Download or read book Determination of Ionospheric Electron Density Profiles from Satellite UV Emission Measurements FY 84 written by R. E. Daniell and published by . This book was released on 1985 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The possible use of satellite ultraviolet measurements to deduce the ionospheric electron density profile (EDP) on a global basis is discussed. A system concept is considered and analyzed which (a) develops and installs a UV sensor on the DMSP satellite and develops an associated automatic data processing (software) system, (b) utilities optical data together with DMSP electron density and temperature data to deduce the near real-time EDP near the satellite orbital plane, and (c) transmits this EDP data to be used together with ground-based ionosonde data and GPS total electron content data to specify the global EDP for systems users. The ionosonde and total electron content data would increase the EDP data base generated by the UV data and refine the UV based EDP where coincident data existed. This report considers (a) the daytime low to midlatitude ionosphere from 90 to 1000 km, (b) the nighttime midlatitude from about 250 km to 1000km, and (c) the auroral E layer from 90 to about 200 km for undisturbed conditions. The spatial resolution for the daytime and nighttime EDP is at least one vertical profile for each square 500 km on a side and for the auroral E layer at least one vertical profile for each square 50km on a side. Other ionospheric regions were not considered because of frequent occurrence of irregularities or highly variable transport conditions.

Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book Role of Chemical Effects in Daytime High Latitude Trough Formation written by Christopher Sherman and published by . This book was released on 1989 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of enhanced chemical reaction rates in the formation of the daytime F-region trough is examined. A simple convection model is used to estimate the maximum likely elevation of effective temperature for the ion reaction O+ + N2 yields NO(+)+ N. Under extreme conditions the effective temperature can reach 4000 k resulting in a 30-fold increase in the reaction rate. However, the resulting reduction in F-region electron density is only a factor of 4. Under more usual conditions, the reduction is less than a factor of 2. The actual density reduction factor in the daytime trough is observed to vary between 3 and 10 under normal conditions. Therefore, we conclude that under most circumstances, convection-enhanced chemistry contributes very little to the formation of the daytime trough.
