An

Introductory Survey, 2
nd

Edition
, by Wallace and
Hobbs


This is a basic Atmospheric Science text that provides a fundamental overview of
atmospheric physics and chemistry, and includes both descriptive and quantitative
approaches to the subject. To cove
r all material in the text would take two or more
semesters. We will address only a subset of topics and skip some of the details even
in the topics that we cover. The text will be supplemented with lecture notes that
will some times follow the text, and

some times deviate. There will be some
jumping around between different chapters, but I will attempt to link the lecture
notes to specific pages in the book.


The first third of the course will cover the composition and structure of the
atmosphere, radia
tion and energy balance, and global warming. Also the first third
of the course will include a good look at atmospheric chemistry including topical
issues such as the ozone hole and air pollution. This part of the course will have
both quantitative and d
escriptive elements. The math will include differential and
integral calculus. The remaining two
-
thirds of the course will be an introduction to
the thermodynamics and dynamics of the atmosphere that explore quantitatively
the forces that initiate atmosp
heric motion and create our weather. I hope to have
time during the second 2/3 of the course to pay attention to daily weather
conditions and forecasts, with the goal of linking the topics under study with the
weather forecasts in the media and what we se
e outside.


Grading: Weekly homework assignments: 45%


2 midterms: each 15%


Comprehensive final: 25%


Communication will be in class or via email. I will not be using blackboard. Feel
free to email me or call
anytime.


Homework assignments may be done individually or cooperatively. If working
cooperatively, the final write up of any assignment must be in your own words and
you must give credit when taking ideas from others. Using someone’s ideas without
citin
g the source of those ideas is dishonest. The three exams must be your own
individual effort with no help from others.
