The importance of transport model uncertainties for the estimation of CO2 sources and sinks using satellite measurements
transport model uncertainties CO2 sources and sinks satellite measurements
2010/11/3
This study presents a synthetic model intercomparison to investigate the importance of transport model errors for estimating the sources and sinks of CO2 using satellite measurements. The experiments ...
Temporal variability, sources, and sinks of C1-C5 alkyl nitrates in coastal New England
Temporal variability C1-C5 alkyl nitrates coastal New England
2010/2/21
Seven C1-C5 alkyl nitrates were measured both on the mainland and off the coast of New Hampshire using gas chromatographic techniques. Five separate data sets are presented to characterize the seasona...
Ammonia sources and sinks in an intensively managed grassland canopy
Ammonia sources sinks grassland canopy
2010/1/21
Grasslands represent canopies with a complex structure where sources and sinks of ammonia (NH3) may coexist at the plant level. Moreover, management practices such as mowing, hay production and grazin...
Technical Note: In-situ quantification of aerosol sources and sinks over regional geographical scales
In-situ quantification aerosol sources regional geographical scales
2009/7/23
In order to obtain the source/sink functions for atmospheric particulates located on the planetary surface or elevated in the atmosphere; direct aerosol emission measurements are required. For this pu...
Structure of the transport uncertainty in mesoscale inversions of CO2 sources and sinks using ensemble model simulations
transport uncertainty mesoscale inversions CO2 sources sinks model simulations
2010/1/20
We study the characteristics of a statistical ensemble of mesoscale simulations in order to estimate the model error in the simulation of CO2 concentrations. The ensemble consists of ten members and t...

2010/1/20
The current paper reviews the experimental setup of the CarboEurope Experimental Strategy (CERES) campaigns with the aim of providing an overview of the instrumentation used, the data-set and associat...
Radicals in the marine boundary layer during NEAQS 2004: a model study of day-time and night-time sources and sinks
marine boundary layer NEAQS Radicals
2009/5/15
This paper describes a modelling study of several HOx and NOx species (OH, HO2, organic peroxy radicals, NO3 and N2O5) in the marine boundary layer. A model based upon the Master Chemical Mechanism (M...
Geographical Variability of the Internal Wave Field：A Search for Sources and Sinks
Geographical Variability Internal Wave Field
2009/3/7
Internal wave records from a variety of deep water locations in the North Atlantic have been reduced by common analysis methods in a search for systematic deviations from a universal spectral model. S...
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...
