A formulation is presented for modeling neutral atmosphere structure in an intermediate height region (70-130 km) between given lower and upper models in temperature, pressure, density and constituent gas concentrations and to maintain continuity in the second derivative of temperature and the other properties with respect to height. The method employs temperature as the prime parameter requiring simultaneously a best fit to available temperature data at the intermediate heights and hydrostatic consistency between the nitrogen partial pressures at 70 and 130 km. The method is well suited to upper and lower models that have analytical representations and is developed as the upper model and for polynomially-generated height-latitude cross-sections in the lower region. Attention is given to comparisons between observed and model temperatures and it is found that mid-latitude data (primarily obtained using the incoherent scatter technique) are on average higher than the models due to the requirement to maintain hydrostatic consistency in nitrogen partial pressures between the 70 km and 130 km values of the given lower and upper models. This discrepancy which at present remains an unresolved problem is discussed in the text. Tables of temperature, pressure, and density are included in the report based on the best fit to available data and simultaneously satisfying the constraints of the upper and lower models. Keywords: Temperature; Mesosphere; Pressure; Lower thermosphere; Density; Model atmospheres. (JHD).

Mathematical modeling of atmospheric composition is a formidable scientific and computational challenge. This comprehensive presentation of the modeling methods used in atmospheric chemistry focuses on both theory and practice, from the fundamental principles behind models, through to their applications in interpreting observations. An encyclopaedic coverage of methods used in atmospheric modeling, including their advantages and disadvantages, makes this a one-stop resource with a large scope. Particular emphasis is given to the mathematical formulation of chemical, radiative, and aerosol processes; advection and turbulent transport; emission and deposition processes; as well as major chapters on model evaluation and inverse modeling. The modeling of atmospheric chemistry is an intrinsically interdisciplinary endeavour, bringing together meteorology, radiative transfer, physical chemistry and biogeochemistry, making the book of value to a broad readership. Introductory chapters and a review of the relevant mathematics make this book instantly accessible to graduate students and researchers in the atmospheric sciences.

This document consists of six chapters from the eBook Understanding Physical Geography: Chapter 5: Atmospheric Structure and Radiation Transfer; Chapter 6: Energy, Temperature and Heat; Chapter 7: Atmospheric Pressure and Wind; Chapter 8: Thunderstorms, Mid-Latitude Cyclones and Hurricanes; Chapter 9: Climatic Regions and Climate Change; and Chapter 10: Human Alteration of the Atmosphere. This eBook was written for students taking introductory Physical Geography taught at a college or university. For the chapters currently available on Google Play presentation slides (Powerpoint and Keynote format) and multiple choice test banks are available for Professors using my eBook in the classroom. Please contact me via email at [email protected] if you would like to have access to these resources. The various chapters of the Google Play version of Understanding Physical Geography are FREE for individual use in a non-classroom environment. This has been done to support life long learning. However, the content of Understanding Physical Geography is NOT FREE for use in college and university courses in countries that have a per capita GDP over $25,000 (US dollars) per year where more than three chapters are being used in the teaching of a course. More specifically, for university and college instructors using this work in such wealthier countries, in a credit-based course where a tuition fee is accessed, students should be instructed to purchase the paid version of this content on Google Play which is organized as one of six Parts (organized chapters). One exception to this request is a situation where a student is experiencing financial hardship. In this case, the student should use the individual chapters which are available from Google Play for free. The cost of these Parts works out to only $0.99 per chapter in USA dollars, a very small fee for my work. When the entire textbook (30 chapters) is finished its cost will be only $29.70 in USA dollars. This is far less expensive than similar textbooks from major academic publishing companies whose eBook are around $50.00 to $90.00. Further, revenue generated from the sale of this academic textbook will provide “the carrot” to entice me to continue working hard creating new and updated content. Thanks in advance to instructors and students who abide by these conditions. IMPORTANT - This Google Play version is best viewed with a computer using Google Chrome, Firefox or Apple Safari browsers.
