Estimating local-scale forest GPP in Northern Europe using Sentinel-2: Model comparisons with LUE, APAR, the plant phenology index, and a light response function
(Peer reviewed; Journal article, 2023-01-03)Northern forest ecosystems make up an important part of the global carbon cycle. Hence, monitoring local-scale gross primary production (GPP) of Northern forest is essential for understanding climatic change impacts on ... -
Image Classification by Integrating Reject Option and Prior Information
(Journal article; Peer reviewed, 2018-11-11)The accuracy in land-cover classification using remotely sensed imagery can be increased using Bayesian methods that incorporate prior probabilities of classes. However, estimating these prior probabilities can be expensive ... -
Method comparison of indirect assessments of understory leaf area index (LAIu): A case study across the extended network of ICOS forest ecosystem sites in Europe
(Peer reviewed; Journal article, 2021-05-31)Leaf area index (LAI) is a key ecological indicator for describing the structure of canopies and for modelling energy exchange between atmosphere and biosphere. While LAI of the forest overstory can be accurately assessed ... -
Use of models in large-area forest surveys: comparing model-assisted, model-based and hybrid estimation
(Journal article; Peer reviewed, 2016)This paper focuses on the use of models for increasing the precision of estimators in large-area forest surveys. It is motivated by the increasing availability of remotely sensed data, which facilitates the development of ... -
Yield Estimates by a Two-Step Approach Using Hyperspectral Methods in Grasslands at High Latitudes
(Journal article; Peer reviewed, 2019-02-16)Ruminant fodder production in agricultural lands in latitudes above the Arctic Circle is constrained by short and hectic growing seasons with a 24-hour photoperiod and low growth temperatures. The use of remote sensing to ...
