Dornier hyperspectral point cloud data (HySpex VNIR-1800)


Airborne hyperspectral point cloud data acquired with a HySpex Mjolnir VNIR (400–1000 nm) spectrometer mounted on Lufttransport's aircraft (Dornier DO228 POD). The sensor records 1800 spatial pixels per scan line with 186 spectral channels. Precise geolocation is derived from Applanix POS AV 410 navigation data and a 5 m DEM from the Norwegian Polar Institute, with raytracing used to produce 3D georeferenced point clouds linked to full spectra. Products can be visualised as point clouds, converted to 3D meshes, or rasterised to geocoded imagery. Applications include cryosphere, ocean,…

Arctic Sea Ice Age Climate Data Record v2.1


This climate data record of sea ice age is obtained from coarse resolution ice drift and conentration OSI SAF products. The processing chain features: 1) Lagrangian advection of ice age fractions, 2) Weighted averaging of fractions.

48-hour (0-24h and 25-48h) PM10 Concentrations Forecast with the AdaptedCrossformer model at European Environmental Agency (EEA) Monitoring Stations (2024)


These datasets contain hourly PM10 concentrations between 0 and 24 hours (`2024_AURORAE-d0_TIME.cdf`) and between 25 and 48 hours (2024_AURORAE-d1_TIME.cdf`) from the forecast initialization at 164 air quality monitoring stations across Europe for the year 2024. Each variable represents a unique EEA station, identified by a station code. Data are provided in NetCDF format, structured as time series. Missing values occur when it is impossible to perform the forecast for a certain time span due to a lack of input data for the model. For completeness and comparison with the EEA dataset, all…

Global tilted irradiance on 25 planes measured in Svalbard


These files includes a time series of global tilted irradiance (GTI) measurements every 30 second in the Svalbard region. The measurements were acquired with a 25-pyranometer array called GLOB, mounted in the shape of a rhombicuboctahedron. They consist of solar irradiance recorded with Apogee SP-110 pyranometers on 25 different planes. Each GTI component is labeled with the format "azimuth_tilt". We also included the solar angles associated to each timestamp, calculated with pvlib.

New version of Dornier hyperspectral point cloud data (HySpex VNIR-1800)

By laraf |

A new version of the "Dornier hyperspectral point cloud data (HySpex VNIR-1800)" has been published. This new version can be found at https://doi.org/10.21343/mfdy-t860. This is an updated version of the data previously published at https://doi.org/10.21343/4c39-h373, with increased precision in the X, Y, lat, and lon variables. 

The older version will be scheduled for deletion after a grace period. We encourage data consumers to use the latest version of the dataset.  

Major changes in the metadata catalogue

By laraf |

On Monday 20th of March the SolR back-end for the metadata catalogue of the data portal will be changed.

Some major modifications will be present, including changes of metadata identifiers for some of the records.

A namespace prefix no.met.adc for all records managed by the Arctic Data Centre (adc.met.no) is now added.

Some records might be missing at the beginning, but we are working on filling these gaps.
