is maintained by a national government department and service. While the majority of the statistics are historical, the data is up-to-date and contains current and fairly recent climate data. This government resource is intended for an audience that has the ability and knowledge to interpret climatological data

WHOI Argo Program

Woods Hole Oceanographic Institution Argo Program

Subject(s)
Content type(s)
Country
The Argo observational network consists of a fleet of 3000+ profiling autonomous floats deployed by about a dozen teams worldwide. WHOI has built about 10% of the global fleet. The mission lifetime of each float is about 4 years. During a typical mission, each float reports a profile of the upper ocean every 10 days. The sensors onboard record fundamental physical properties of the ocean: temperature and conductivity (a measure of salinity) as a function of pressure. The depth range of the observed profile depends on the local stratification and the float's mechanical ability to adjust it's buoyancy. The majority of Argo floats report profiles between 1-2 km depth. At each surfacing, measurements of temperature and salinity are relayed back to shore via satellite. Telemetry is usually received every 10 days, but floats at high-latitudes which are iced-over accumulate their data and transmit the entire record the next time satellite contact is established. With current battery technology, the best performing floats last 6+ years and record over 200 profiles.

Italian Centre for Astronomical Archive

IA2

Subject(s)
Content type(s)
Country
The long-term goal of this project is to implement a new strategy for preserving and providing access to the Astrophysical data heritage. IA2 is an ambitious Italian Astrophysical research infrastructure project that aims at co-ordinating different national initiatives to improve the quality of astrophysical data services. It aims at co-ordinating these developments and facilitating access to this data for research purposes. The first working target, is the implementation of the TNG Long-Term Archive (LTA). Its feasibility was demonstrated by the LTA pilot project prototype, funded by CNAA in 2001 and completed successfully in July 2002. The implementation of the TNG archive implies: − interfacing with the Centro "Galileo Galilei" (CGG) for the acquisition of TNG data; − long-term storage of scientific, technical and auxiliary data from the TNG; − providing accessibility by the CGG staff and by the scientific community to original and derived data; − providing tools to support the life cycle of observing proposals. The second target of the proposal aims at ensuring harmonization with other projects related to archiving of data of astrophysical interest, with particular reference to projects involving the Italian astronomical community (LBT, VST, GSC-II, DPOSS, …), to the Italian Solar and Solar System Physics community (SOLAR, SOLRA, ARTHEMIS which form SOLARNET – a future node of EGSO) and to the national and international coordination efforts fostering the idea of a multiwavelength Virtual Astronomical Observatory, and the use of the archived data through the Italian Astronomical Grid.

World Glacier Monitoring Service

WGMS

Subject(s)
Content type(s)
Country
The World Glacier Monitoring Service (WGMS) collects standardized observations on changes in mass, volume, area and length of glaciers with time (glacier fluctuations), as well as statistical information on the distribution of perennial surface ice in space (glacier inventories). Such glacier fluctuation and inventory data are high priority key variables in climate system monitoring; they form a basis for hydrological modelling with respect to possible effects of atmospheric warming, and provide fundamental information in glaciology, glacial geomorphology and quaternary geology. The highest information density is found for the Alps and Scandinavia, where long and uninterrupted records are available. As a contribution to the Global Terrestrial/Climate Observing System (GTOS, GCOS), the Division of Early Warning and Assessment and the Global Environment Outlook of UNEP, and the International Hydrological Programme of UNESCO, the WGMS collects and publishes worldwide standardized glacier data.
