Geophys. and ground (snow, rain, sea state, etc.) Nifty 11,178.40-122.05. This is the most recent version of these data. Figure 3 displays these regions. All data are available via FTP. In the 1980s, a Sea Ice Grid (SIGRID) format was developed (Thomson 1981) and adopted as a World Meteorological Organization (WMO) standard shortly thereafter. The ice charts have information on ice concentration, stage of development, and ice form, following World Meteorological Organization terminology. For example, a chart dated 16 October 2006 may contain data from the previous three days, as noted in each metadata file. Most relevant lists of abbreviations for CIS (Canadian Ice Service) “We’re ahead of the game,” Langis said of the early retreat of ice in Frobisher Bay. They create coverages and then convert the coverages to shapefiles with corresponding metadata. There are potential errors introduced with the manual assimilation process. The data files in this data set are available via FTP. The Canadian Ice Service (CIS) produces digital Arctic regional sea ice charts for marine navigation, climate research, and input to the Global Digital Sea Ice Data Bank (GDSIDB). This format has evolved over time with the latest version, which is now a vector format, called SIGRID-3 (IOC 2004). May 2018: A. Windnagel updated Figure 2 to describe the change in format for data starting 30 May 2018.  Each metadata (.xml) file lists the sources used.

The Canadian Ice Service maps fast ice weekly via satellite-image analysis to prepare regional ice charts (Environment Canada, 2013), on which fast ice is uniquely coded as 10/10 ice concentration. This was a modified version of the 1:1,000,000 scale data set from World Vector Shoreline Plus (WVS+), 3rd Edition, 2004. Expedition to a Crumbling Ice Shelf. When scientists talk about the cryosphere, they mean the places on Earth where water is in its solid form, frozen into ice or snow.

Within each year is the tar file that contains the shapefile and the associated metadata file. However, the metadata files state the following: "The reliability and accuracy of the data set is directly related to the availability, resolution and the effects of atmospheric (cloud, daylight, etc.) The CIS uses the operational Ice Service Integrated System (ISIS) to create the regional ice charts based on MANICE procedures (Environment Canada 2005). For a more complete history of the egg code and ice chart digitization, including a summary of the SIGRID-3 format, see the History of Ice Chart Digitization section of the National Ice Center Arctic Sea Ice Charts and Climatologies in Gridded Format documentation and the material at the Global Digital Sea Ice Data Bank site.Â. Refer to Figure 5. Each set of files is combined into a tar file (.tar) for distribution. Res. 116: C03007, doi:10.1029/2009JC005855. This method worked well, but then the digital era emerged and operational centers shifted their focus from paper charts to digital ice charts and used GIS techniques to process data and produce ice charts. The start date of the data for each region differs. BROWSE BY COUNTRY. Canadian Ice Service News and Updates from The Economictimes.com. Made entirely of snow and ice, this architectural marvel is a wonder to behold. Air Quality Science and Research, ECCC . Categories. The ice services of the International Ice Chart Working Group may also have collections. Nili offers Canadian hosted Business email, website and domain. The CIS followed the SIGRID-3 (IOC 2004) instructions for decoding sea ice, but made a few modifications to the SIGRID-3 metadata files (.xml). Innovation, Science and Economic Development Canada (ISED) works with Canadians in all areas of the economy and in all parts of the country to improve conditions for investment, enhance Canada's innovation performance, increase Canada's share of global trade and build a fair, efficient and competitive marketplace.We are the federal institution that leads the Innovation, Science and … See About the Cryosphere. The egg code, termed this way because of its shape, was a way to map the ice characteristics such as total ice concentration, partial concentrations, stage of development, and form of ice on a paper map. On Thin Ice: Originally, operational data centers denoted ice characteristics by grouping the ice with similar characteristics into polygons. Connect with the latest marine alerts coming from the Authoritative Source of Weather Alerts 24/7; Environment Canada.

The CIS takes input from various sources such as satellites, aerial reconnaissance, and ship reports based on data availability. “The Canadian Ice Service, an arm of Environment Canada, said there is 10 per cent more ice this year compared to the 30-year average. 23, WMO/TD-No. NSIDC Special Report 9. NSIDC renames the projection file to correspond to the shapefile file name in each tar file. The underlying reference frame for the data is the World Geodetic System of 1984 (WGS84) using the updated WGS Earth ellipsoid (2004) (CIS 2006). Boulder, Colorado USA: National Snow and Ice Data Center. Users can look at MANICE (Environment Canada 2005) for more information. The time stamp is GMT and corresponds to the time that the file was created. Review CIS 2006 for a complete description of the differences between the CIS SIGRID-3 format and the official SIGRID-3 format (IOC 2004). What's hot in the news around climate and sea ice and what are scientists talking about now? The Canadian Ice Service (CIS) produces digital Arctic regional sea ice charts for marine navigation, climate research, and input to the Global Digital Sea Ice Data Bank (GDSIDB). This section contains some sample data records including a sample of two SIGRID-3 shapefiles: One for the Great Lakes Region (Figure 6) and one for the Hudson Bay Region (Figure 7). July 2010: A.

Each ice chart contains up to 72 hours of input data. The U.S. National Ice Center, in cooperation with the Canadian Ice Service under the North American Ice Service Agreement, has begun producing ice charts, support files, and a seasonal outlook. This data set covers the Canadian Arctic regions including Northern Canadian waters (Western Arctic, Eastern Arctic, and Hudson Bay) and Southern Canadian waters (Great Lakes and East Coast). The shapefiles and their associated metadata files are named according to the following convention and as described in Table 2: Note: In some cases, the original files needed to be replaced with newer files. The DCW and the WVS+ data set contains vector data which has been customized at CIS to correct gross errors, particularly in the Canadian Arctic and Greenland. Users should note that this list of sources is comprehensive and lists all possible data sources, not just the data sources that directly relate to that shapefile. Subscribe below and stay informed. The metadata files for the various regions are very similar. The operational data centers needed a way to incorporate the information from the paper charts to a digital format. Intergovernmental Oceanographic Commission of UNESCO. That’s closer than usual, and it’s not as extensive, confirmed Gilles Langis, a senior ice forecaster with the Canadian Ice Service. The Manual of Standard Procedures for Observing and Reporting Ice Conditions (MANICE) is the authoritative guide produced by the CIS that explains how sea ice charts are produced (Environment Canada 2005). The parameters include total ice concentration, partial concentration, stage of development, and ice form. FTP data can be downloaded through a Web browser or command line via FTP. Sea ice thickness can be assessed using stage of development as a proxy for thickness (NIC 2006). Benchmarks .
