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
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.
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.
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.
Citation of data and service
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.
This data set includes meteorological measurements from 32 climatological stations in Centre d'Etudes Nordiques, Quebec, Canada. The stations are in areas of frozen rock, permafrost mound, clayey mound, silty mound, tidal marsh, shore terrace, glacial till, permafrost plateau with snow patch, or under or near airport runways. Parameters include ground temperature, air temperature, relative humidity, and snow depth. Ground temperature was measured at 2 to 25 m below the surface at irregular intervals.
Information from snow pits and an ice core were collected at Dominion Range (location - 166 10' East, 85 15' South, elevation - 2,700m) in 1984-1985. The 6 meter snow pit was dug and sampled in 1984-1985 with a 3 cm sampling interval. Four 1 meter snow pits were dug and sampled in 1984-1985 with a 3 cm sampling interval. One core was drilled during the austral summer 1984-1985 with a depth of 160 meters.
Chemistry and density data were collected from the 1 meter pits. Chemistry, beta profile and density data were collected from the 6 meter snow pits. Chemistry (Na NH4, K, Mg, Ca, Cl, NO3, SO4, MSA), particles and a lead-210 profile were collected from the ice core.
The Geological Survey of Canada has maintained a network of permafrost thermal monitoring sites along the Norman Wells pipeline corridor between Norman Wells (NWT) and Zama, Alberta, since 1984. A total of 23 thermal fences or instrumented cross-sections have been established at which ground temperatures are measured both on and off the pipeline right-of-way (ROW). The design of the thermal fence allows an investigation of the effect of ROW clearing, pipeline trenching, installation and operation on the ground temperature and also to compare the thermal regime of the ROW and the surrounding terrain. Temperatures are measured to depths of 5 m close to the pipe and at a depth of 20 m between 4 and 10 m from the pipe and off-ROW. Initial manual data collection was at monthly to bi-monthly intervals decreasing to one to three times annually in later years. In the mid 1990s, a number of temperature cables were connected to dataloggers to provide high frequency measurements.
This Western United States snow reanalysis data set contains daily estimates of posterior snow water equivalent (SWE), fractional snow-covered area (fSCA) and snow depth (SD) at 16 arc-second (~500 m) resolution from water years 1985 to 2021. This data set was developed to be compared to SnowEx data sets but its utility reaches beyond that since its spatial and temporal bounds extend over the entire Western U.S. and over several decades.
ClimoBase is a collection of surface climate measurements collected in Northern Canada by Dr. Wayne Rouse between 1984 and 1998 in three locations: Churchill, Manitoba; Marantz Lake, Manitoba; and Inuvik, Northwest Territories. These data are comprised of surface-climate measurements, including solar time, wind speed, wind direction, dry-bulb, wet-bulb, and vapor pressure in 24 sites focused at the three Northern Canadian locations. The sites were chosen to include a variety of terrains in the study: sedge fen wetland, willow-birch wetland, lichen-heath, bedrock boulders/heath, spruce- tamarack forest, tundra lake, creek, various (e.g. a basin: sedge, willow, lichen-heath, forest, etc.), sparse vegetation (short grass/sedge, heath spp.), and coastal marsh (tall grass, sandy soils). The measurements were taken in increments ranging from seasonally to every 15 minutes. In all, 177 different variables were measured and recorded. The data are valuable due to their unique and consistent nature.
