Factors influencing the contribution of ion-induced nucleation in a boreal forest, Finland
ion-induced nucleation a boreal forest Finland
2010/8/12
We present the longest series of measurements so far (2 years and 7 months) made with an Ion-DMPS at the SMEAR II measurement station in Hyytiälä, Southern Finland. We show that the classifi...
Currents and turbulence within a kelp forest (Macrocystis pyrifera): Insights from a dynamically scaled laboratory model
Currents and turbulence a kelp forest Insights a dynamically scaled
2014/4/17
The effects of aMacrocystis pyriferaforest on currents and turbulence were investigated in a controlled laboratory setting using a dynamically matched 1/25-scale model. Two kelp configurations with su...
Effects of fetch and dissolved organic carbon on epilimnion depth and light climate in small forest lakes in southern Sweden
ight climate epilimnion depth
2014/4/16
We sampled small (0.03 to 3.3 km2
surface area) forest lakes in southern Sweden during two summers to
investigate how concentration of dissolved organic carbon (DOC) and lake size influence epilimni...
Simulation of snow accumulation and melt in needleleaf forest environments
needleleaf forest environments snow accumulation
2014/4/3
Drawing upon numerous field studies and modelling exercises of snow processes, the Cold Regions Hydrological Model (CRHM) was developed to simulate the four
season hydrological cycle in cold re...
A hillslope forest floor (duff) water budget and the transition to local control
forest fl oor water budget hillslope hydrology local control duff layer
2014/4/3
The partially decomposed organic layer (duff: F and H layers) of the forest floor is an important boundary between the soil
and atmospheric processes. Here we use both empirical data and a thre...
A comparison of dry and wet season aerosol number fluxes over the Amazon rain forest
dry and wet season aerosol number the Amazon rain forest
2010/8/12
Vertical number fluxes of aerosol particles and vertical fluxes of CO2 were measured with the eddy covariance method at the top of a 53 m high tower in the Amazon rain forest as part of the LBA (The L...
The role of sulphates and organic vapours in growth of newly formed particles in a eucalypt forest
sulphates and organic vapours newly formed particles a eucalypt forest
2010/8/12
The influence of biogenic particle formation on climate is a well recognised phenomenon. To understand the mechanisms underlying the biogenic particle formation, determining the chemical composition o...
Organic nitrogen in PM2.5 aerosol at a forest site in the Southeast US
Organic nitrogen PM2.5 aerosol forest site Southeast US
2010/3/5
There is growing evidence that organo-nitrogen compounds may constitute a significant fraction of the aerosol nitrogen (N) budget. However, very little is known about the abundance and origin of this ...
Tracing the fate of atmospheric nitrate deposited onto a forest ecosystem in Eastern Asia using Δ17O
atmospheric nitrate forest ecosystem Eastern Asia
2010/2/21
The stable isotopic compositions of nitrate in precipitation (wet deposition) and groundwater (spring, lake, and stream water) were determined for the island of Rishiri, Japan, so as to use the 17O an...
Forest decline caused by high soil water conditions in a permafrost region
Forest decline high soil water conditions permafrost region
2010/2/20
In the permafrost region near Yakutsk, eastern Siberia, Russia, annual precipitation (June–May) in 2005–2006 and 2006–2007 exceeded the 26-year (1982–2008) mean of 222±68 mm by 185 mm and 128 mm, resp...

Carbonyl sulfide exchange in a temperate loblolly pine forest grown under ambient and elevated CO2
Carbonyl sulfide loblolly pine forest CO2
2010/2/1
Vegetation, soil and ecosystem level carbonyl sulfide (COS) exchange was observed at Duke Forest, a temperate loblolly pine forest, grown under ambient (Ring 1, R1) and elevated (Ring 2, R2) CO2. Duri...
Needle age-related and seasonal photosynthetic capacity variation is negligible for modelling yearly gas exchange of a sparse temperate Scots pine forest
Needle age-related and seasonal photosynthetic capacity variation a sparse temperate Scots pine forest
2010/1/21
In this study, we quantified the predictive accuracy loss involved with omitting photosynthetic capacity variation for a Scots pine (Pinus sylvestris L.) stand in Flanders, Belgium. Over the course of...
Autumn temperature and carbon balance of a boreal Scots pine forest in Southern Finland
Autumn temperature carbon balance a boreal Scots pine forest Southern Finland
2010/1/21
We analyzed the dynamics of carbon balance components: gross primary production (GPP) and total ecosystem respiration (TER), of a boreal Scots pine forest in Southern Finland. The main focus is on inv...
