Science of the Total EnvironmentSvalbard, located between 76°30'N and 80°50'N, is among the regions in the world with the most rapid temperature increase. We processed a cloud-free time-series of MODIS-NDVI for Svalbard. The dataset is interpolated to daily data during the 2000-2022 period with 232 m pixel resolution.

A statistical study of polar cap flow channels observed in both hemispheres using SuperDARN radars
Journal of Space Weather and Space Climate, 2022 This paper details the first large-scale, interhemispheric statistical study into ionospheric fast flow (>900 m/s) channels in the polar cap using the SuperDARN radar network.

Electron precipitation characteristics during isolated, compound, and multi-night substorm events [PDF]
Annales Geophysicae, 2021 A set of 24 isolated, 46 compound, and 36 multi-night substorm events from the years 2008–2013 have been analysed in this study. Isolated substorm events are defined as single expansion–recovery phase pairs, compound substorms consist of multiple phase ...

Auroral all-sky camera calibration [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2014 A two-step procedure to calibrate the spectral sensitivity to visible light of auroral all-sky cameras is outlined. Center pixel response is obtained by the use of a Lambertian surface and a standard 45 W tungsten lamp.

The Ice‐Free Topography of Svalbard [PDF]
Geophysical Research Letters, 2018 Abstract We present a first version of the Svalbard ice‐free topography (SVIFT1.0) using a mass conserving approach for mapping glacier ice thickness. SVIFT1.0 is informed by more than 1 million point measurements, totalling more than 8,700 km of thickness profiles.
