[REPORT SUMMARY] Aerosol fluxes and their measurement technique
Summary:
Vertical particle fluxes were measured applying condensation particle counter (CPC) model TSI 3010 in the eddy covariance technique. The EC is a widely used method to measure gas fluxes. Different aspects of the method have been described. During the measurement cam...

[REPORT SUMMARY] Frequency of aerosol particle formation in boreal forest site
Summary:
Continuous measurements (every 10 min) of submicron aerosol number size distribution shows ca 50 days per year with clearly detectable aerosol particle formation events. Almost 20% of those events will continue sufficiently long to produce particles with diameter ov...

[REPORT SUMMARY] The contribution of reactive halogen species to the oxidation capacity of the troposphere reactive halogen species
Tropospheric ozone is responsible for approximately 15% of the antropogenically caused greenhouse effect. It is also the precursor of the hydroxyl-radical, the most important atmospheric oxidant, and thus also responsible for the self-cleaning capacity of the atmosphere. Field...

During the time frame of COBRA, new data on gas-phase, photochemical and heterogeneous reactions of bromine species involved in stratospheric chemistry became available. Chemical models were used to assess the impact of these data on bromine chemistry and ozone depletion. Firs...

[REPORT SUMMARY] Studies on processes responsible for distribution and evolution of O3 and H2O in troposphere and lower stratosphere
Summary: The existence of ozone-rich transients in the tropical and subtropical high troposphere has been discovered from MOZAIC data obtained during flights crossing the Equator. Several explanations have been proposed, but this strongly suggests that the input of stratospher...

[REPORT SUMMARY] Combination TOPEX/POSEIDON and ERS data sets
Summary : The data sets provides a combined view of the ocean altimetry. The TOPEX and ERS observations are complementary, one more suited to high resolution in space and the other to high resolution in time. Combination of the two has allowed to improve the value of the obser...

[REPORT SUMMARY] Kinetic and thermodynamic data for heterogeneous reactions
The strategy for investigation of heterogeneous reactions has been to investigate uptake of single gas-phase reactants onto surfaces with and without addition of a second reactant. In this way the adsorption characteristics of the individual reactant molecules could be defined...

[REPORT SUMMARY] Validation of the PROMETHEUS forest fire management system
Wildland fires are responsible for most damage and environmental impairment of forest ecosystems in the Mediterranean region. As a consequence, the current fire management policy is to fight fired aggressively in all cases, although most of the fires are caused by man himself....
