Abstract. We applied a site evaluation approach combining Lagrangian Stochastic footprint modeling with quality assessment for eddy-covariance data to 25 forested sites of the CarboEurope-IP network. The analysis addresses spatial representativeness flux measurements, instrumental effects on quality, patterns in and performance coordinate rotation method. Our findings demonstrate that application filter could strengthen database, since only one third is situated truly homogeneous terrain....
This paper demonstrates that atmospheric inversions of CO 2 are a reliable tool for estimating regional fluxes. We compare results an inversion over 18 days and 300 × km domain in southwest France against independent measurements fluxes from aircraft towers. The used concentration towers while the data included 27 transects 5 flux reduces mismatch between prior fluxes, improving both spatial temporal structures. present mesoscale improves by 30% distances few hundreds around measurement locations.
Large coherent structures over vegetation canopies are responsible for a substantial part of the turbulent transfer momentum, heat and mass between canopy atmosphere. As forested landscapes often fragmented, edge regions may be importance in transfer. The development from leading forest is investigated here first time. For this purpose, flow clearing–forest pattern simulated using Advanced Regional Prediction System (ARPS). In previous studies code has been modified so as to simulate flows...
Abstract. The residence time of bacterial cells in the atmosphere is predictable by numerical models. However, estimations their aerial dispersion as living entities are limited a lack information concerning survival rates and behavior relation to atmospheric water. Here we investigate viability ice nucleation (IN) activity typical active bacteria (Pseudomonas syringae P. fluorescens) when airborne cloud simulation chamber (AIDA, Karlsruhe, Germany). Cell suspensions were sprayed into...
Abstract The current emphasis on global climate studies has led the scientific community to set up a number of sites for measuring long‐term biospheric fluxes, and develop wide range biosphere–atmosphere exchange models. This paper presents new model this type, which been developed pine forest canopy. In most coniferous species canopy layer is well separated from understorey several cohorts needles coexist. It was therefore found necessary distinguish vegetation layers and, in each layer,...
The Second Global Soil Wetness Project (GSWP-2) is an initiative to compare and evaluate 10-year simulations by a broad range of land surface models under controlled conditions. A major product GSWP-2 the first global gridded multimodel analysis state variables fluxes for use meteorologists, hydrologists, engineers, biogeochemists, agronomists, botanists, ecologists, geographers, climatologists, educators. Simulations 13 from five nations have gone into production analysis. are driven...
The current emphasis on global climate studies has led the scientific community to set up a number of sites for measuring long‐term biosphere‐atmosphere net CO 2 exchange (net ecosystem exchange, NEE). Partitioning this flux into its elementary components, assimilation ( F A ), and respiration R remains necessary in order get better understanding biosphere functioning design surface models. Noting that have different isotopic signatures, we evaluate potential 13 measurements air (combined...
Stable CO 2 isotope measurements are increasingly used to partition the net exchange between terrestrial ecosystems and atmosphere in terms of nonfoliar respiration ( F R ) photosynthesis A order better understand variations this exchange. However, accuracy partitioning strongly depends on isotopic disequilibrium these two gross fluxes, a rigorous estimation errors is needed. In study, we account for propagate uncertainties all mass balance equations get accurate estimates . We apply our...
