Publikováno v: Atmospheric Chemistry and Physics, Vol 23, Pp 7839-7858 (2023)

The ecosystem–atmosphere flux of biogenic volatile organic compounds (BVOCs) has important impacts on tropospheric oxidative capacity and the formation of secondary organic aerosols, influencing air quality and climate. Here we present within-canop

Publikováno v: Atmospheric Measurement Techniques, Vol 14, Pp 6119-6135 (2021)

We present a statistical framework to identify regional signals in station-based CO2 time series with minimal local influence. A curve-fitting function is first applied to the detrended time series to derive a harmonic describing the annual CO2 cycle

Plant transpiration links physiological responses of vegetation to water supply and demand with hydrological, energy, and carbon budgets at the land–atmosphere interface. However, despite being the main land evaporative flux at the global scale, tr

Evaluation and optimization of ICOS atmosphere station data as part of the labeling process

Publikováno v: Atmospheric Measurement Techniques, Vol 14, Pp 89-116 (2021)

The Integrated Carbon Observation System (ICOS) is a pan-European research infrastructure which provides harmonized and high-precision scientific data on the carbon cycle and the greenhouse gas budget. All stations have to undergo a rigorous assessme

Retrieval and validation of forest background reflectivity from daily Moderate Resolution Imaging Spectroradiometer (MODIS) bidirectional reflectance distribution function (BRDF) data across European forests

Publikováno v: Biogeosciences, Vol 18, Pp 621-635 (2021)

Information about forest background reflectance is needed for accurate biophysical parameter retrieval from forest canopies (overstory) with remote sensing. Separating under- and overstory signals would enable more accurate modeling of forest carbon

The importance of micrometeorological variations for photosynthesis and transpiration in a boreal coniferous forest

Autor: G. Schurgers, F. Lagergren, M. Mölder, A. Lindroth

Publikováno v: Biogeosciences, Vol 12, Iss 1, Pp 237-256 (2015)

Plant canopies affect the canopy micrometeorology, and thereby alter canopy exchange processes. For the simulation of these exchange processes on a regional or global scale, large-scale vegetation models often assume homogeneous environmental cond

Impacts of stump harvesting on carbon dioxide, methane and nitrous oxide fluxes

Autor: P Vestin, M Mölder, N Kljun, Z Cai, A Hasan, J Holst, L Klemedtsson, A Lindroth

During 2010-2013, we investigated the effects of stump harvesting on greenide (N2O) with the flux-gradient technique at four experimental plots in a hemiboreal forest in Sweden. All plots were clear-cut and soil scarified and two of the plots were ad

Heat storage in forest biomass improves energy balance closure

Autor: A. Lindroth, M. Mölder, F. Lagergren

Publikováno v: Biogeosciences, Vol 7, Iss 1, Pp 301-313 (2010)

Temperature measurements in trunks and branches in a mature ca. 100 years-old mixed pine and spruce forest in central Sweden were used to estimate the heat storage in the tree biomass. The estimated heat flux in the sample trees and data on biomass d
