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 the search selector (identifying AND or OR behaviour). Words that should be included in the results can be identified by prefixing them with '+', similarily words that should not be found in the results should be prefixed with '-'. Text strings that are not quoted are treated as separate words and will match any of the words (i.e. assuming OR operator).
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. Utilisation of multiple elements in the search page are inclusive in the sense that all constraints are applied simultaneously. The search can be reset using the RESET buttons below the free text field or in the map. Following a reset it is wise to select parents in the search interface again to avoid having too many responses.
Merged model Data Files (MMDFs) were produced by the SLAV model for both SOP1 and SOP2 containing 7-day forecasts starting at 00 UTC. The output is available for 4 horizontal grid points surrounding selected observatories, every 15 minutes (i.e. every fourth timestep). Depending on variable, the output is instantaneous or a 15-min averaged value.

To clarify the mass and heat balance, snow depositional condition on ice sheet, AWS was installed at H128. The H128 Automatic Weather Station (AWS) Data Graph provides a variety of real-time data, including air temperature, relative humidity, wind speed, wind direction, up and down shortwave radiation, up and down longwave radiation, surface air pressure, snow height, snow temperature, and more. The H128 site is located on coastal Dronning Maud Land, East Antarctica (69.4S, 41.57E, 1380 m a.s.l). This AWS is maintained and operated by JARE/NIPR.
Zooplankton samples were collected by vertical haul of Quad-NORPAC nets at 58 stations in the Pacific sector of the Arctic Ocean. The Quad-NORPAC net (mesh sizes: 335, 150 and two of 63 micrometre [one is for a fixed sample and the other has a large-sized cod-end to collected fresh samples for incubation], mouth diameter: 45 cm) was towed between the surface and the depth of 150 m (or the bottom - 10 m at stations where the bottom was <150 m) at all stations.

Abstract:
These automatic weather station (AWS) data were measured as part of the "Snow Impurity and Glacial Microbe effects on abrupt warming in the Arctic (SIGMA)" Project (link to http://www.mri-jma.go.jp/Dep/cl/cl6/sigma/sigma-e.html) supported by Japan Society for the Promotion of Science (JSPS), Grant-in-Aid for Scientific Research (S), number 23221004. The data set contain 1-hourly meteorological and snow parameters measured at sites of SIGMA-A and SIGMA-B on the northwest Greenland since summer 2012.SIGMA-A is located on the Greenland ice sheet and SIGMA-B on Qaanaaq ice cap. The measured parameters are air temperature, relative humidity, wind speed, wind direction, air pressure, snow height, downward and upward components of shortwave, near-infrared and longwave radiant flux densities, and snow temperatures. The measured data were received from the ARGOS satellite network in semi-real time every day. Photos of these AWSs are presented in SIGMA Project HP.
The archive contains the monitored values of air pressure, heights of geopotential surface, air temperature, dew point deficit, and wind direction and speed at the ground level and at standard isobaric surfaces; level of tropopause; levels of specific points on air temperature and humidity, wind speed; level of maximal wind and wind rotation level, as well as data about cloudiness during radio sounding. The Finnish VAISALA DigiCora III MW31 system and RS-92-SGP sounds have been used for soundings. During the periods of special observations in the frame of the Year of Polar Prediction (February - March, July - September 2018), additional soundings had been executed at 12 UTC with support of National Institute of Polar Research of Japan (NIPR). This data set is a summary of YoPP-SOP1 and SOP2 data.
This repository includes datasets for the ice nucleating particle samples collected in Svalbard. The data on the ice nucleation active site densities per unit mass (n_m) for glacial outwash sediments (before and after H2O2 treatment) were obtained from the samples collected at two points near the glacier Broggerbreen in Svalbard. The data on the number concentrations of atmospheric ice nucleating particles (N_INP) were obtained from the samples collected at the Zeppelin Observatory in Ny-Alesund, Svalbard, during the intensive measurements campaigns in July 2016 (6 samples) and March 2017 (7 samples). The 95% confidence intervals for these data are also presented.

This dataset contains humidity and temperature profiles from the NCAS Humidity And Temperature PROfilers (HATPRO) scanning radiometer on board the Alliance research vessel for the Iceland Greenland seas Project (IGP).
The Iceland Greenland seas Project (IGP) was an international project involving the UK, US a Norwegian research communities. The UK component was funded by NERC, under the Atmospheric Forcing of the Iceland Sea (AFIS) project (NE/N009754/1)
In-situ airborne observations collected during flight 293-306 in March 2018 by the Meteorological Airborne Science Instrumentation (MASIN) on board the British Antarctic Survey (BAS) Twin-otter aircraft for the Iceland Greenland seas Project (IGP) including the Atmospheric Forcing of the Iceland Sea (AFIS) project. This dataset is a quality-controlled revision of the core meteorological data, generated at the University of East Anglia (UEA). Data were collected over the Iceland and Greenland Sea area.
This dataset contains meteorological, sea water temperature, surface ocean currents and wave height, direction and period measurements from a Seawatch Wavescan meteorological buoy deployed in the northwest Iceland Sea for the Iceland Greenland seas Project (IGP). This was an international project involving the UK, US a Norwegian research communities. The UK component was funded by NERC, under the Amospheric Forcing of the Iceland Sea (AFIS) project (NE/N009754/1). The Seawatch Wavescan meteorological buoy was deployed during the first leg of the NATO Research Vessel Alliance cruise, on 21 February 2018. Its position in the northwest Iceland Sea was strategically placed adjacent to a subsurface mooring in the Eggvin Offset. The dataset contains standard meteorological variables, surface ocean currents and wave height, direction and period from the buoy. Sea water temperature measurements at 8 m depth from the co-located mooring beneath the buoy are included to replace failed sea surface temperature measurements from the buoy under the reasonable assumption that this was still within the surface ocean mixed layer in this region. Similarly, pressure measurements that failed for roughly half of the deployment are replaced by surface layer estimates from ECMWF's ERA5 reanalysis product interpolated to the position of the meteorological buoy, corroborated for the period the sensor was working. Otherwise the buoy worked well for 2.5 months, until it broke loose from its anchor and stopped recording on 6 May 2018 and was recovered soon after. Also provided in the dataset are bulk aerodynamic flux estimates generated using the COARE3.0a algorithm.
