Observation of ozone concentration during the solar eclipse

Abstract We report the results of measurements of ozone concentrations during the solar eclipse of 11 Ž . August 1999. The experiment was performed in Warsaw Poland and its surroundings. The temporal evolution of ozone concentration was measured using the differential absorption lidar Ž . DIAL and it was compared with results obtained by several monitoring stations measuring with other methods. In almost all cases, a drop in the ozone concentration was observed during the eclipse. Experimental data was compared with calculations done using a simple model based on NO -O chemical kinetics. q 2001 Elsevier Science B.V. All rights reserved

Why peace?: stories of activism and altruism in Indiana : [an honors thesis (HONRS 499)]

Graduating from college is an enormous transition, and once made it can be especially difficult to integrate past hobbies and interests into daily life. This includes the work of an activist. After finding myself approaching this transition I had questions regarding activism and the commitment, passion, and motivation involved. Psychology has many theories on aggression and war; however, some psychologists have, instead, focused on the altruistic individual or the committed activist. I explored this aspect of human nature by interviewing six individuals, all located in Indiana, who actively work for social or political change. This project broadens the meaning of the word activism to include any type of action that may improve the life of another or help a community to grow. The interviews are presented in the form of film with an introduction and conclusion narrated by David Chudzynski. The stories shared by these six individuals offer encouragement and advice for those hoping to incorporate activism into life after college.Thesis (B.?.)Honors Colleg

SMILES observations of mesospheric ozone during the solar eclipse

日食を利用して太陽光が大気中のオゾンへ与える影響を調査. 京都大学プレスリリース. 2015-06-16.The Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) successfully observed vertical distributions of ozone (O[3]) concentration in the middle atmosphere during the annular solar eclipse that occurred on 15 January 2010. In the mesosphere, where the photochemical lifetime of O[3] is relatively short (approximately 100 s), altitude-dependent changes in O[3] concentration under reduced solar radiation and their temporal variations were clearly observed as a function of the eclipse obscuration. This study reports the vertical distributions of mesospheric O[3] during a solar eclipse event and analyzes theoretically the eclipse-induced changes. We show that simple analytical expressions for O[3] concentration, which assume that O[3] and O are in a photochemically steady state, can be used to describe the O[3] concentration under reduced solar radiation. The SMILES data obtained during the eclipse provide a unique opportunity to test our current understanding of mesospheric O[3] photochemistry
