Radiative Heat Exchange in the Atmosphere analyzes the concerns in thermal radiation and the radiation balance of the earth's surface and of the atmosphere. The text first covers the basic definitions and concepts, and then proceeds to discussing the development of basic theories of actinometric measurements of thermal radiation fluxes. Next, the selection deals with the absorption of long-wave radiation in the atmosphere. In the fourth chapter, the title covers the solution of the problem of radiative heat transfer in the atmosphere. Chapter 5 details the examination of the approximate methods of calculation of thermal radiation fluxes, while Chapter 6 discusses the problem of the atmosphere and the net radiation at the ground. The seventh chapter tackles the radiation balance, and the last chapter covers the features of the methods and the results of calculating temperature changes caused by radiation. The book will be of great use to researchers and practitioners of astrophysics and meteorology. Ecologists and other environmental scientist will also benefit from the text.

Thermal Radiation: An Introduction is a complete textbook for a one-semester introductory graduate course on radiative energy transfer. It bridges the gap between a basic introduction and comprehensive coverage of thermal radiation, focusing on insight into radiative transfer as practiced by engineers. Covering radiative transfer among surfaces, with an introduction to the effects of participating media between surfaces, the book includes surface and medium property characteristics and solutions to the radiative transfer equation in simple geometries. • Tailored and organized specifically to suit a one-semester graduate course in radiative heat transfer. • Emphasis is placed on insight into radiative transfer as practiced by engineers. • Discusses how radiation is incorporated into finite element analysis (FEA) codes. The textbook is intended for instructors and graduate students in a first-year course on radiative heat transfer or advanced heat transfer. Supplementary resources for students and instructors are available online.

Design studies on the reuseable surface insulation (RSI) systems for the Space Shuttle require accurate data on the thermal conductivity of ceramic-fiber insulations. Well-established laboratory techniques, such as the guarded hot plate experiment, are available for such measurements; however, caution must be exercised in applying laboratory data to widely different re-entry thermal environments. The heat-transfer associated with infrared radiation transmitted through the fibrous materials must be considered. Various analytical models have been developed to account for this radiant heat transfer, but their verification has often been incomplete. A new approach has now been applied in which infrared transmission measurements were made with an optical system that collected all the scattered radiation transmitted through the back surface of fibrous samples. Experimental data were analyzed using a "two-flux" model for the radiation scattered and absorbed in the materials and excellent correlation was obtained between theory and experiment. To account for the wavelength dependence of the scattering cross-sections of many materials, a "four-flux" model was developed. This model was used to compute the contribution of the radiation transmission to the total thermal conductivity of samples measured on the guarded hot plate equipment. The contribution was shown to be as high as 75 percent of the total conductivity at temperatures above 1000 K.
