The JGrass-NewAge system for forecasting and managing the hydrological budgets at the basin scale: models of flow generation and propagation/routing
JGrass-NewAge system hydrological budgets
2014/12/9
This paper presents a discussion of the predictive capacity of the implementation of the semidistributed
hydrological modeling system JGrassNewAge.
Clouds, photolysis and regional tropospheric ozone budgets
Clouds photolysis regional tropospheric ozone budgets
2009/11/19
We use a three-dimensional chemical transport model to examine the shortwave radiative effects of clouds on the tropospheric ozone budget. In addition to looking at changes in global concentrations as...

Water and Salt Budgets Stratified Estuary
2009/10/29
Small tidal range, low salinity, moderate temperature and salinity stratification
during summer which becomes weaker during winter, abundant fresh water inflow
and connection through a shallow sill ...
Chemical Budgets and Chemical Quality of Snow and Runoff During Spring Snowmelt
Chemical Budgets Chemical Quality Spring Snowmelt
2009/10/28
In connection with water acidification and the subsequent disappearance of
fish populations and also massive fish kills during spring floods, particular
interest has been focused upon the fate and e...
Calcium Budgets for Catchments as Interpreted by Strontium Isotopes
Calcium Budgets Catchments Strontium Isotopes
2009/10/27
Strontium isotopes in precipitation, soil and runoff water can be used to establish
a ratio of wet plus dry deposited Sr to Sr released by weathering. This ratio
is especially enhanced in areas with...
Chinese rivers deliver about 5–10% of global freshwater input and 15–20% of the global continental sediment to the world ocean. We report the riverine fluxes and concentrations of major nutrients (nit...
Long-lived halocarbon trends and budgets from atmospheric chemistry modelling constrained with measurements in polar firn
Long-lived halocarbon atmospheric chemistry modelling polar firn
2009/6/22
The budgets of seven halogenated gases (CFC-11, CFC-12, CFC-113, CFC-114, CFC-115, CCl4 and SF6) are studied by comparing measurements in polar firn air from two Arctic and three Antarctic sites, and ...

Sulphur and nitrogen fluxes and budgets in the Bohemian Forest and Tatra Mountains during the Industrial Revolution (1850-2000)
emission deposition acidification
2009/3/24
Major fluxes of sulphur and dissolved inorganic nitrogen were estimated in Central European mountain ecosystems of the Bohemian Forest (forest lakes) and Tatra Mountains (alpine lakes) over the indust...
Effect on nitrate concentration in stream water of agricultural practices in small catchments in Brittany: I. Annual nitrogen budgets
nitrate diffuse pollution agricultural catchment
2009/3/17
The hydrological and biogeochemical monitoring of catchments has become a common approach for studying the effect of the evolution of agricultural practices on water resources. In numerous studies, t...
Balancing the books – a statistical theory of prospective budgets in Earth System science
balance budget sampling hypothesis test closing error
2009/3/12
An honest declaration of the error in a mass, momentum or energy balance, ε, simply raises the question of its acceptability: "At what value of ε is the attempted balance to be rejected?" Answering th...
Simulating nitrogen budgets in complex farming systems using INCA: calibration and scenario analyses for the Kervidy catchment (W. France)
diffuse pollution nitrate climate change model
2009/3/6
The integrated nitrogen model INCA (Integrated Nitrogen in Catchments) was used to analyse the nitrogen dynamics in a small rural catchment in Western France. The agrosystem studied is very complex, w...
Arguments on Oceanic Carbon Cycle of IPCC Assessments——A Test Using δ13C Budgets
IPCC CO2 budget δ13C isotope fractionation
2010/2/21
By comparing the global carbon cycle of the IPCC assessment reports in 1990, 1996, 2001 and 2007, it was found that despite the estimated sizes of the main carbon reservoirs and the fluxes between the...
Dissipation Mechanisms and the Importance of Eddies in Model Ocean Energy Budgets
Dissipation Mechanisms Ocean Energy Budgets
2009/2/16
The importance of mesoscale eddies in the basin energy budgets of closed-basin numerical model oceanic systems that attempt to resolve such motions varies greatly from calculation to calculation. In e...
Regional Eddy Vorticity Transport and the Equilibrium Vorticity Budgets of a Numerical Model Ocean Circulation
Regional Eddy Vorticity Transport Equilibrium Vorticity Numerical Model Ocean Circulation
2009/2/9
The dynamical balances of the mean flow of a numerical model ocean general circulation experiment are examined through evaluation of regional vorticity budgets. The instantaneous flow is strongly time...
