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...
Sensitivity analyses of OH missing sinks over Tokyo metropolitan area in the summer of 2007
Sensitivity analyses OH missing sinks Tokyo metropolitan area
2009/12/3
OH reactivity is one of key indicators which reflect impacts of photochemical reactions in the atmosphere. An observation campaign has been conducted in the summer of 2007 at the heart of Tokyo metrop...
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...
Equilibrium of sinks and sources of sulphate over Europe: comparison between a six-year simulation and EMEP observations
sulphate Europe EMEP
2009/7/15
Sulphate distributions were simulated with a global chemistry transport model. A chemical scheme describing the sulphur cycle and the parameterisations of the main sinks for sulphate aerosols were inc...
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...
