The Upper Atmosphere
Author: Walter DiemingerPublisher: Springer Science & Business Media
ISBN: 3642787177
Category : Science
Languages : en
Pages : 1023
Book Description
Especially due to the increasing environmental problems there is a need to collect as many data as possible in the upper atmosphere. This book serves as a general multidisciplinary guide and introduction for a more effective use of the large amount of now available data from the Earth's atmosphere. It also shows the problems of the use of large amounts of time series data - for basic science as well as for environmental monitoring - and the related information systems. The book is aimed for scientists and students interested in the Earth's atmosphere which is vital for the understanding of environmental changes in the global system Earth.

Book Description
This book provides laser and lidar professionals and students with some basics learning tools in the field of lidar, laser instrumentation, and data analysis. It benefits also ordinary readers who are interesting in remote sensing with laser. The reader will first get an idea about the history of laser and introductory knowledge on the electromagnetic theory. Then the book familiarizes with basic important definitions of terms such as stimulated emission of radiation, population inversion, spontaneous emission, absorption, laser, lidar, maser, radar, water vapor mixing ratio, water vapor density, etc.... . Some basic equations used in lidar and some lidar techniques are also introduced. Water vapor is one of the most important atmospheric variables that play a key role in air quality, global warming, and climate change. Despite its abundance in the atmosphere, and its importance for the climate system, many questions regarding water vapor are presently unresolved. Raman Lidar system has an extraordinary ability to sense accurately water's high temporal and spatial structure in the atmosphere. This book is a review of the electromagnetic theory. It is finally an introduction to lidar techniques for the measurement of Nitrogen, oxygen, and water vapor in the atmosphere.

Book Description
Jens Bosenberg Max-Planck-Institut fur Meteorologie, Bundesstr. 55, D-20146 Hamburg, Germany TESLAS, which stands for Tropospheric Environmental Studies by Laser Sounding, was formed in November 1987 as a subproject of EUROTRAC to enhance the measurement capabilities for vertical profiling of ozone in the troposphere by means of laser remote sensing. For studies of several atmospheric processes related to the formation and redistribution of photo-oxidants there was a clear need for measuring extended time series with appropriate vertical and temporal resolution. These could not be obtained by conventional in situ techniques, at least not with affordable effort, so remote sensing appeared to be the best way to obtain the required information. At the beginning of the subproject, some Differential Absorption Lidar (DIAL) systems for measuring the vertical distribution of ozone already existed, but their use was restricted to very few laboratories and very few measurement campaigns, since the instruments were highly complex, rather unreliable, and required extensive efforts for maintenance and operation by skilled scientists. In addition, the accuracy of these measurements under a variety of meteorological conditions was not really well established. The main tasks within TESLAS therefore were to develop fully the DIAL-methodology for remote sensing of tropospheric ozone, and to develop instruments which are accurate, reliable, easy to operate, and suitable for field deployment or airborne operation.

Book Description
A new mobile lidar was used to obtain data on the variations that occur in the high latitude atmosphere between 20 and 85 km. Data were obtained on 26 nights during the program. Standard meteorological balloon and rocket payloads also measured the density, for comparison with the lidar data. More than a thousand profiles of atmospheric density were obtained with the lidar and 20 meteorological rockets were launched. Comparisons between the lidar data and the meteorological rocket data showed generally good agreement. However, the lidar data from the February period is offset 12-14 percent from the rocket data. The March and April data, including 14 sets of overlapping data, generally agree to within 3 percent. Keywords: Lidar; Atmospheric density; Middle atmosphere; Atmospheric variations; High latitude atmosphere.
Differential Absorption Lidars for Remote Sensing of Atmospheric Pressure and Temperature Profiles

Book Description
A near infrared differential absorption lidar technique is developed using atmospheric oxygen as a tracer for high resolution vertical profiles of pressure and temperature with high accuracy. Solid-state tunable lasers and high-resolution spectrum analyzers are developed to carry out ground-based and airborne measurement demonstrations and results of the measurements presented. Numerical error analysis of high-altitude airborne and spaceborne experiments is carried out, and system concepts developed for their implementation. Korb, C.
