Photoabsorption And Photoionization Cross Sections Of O O2 And N2 For Photoelectron Production Calculations A Compilation Of Recent Laboratory Measurements

Energy Research Abstracts

Atmospheric Ultraviolet Remote Sensing

This book is an introduction to the use of the ultraviolet for remote sensing of the Earth's atmosphere. It covers the Earth's UV radiative environment, experimental techniques, and current applications. it is my intention to provide the information needed to "make a first approximation" concerning the use of the ultraviolet and to provide access through the literature for a more thorough study.* Contains recent UV applications not previously available in book form such as ozone, auroral images, and ionospheric sensing* Features broad coverage of fundamentals of atmospheric geophysics with values for fluxes, cross-sections, and radiances* Covers techniques that illustrate principles of measurements with typical values* Contains numerous references to original literature

Photoabsorption and Photoionization Cross Sections of O, O2, and N2 for Photoelectron Production Calculations: A Compilation of Recent Laboratory Measurements

REcent laboratory measurements of photoionization cross section s and ion state branching ratios for atomic oxygen, molecular nitrogen and molecular oxygen are combined with theoretical cross sections for soft x-ray absorption and tabulated for use in atmospheric photoionization calculations. The most important changes from earlier compilations for aeronomical calculations is a factor of approximately two reduction in the absorption and ionization cross section of atomic oxygen between 100 angstroms and 300 angstroms, and a detailed treatment of partial cross sections for the dissociating state of N2 and O2. The results are tabulated on the wavelength scale of the Atmospheric Explorer solar reference spectrum SC 21REFW (Hinteregger et al., 1981).
