Query: A dense book for a complex topic

Campbell is thorough in his approach to biophysical analysis of multiple environmental scenarios. As a text book, it is fairly dense and provides hints on how to solve specific problems throughout the text. However, finding those hints is sometimes fairly tricky. The equations presented are the latest version of the equations, but some may produce skewed answers in extreme condtions. Living in interior Alaska, some of Campbell's formulas and tables just don't cut it for winter and high-latitude conditions. All in all a solid book though, despite it's initial density and sometimes insufficient clarity.
