Present state of global wetland extent and wetland methane modelling: methodology of a model inter-comparison project (WETCHIMP)
global wetland extent wetland methane modelling model inter-comparison project
2014/12/12
The Wetland and Wetland CH4 Intercomparison of Models Project (WETCHIMP) was created to evaluate our present ability to simulate large-scale wetland characteristics and corresponding methane (CH4) emi...
Improved measurement of carbonaceous aerosol: evaluation of the sampling artifacts and inter-comparison of the thermal-optical analysis methods
carbonaceous aerosol the sampling artifacts the thermal-optical analysis methods
2010/9/21
The sampling artifacts (both positive and negative) and the influence of thermal-optical methods (both charring correction method and the peak inert mode temperature) on the split of organic carbon (O...
Inter-comparison of source apportionment models for the estimation of wood burning aerosols during wintertime in an Alpine city (Grenoble, France)
source apportionment models wood burning aerosols wintertime an Alpine city
2010/8/13
The emission of organic aerosols (OA) in the ambient air by residential wood burning is nowadays a subject of great scientific concern and a growing number of studies aim at apportioning the influence...
Field inter-comparison of eleven atmospheric ammonia measurement techniques
Field inter-comparison eleven atmospheric ammonia measurement techniques
2010/2/8
Eleven instruments for the measurement of ambient concentrations of atmospheric ammonia gas (NH3), based on eight different measurement methods were inter-compared above an intensively managed agricul...
Inter-comparison of ammonia fluxes obtained using the Relaxed Eddy Accumulation technique
Inter-comparison ammonia fluxes Relaxed Eddy Accumulation technique
2010/1/21
The exchange of Ammonia (NH3) between grassland and the atmosphere was determined using Relaxed Eddy Accumulation (REA) measurements. The use of REA is of special interest for NH3, since the determina...
Inter-Comparison of two Snow Models with Different Complexity using Data from an Alpine Site
Inter-Comparison Snow Models Alpine Site
2009/10/22
This contribution describes the modelization of the snow cover evolution with the two physically based snow models CROCUS and ESCIMO at the Col de Porte station (1,325 m a.s.l., French Alps) for the ...
Inter-comparison of four different carbon monoxide measurement techniques and evaluation of the long-term carbon monoxide time series of Jungfraujoch
carbon monoxide measurement techniques long-term carbon monoxide time series Jungfraujoch
2009/6/16
Despite the importance of carbon monoxide (CO) for the overall oxidative capacity of the atmosphere, there is still considerable uncertainty in ambient measurements of CO. To address this issue, an in...
Ammonia fluxes in relation to cutting and fertilization of an intensively managed grassland derived from an inter-comparison of gradient measurements
Ammonia fluxes cutting fertilization grassland inter-comparison gradient measurements
2010/1/20
Quantification of ammonia (NH3) land-atmosphere exchange is required for atmospheric modelling and assessment of nitrogen deposition, yet flux measurement methods remain highly uncertain. To address t...
Inverse modeling of CO2 sources and sinks using satellite data: a synthetic inter-comparison of measurement techniques and their performance as a function of space and time
CO2 sources synthetic inter-comparison function of space and time
2009/2/24
Currently two polar orbiting satellite instruments measure CO2 concentrations in the Earth's atmosphere, while other missions are planned for the coming years. In the future such instruments might be...
The UV-A and visible solar irradiance spectrum: inter-comparison of absolutely calibrated, spectrally medium resolution solar irradiance spectra from balloon- and satellite-borne measurements
UV-A and visible solar irradiance spectrum spectrally medium resolution solar irradiance spectra
2009/2/12
Within the framework of the ENVISAT/-SCIAMACHY satellite validation, solar irradiance spectra are absolutely measured at moderate resolution in the UV/visible spectral range (in the UV from 316.7-418...
