  • Feasibility of active handheld NDVI sensors for monitoring of lichen ground cover 
    Erlandsson, Rasmus; Arneberg, Marit Klemetsen; Tømmervik, Hans; Finne, Eirik Aasmo; Nilsen, Lennart; Bjerke, Jarle W. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Vegetation indices are corner stones in vegetation monitoring. However, previous field studies on lichens and NDVI have been based on passive sensors. Active handheld sensors, with their own light sources, enables high- ...

    Svalbard Integrated Arctic Earth Observing System (SIOS) is an international partnership of research institutions studying the environment and climate in and around Svalbard. SIOS is developing an efficient observing system, ...
  • Variation in albedo and other vegetation characteristics in non-forested northern ecosystems: the role of lichens and mosses 
    Finne, Eirik Aasmo; Bjerke, Jarle W.; Erlandsson, Rasmus; Tømmervik, Hans; Stordal, Frode; Tallaksen, Lena M. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Vegetation has a profound impact on climate through complex interactions and feedback loops, where especially regulation of albedo, the ratio of reflected to incoming solar radiation, is important at high latitudes. How ...
