The core partner data centres that are integrated in NorDataNet are listed in https://www.nordatanet.no/en/node/69. In addition to this NorDataNet harvests information on relevant datasets from a number of other data centres. The data centre responsible for the data presented is usually (but not always) listed in the discovery metadata. In essence NorDataNet is an aggregating service that combines information from a number of existing data centres.
Citation of data and service
If you use data retrieved through this portal, please acknowledge our funding source:
Research Council of Norway, project number 245967/F50, Norwegian Scientific Data Network.
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)
All partner repositories of NorDataNet support Digital Object Identifiers (DOI), but not all datasets are minted. Whether or not minted depends often on source of the data (e.g. operational data are often yet not minted). However, all data centres support persistent identifiers according to local systems. The information required to properly cite a dataset is normally provided in the discovery metadata the datasets.
Brief user guide
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 identified in the drop down menu with and phrases embedded in quotation marks. Prefixing a phrase with '-' negates the phrase (i.e. should not occur in the results). 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. The combination of search fields (including facets) is based on a logical "AND" combination of the fields, i.e. all conditions are fulfilled for the results provided.
Data for this study were collected from the Little River Watershed (LRW) Micronet regional study areas of southeastern Georgia, US using in situ soil moisture sensors at depths of 2, 8, and 12 inches in addition to tipping bucket rain gauges as part of the Soil Moisture Experiment 2003 (SMEX03).
This data set includes data collected over the Soil Moisture Experiment 2003 (SMEX03) areas of Alabama, Georgia, and Oklahoma, USA, and Brazil. The SeaWinds scatterometer on NASA's Quick Scatterometer (QuikSCAT) satellite collected backscatter data.
This data set provides brightness temperature data acquired during the Soil Moisture Experiment 2003 (SMEX03) by the Special Sensor Microwave/Imager (SSM/I) conducted in the SMEX03 Oklahoma, the Alabama/Georgia, and Brazil study areas.

This dataset includes Geophysical Institute (GFI), University of Bergen mooring SV_200304 data. The mooring consists of 2 inst. (instrument type:instrument number(instrument depth)):RCM7:6196(2m) RCM7:8003(30m) . Metadata and raw/processed time series are presented as NetCDF, text and pdf(plots with statistics, calibration sheets, mooring drawing) files.
This archive presents the results of sea ice extent observations in Kongsfjorden - the Arctic fjord located in the west coast of Spitsbergen, Svalbard archipelago at approximately 79° N, 12° E . The permanent presence of Norwegian Polar Institute’s staff at Ny-Ålesund Research Station, and daily visits to the observatory on the mountain Zeppelinfjellet (474ma.s.l., south of Ny-Ålesund) enable regular visual sea ice observations in the fjord, which have been done systematically since 2003 . The observations are weather- and visibility permitting and typically conducted several times a week from February to June: from the onset of daylight conditions sufficient for visual observations and lasting until the end of ice season in the fjord. The archive covers years 2003 – 2021 and contains 668 ice charts evenly distributed over the period, on average 36 per ice season. Since some of the charts represented a few days of observations in a row, reporting “similar ice conditions”, the digitized archive comprises 887 ice observation days in total. This dataset is a detailed extension of previously published monthly values for sea ice extent in the inner part of Kongsfjorden, Svalbard 2003-2019, compiling in one archive the original observations of sea ice conditions in the fjord back to 2003.
