Tropospheric Ozone And Co Over North Atlantic For The Past Decade, Mark F. Weise
Tropospheric Ozone And Co Over North Atlantic For The Past Decade, Mark F. Weise
Theses and Dissertations
We investigate how declines in US emissions of CO and O3 precursors have impacted the lower free troposphere over the North Atlantic. We use seasonal observations for O3 and CO from the PICO-NARE project for the period covering 2001 to 2010. Observations are used to verify model output generated by the GEOS-Chem 3-D global chemical transport model. Additional satellite data for CO from AIRS/Aqua and for O3 from TES/Aura were also used to provide additional comparisons; particularly for fall, winter, and spring when PICO-NARE coverage is sparse. We find GEOS-Chem captures the seasonal cycle for CO and O3 well compared …
Study Of Water Use And Supply In The District Of Independencia, Peru, Fletcher A. Mckenzie
Study Of Water Use And Supply In The District Of Independencia, Peru, Fletcher A. Mckenzie
Theses and Dissertations
Peru is a developing country with abundant fresh water resources, yet the lack of infrastructure leaves much of the population without access to safe water for domestic uses. The author of this report was a Peace Corps Volunteer in the sector of water & sanitation in the district of Independencia, Ica, Peru. Independencia is located in the arid coastal region of the country, receiving on average 15 mm of rain annually. The water source for this district comes from the Pisco River, originating in the Andean highlands and outflowing into the Pacific Ocean near the town of Pisco, Peru.

Climatological Study Of Transport To The Pico-Nare Site Using Atmospheric Backward Trajectories, Robert Christopher Owen
Climatological Study Of Transport To The Pico-Nare Site Using Atmospheric Backward Trajectories, Robert Christopher Owen
Theses and Dissertations
This study developed a transport climatology to the PICO-NARE station, in the central North Atlantic Ocean, using a 40-year set of atmospheric back trajectories. The trajectory set was subjected to a cluster analysis in order to group trajectories into six flow patterns, or clusters. An air flow probability analysis was conducted in conjunction with the cluster analysis in order to determine the source regions for flow to the site. Seasonal differences in the flow patterns were found, which included enhanced westerly flow in the winter, decreased westerly flow in the summer, and spring and fall having moderate westerly flow. The …
