Climatic versus biotic constraints on carbon and water fluxes in seasonally drought-affected ponderosa pine ecosystems [PDF]

open access: yes, 2004
We investigated the relative importance of climatic versus biotic controls on gross primary production (GPP) and water vapor fluxes in seasonally drought-affected ponderosa pine forests. The study was conducted in young (YS), mature (MS), and old stands (

Effects of CeO2 on Viscosity, Structure, and Crystallization of Mold Fluxes for Casting Rare Earths Alloyed Steels

open access: yesMetals, 2019
The CaO-Al2O3-based mold fluxes are proposed for the Ce-bearing heavy rail steel continuous casting because of the low reactivity. Effects of CeO2 on the melting temperature, the viscous property, and the crystallization behavior of the CaO-Al2O3-Li2O ...

Variability of carbon dioxide fluxes in heterogeneous urban environments : from street canyon to neighborhood scale [PDF]

open access: yes, 2015
High carbon dioxide (CO2) emissions in cities are a consequence of high energy consumption by a dense population. Fossil fuel related emissions from urban areas contribute to the increase in average atmospheric concentrations of CO2.

High-resolution land surface fluxes from satellite and reanalysis data (HOLAPS v1.0): evaluation and uncertainty assessment [PDF]

open access: yesGeoscientific Model Development, 2016
Surface water and energy fluxes are essential components of the Earth system. Surface latent heat fluxes provide major energy input to the atmosphere. Despite the importance of these fluxes, state-of-the-art data sets of surface energy and water fluxes ...

Precipitation as driver of carbon fluxes in 11 African ecosystems [PDF]

open access: yes, 2008
This study reports carbon and water fluxes between the land surface and atmosphere in eleven different ecosystems types in Sub-Saharan Africa, as measured using eddy covariance (EC) technology in the first two years of the CarboAfrica network operation ...

Quantifying global marine isoprene fluxes using MODIS chlorophyll observations [PDF]

open access: yes, 2005
We report global distributions of marine isoprene flux, whose source is estimated by combining an empirical relationship for isoprene production rate with MODIS satellite chlorophyll observations from 2001.

Chemical Weathering of Loess and Its Contribution to Global Alkalinity Fluxes to the Coastal Zone During the Last Glacial Maximum, Mid‐Holocene, and Present

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Loess sediments are windblown silt deposits with, in general, a carbonate grain content of up to 30%. While regionally, loess was reported to increase weathering fluxes substantially, the influence on global weathering fluxes remains unknown.

Modelling time-integrated fluxes of CO2 and CH4 in peatlands: A review [PDF]

open access: yesMires and Peat, 2019
There is widespread interest in estimating annual carbon dioxide (CO2) and methane (CH4) budgets for peatlands using data collected from flux chambers. Flux-chamber measurements are a snapshot of the conditions on a particular site and may not adequately
