The Data Access Portal has information in 3 columns. An outline of the content in these columns is provided above. When first entering the search interface, all potential datasets are listed. Datasets are indicated in the map and results tabulation elements which are located in the middle column. The order of results can be modified using the "Sort by" option in the left column. On top of this column is normally relevant guidance information to user presented as collapsible elements.

If the user want to refine the search, this can be done by constraining the bounding box search. This is done in the map - the listing of datasets is automatically updated. Date constraints can be added in the left column. For these to take effect, the user has to push the button marked search. In the left column it is also possible to specific text elements to search for in the datasets. Again pushing the button marked "Search" is necessary for these to take action. Complex search patterns can be constructed using logical operators and phrases embedded in quotation marks. Logical operators include AND, OR and NOT. Remember to add space around operators. Text strings that are not quoted are trated as separate words and will match any of the words (i.e. assuming the OR operator). E.g. in order to find WMO synoptic weather station data from Verlegenhuken use the search phrase: [synop AND verlegenhuken]. Searches are case insensitive.

Other elements indicated in the left and right columns are facet searches, i.e. these are keywords that are found in the datasets and all datasets that contain these specific keywords in the appropriate metadata elements are listed together. Further refinement can be done using full text, date or bounding box constraints. Individuals, organisations and data centres involved in generating or curating the datasets are listed in the facets in the right column.

Collections allows the user to search in subsets of the existing catalogue. The collections are primarily data management projects that have been incorporated in the ADC catalogue after the project has ended. In this context the ADC is the long term access solution for these data. The collections currently served through ADC include (datasets may belong to multiple data collections):

ADC is the full collection of this service CC is the CryoClim collection

In order to search a specific data collection select that collection. If no data collection is selected all collections are searched.

• GCW is the collection for the WMO Global Cryosphere Watch and are better explored through https://gcw.met.no/.
• NMAP is the NORMAP e-infrastructure collection and are better explored through https://www.nordatanet.no/.
• NSDN is the data collection for the Norwegian Scientific Data Network and are better explored through https://www.nordatanet.no/.
• SIOS is the data collection for the Svalbard Integrated Arctic Earth Observing System.
  • SIOSIN, InfraNOR, SESS_* and SIOSAP are also related to this and all are better explored through the link provided above.
• YOPP is the data collection used to serve the Year of Polar Prediction and are better explored through https://yopp.met.no/.
• CC are data related to the CryoClim project.
• AeN are data related to the Nansen Legacy project and are better explored through the SIOS Data Access Point using the collection defined there which is available through this URL.
• NMDC are MET contributions to the Norwegian Marine Data Centre

Some data collections are currently in the process of being added to the system. This includes:

• DOKI is the data collection for the Norwegian contributions to the International Polar Year.
  • This is currently being cleaned for reimplementation.
• DAMOC is the data collection for the EU FP6 project DAMOCLES
  • This is currently being cleaned for reimplementation.
• ACCESS is the data collection for the EU FP7 project ACCESS
  • This is currently being cleaned for reimplementation.
• APPL is the data collection for the EU H2020 project APPLICATE
• AP is the data collection for the EU H2020 project Arctic Passion
  • This is in the process of being populated.
• CVL is a collection for the ESA Cryosphere Virtual Laboratory and is better explored through that service.
• SIOS, InfraNOR, SIOSCD, SIOSAP, SESS_* are collections related to SIOS. These are better explored through the SIOS Data Access Portal
  • Some cleaning is pending between InfraNOR and SIOSIN, for some of the SESS collections.

Always remember to cite data when used!

Citation information for individual datasets is often provided in the metadata. However, not all datasets have this information embedded in the discovery metadata. On a general basis a citation of a dataset include the same components as any other citation:

•         author,
•         title,
•         year of publication,
•         publisher (for data this is often the archive where it is housed),
•         edition or version,
•         access information (a URL or persistent identifier, e.g. DOI if provided)

The information required to properly cite a dataset is normally provided in the discovery metadata the datasets.

If you use data retrieved through this portal, please acknowledge the Norwegian Meteorological Institute/Arctic Data Centre.
