    Blind Hyperspectral Unmixing using Autoencoders : A Critical Comparison 
    Pálsson, Burkni; Sveinsson, Jóhannes Rúnar; Úlfarsson, Magnús Örn (2022-01-01)
    Deep learning has shown to be a powerful tool and has heavily impacted the data-intensive field of remote sensing. As a result, the number of published deep learning-based spectral unmixing techniques is proliferating. Blind hyperspectral unmixing (HU) ...

    Determination of eddy dissipation rate by Doppler lidar in Reykjavik, Iceland 
    Yang, Shu; Petersen, Guðrún Nína; von Löwis, Sibylle; Preißler, Jana; Finger, David C. (Wiley, 2020-09)
    The temporal and spatial scale of atmospheric turbulence can be highly dynamic, requiring sophisticated methods for adequate detection and monitoring with high resolution. Doppler light detection and ranging (lidar) systems have been widely used to ...

    On the relationship between the 500 hPa height fluctuations and the atmosphere thickness over Iran and the Middle East 
    Rousta, Iman; Doostkamian, Mehdi; Olafsson, Haraldur; Ghafarian Malamiri, Hamid Reza; Zhang, Hao; Taherian, Allah Morad; SARIF, MD OMAR; Gupta, Rajan Dev; Monroy-Vargas, E. R. (Tethys, Journal of Weather and Climate of the Western Mediterranean, 2019)
    This paper focuses on the relationship between the 500 hPa height fluctuations and the associative atmosphere thickness (AT) over Iran and the Middle East between 1961 and 2013. For this purpose, atmospheric Geopotential Height (HGT) data of the 1000 ...

    Quantifying the Effect of Wind on Volcanic Plumes: Implications for Plume Modeling 
    Dürig, Tobias; Guðmundsson, Magnús T.; Dioguardi, Fabio; Schmidt, Louise Steffensen (American Geophysical Union (AGU), 2023-01-13)
    The considerable effects that wind can have on estimates of mass eruption rates (MERs) in explosive eruptions based on volcanic plume height are well known but difficult to quantify rigorously. Many explicitly wind-affected plume models have the ...

    Stories vs. facts: triggering emotion and action-taking on climate change 
    Morris, Brandi S.; Chrysochou, Polymeros; Christensen, Jacob Dalgaard; Lund Orquin, Jacob; Barraza, Jorge; Zak, Paul J.; Mitkidis, Panagiotis (Springer Science and Business Media LLC, 2019-04-06)
    Climate change is an issue which elicits low engagement, even among concerned segments of the public. While research suggests that the presentation of factual information (e.g., scientific consensus) can be persuasive to some audiences, there is also ...

    Uptake and surface chemistry of SO2 on natural volcanic dusts 
    Urupina, Darya; Lasne, Jerome; romanias, manolis; Thiery, Vincent; Dagsson-Waldhauserova, Pavla; THEVENET, Frederic (Elsevier BV, 2019-11)
    V-dust (v-dust) is a highly variable source of natural particles in the atmosphere, and during the period of high volcanic activity it can provide a large surface for heterogeneous interactions with other atmospheric compounds. Icelandic v-dust was ...
