Effects of aerosols on the properties of deep convective clouds

Creator:: Brown, Daniel A.
Abstract:: Aerosols are tiny particles that serve as nuclei for cloud droplet and ice crystal formation. Increases in aerosol concentration lead to clouds with smaller but more numerous droplets. Some recent studies have found evidence that ice crystal size in deep convective clouds is also reduced by elevated aerosol concentrations. In...

A complex signal to noise problem : determining the aerosol indirect effect from observations of ship tracks in AVHRR data

Creator:: Walsh, Christopher D.
Abstract:: Cloud reflectivity is a function of cloud liquid water content and droplet number concentration. Since cloud droplets form around pre-existing aerosol particles, cloud droplet number concentration depends on the availability of particles that can serve as cloud condensation nuclei. Given constant liquid water amount, increased availability of cloud condensation nuclei...

Factors influencing the atmospheric aerosol composition at two sites in western Oregon

Creator:: Ko, Lih-jong
Abstract:: Fine and coarse particles were collected for eight weeks during the summer of 1991, at a coastal site (Yaquina Head) and a non-industrial site (Corvallis) in Western Oregon to characterize the aerosol composition and evaluate whether the sites are appropriate for sampling "background" marine air. Concentrations of up to 11...

Response of marine stratus to successive polluting events by ships

Creator:: Sechrist, B.
Abstract:: Ship tracks have proven to be an ideal laboratory for studying the response of marine stratocumulus to an increase in aerosol pollution. Here the response of already polluted marine stratocumulus to further pollution was examined by studying the clouds where two ship tracks cross. 78 crossings of ship tracks were...

Effects of solar heating on the indirect effect of aerosols as deduced from observations of ship tracks

Creator:: Christensen, Matthew W.
Abstract:: One kilometer Moderate Resolution Imaging Spectroradiometer (MODIS) observations for Terra (morning) and Aqua (afternoon) satellites were used to follow the morning to afternoon evolution of marine stratocumulus clouds that were affected by ship stack exhaust. The observations covered the summer months of 2002-2003 and August 2007 for marine layers off...

Assessing the effectiveness and environmental impacts of using natural flocculants to manage turbidity

Creator:: Kegley, Laura J.
Abstract:: The objective of this research was to determine the feasibility of using chitosan as a natural flocculant to control turbidity during in-stream construction work. A series of field tests in Oak Creek, Corvallis, OR were conducted in order to test the effectiveness for turbidity control and the environmental impacts of...

Ecological Consequences of Marine Debris: Understanding Large-Scale Species Transport on Tsunami Debris and Research Priorities in Oregon

Creator:: Gillman, Reva A.
Abstract:: The release of marine debris into the oceans and seas is a global issue of growing concern. These materials are harmful to marine environments and can also transport non-native species to novel habitats. Non-native species floating on marine litter is one of the lesser known impacts associated with marine debris....

The agronomic, environmental, and economic implications of the introduction of terbacil for weed control in Oregon commercial peppermint operations

Creator:: Harris, James O.
Abstract:: The use of terbacil for weed control was adapted by a high percentage of Oregon peppermint growers soon after its introduction in 1967. To help clarify some of the implications of terbacil usage, three studies were undertaken to collect information concerning (a) the movement and build-up of terbacil in various...
