Arctic greening from warming promotes declines in caribou populations
Fauchald, Per; Park, Taejin; Tømmervik, Hans; Myneni, Ranga B.; Hausner, Vera Helene (Journal article; Peer reviewed, 2017)Themigratory tundra caribou herds in North America follow decadal population cycles, and browsing from abundant caribou could be expected to counteract the current climate-driven expansion of shrubs in the circumpolar ... -
Changes in growing season duration and productivity of northern vegetation inferred from long-term remote sensing data
Park, Taejin; Ganguly, Sangram; Tømmervik, Hans; Euskirchen, Eugénie S.; Høgda, Kjell Arild; Karlsen, Stein Rune; Brovkin, Victor; Nemani, Ramakrishna R.; Myneni, Ranga B. (Journal article; Peer reviewed, 2016)Monitoring and understanding climate-induced changes in the boreal and arctic vegetation is critical to aid in prognosticating their future.Weused a 33 year (1982–2014) long record of satellite observations to robustly ... -
Changes in timing of seasonal peak photosynthetic activity in northern ecosystems
Park, Taejin; Chen, Chi; Macias-Fauria, Marc; Tømmervik, Hans; Choi, Sungho; Winkler, Alexander; Bhatt, Uma S.; Walker, Donald A.; Piao, Shilong; Brovkin, Victor; Nemani, Ramakrishna R.; Myneni, Ranga B. (Journal article; Peer reviewed, 2019)Seasonality in photosynthetic activity is a critical component of seasonal carbon, water and energy cycles in the Earth system. This characteristic is a consequence of plant’s adaptive evolutionary processes to a given set ... -

China and India lead in greening of the world through land-use management
Chen, Chi; Park, Taejin; Wang, Xuhui; Piao, Shilong; Xu, Baodong; Chaturvedi, Rajiv K.; Fuchs, Richard; Brovkin, Victor; Ciais, Philippe; Fensholt, Rasmus; Tømmervik, Hans; Bala, Govindasamy; Zhu, Zaichun; Nemani, Ramakrishna R.; Myneni, Ranga B. (Journal article; Peer reviewed, 2019)Satellite data show increasing leaf area of vegetation due to direct factors (human land-use management) and indirect factors (such as climate change, CO2 fertilization, nitrogen deposition and recovery from natural ... -
Legacies of Historical Exploitation of Natural Resources Are More Important Than Summer Warming for Recent Biomass Increases in a Boreal–Arctic Transition Region
Tømmervik, Hans; Bjerke, Jarle W.; Park, Taejin; Hanssen, Frank Ole; Myneni, Ranga B. (Peer reviewed; Journal article, 2019)Eurasian forest cover at high northern latitudes (> 67 N) has increased in recent decades due to stimulatory effects of global warming, but other factors may be important. The objective of this study is to compare the ... -
The northernmost hyperspectral FLoX sensor dataset for monitoring of high-Arctic tundra vegetation phenology and Sun-Induced Fluorescence (SIF)
Tømmervik, Hans; Julitta, Tommaso; Nilsen, Lennart; Park, Taejin; Burkart, Andreas; Ostapowicz, Katarzyna Anna; Karlsen, Stein Rune; Parmentier, Frans-Jan W.; Pirk, Norbert; Bjerke, Jarle W. (Peer reviewed; Journal article, 2023)A hyperspectral field sensor (FloX) was installed in Adventdalen (Svalbard, Norway) in 2019 as part of the Svalbard Integrated Arctic Earth Observing System (SIOS) for monitoring vegetation phenology and Sun-Induced ...
