Course Objective

After taking this course you should have a working knowledge of the principles of atmospheric chemistry and some in-depth knowledge on some areas of current interest. A good gauge of this accomplishment is for you to be able to understand the current research literature, or atmospheric chemistry seminars in Boulder (CU, NOAA, and NCAR).

 

Boulder is one (perhaps ÒtheÓ) of the worldÕs capitals for atmospheric chemistry. If you are doing research in this area, make an extra effort to take advantage of the fact that you are here to attend seminars and get to know local and out-of-town atmospheric scientists.

 

Course prerequisites

The course prerequisites are undergraduate chemistry, physics and calculus.  You are responsible for supplemental work that you may need to catch up in any of the prerequisite areas.

Introduction to Atmospheric Chemistry

This class will NOT follow an exact textbook.  We will use textbooks to get background information and addition details for each section.  Much of the material can be found in either Finlayson-Pitts or Jacob.  However, the photochemistry portion of the class is only covered in the Finlayson-Pitts textbook.  You have the option to use both texts, or just choose one.  If you do not buy Finlayson-Pitts, you may need to borrow a copy to get additional information on photochemistry.  The Jacob textbook is available online in pdf format for free.  Note that the Finlayson-Pitts book, though expensive, is an excellent reference book to own if you are continuing in atmospheric chemistry.

Course Grading Policy

The grade will be determined as the weighed average of:

 

Late homework will not be graded unless we have agreed to an extension ahead of time. If they are graded, the grade will be multiplied by 0.75 to discourage lateness. Only exceptions are cases of personal (not academic) hardship.

Homework and Exam Legibility

It is often a significant problem to ÒdecodeÓ homework and exams if the writing is too small or messy, or if they are poorly organized. We may take points out for poor legibility at our discretion.  The current homework will be posted on the course page in Word to save you the typing, should you decide to type your homework.

Please list the units of all results (SI units if possible).

 

Reading Assignments

Every lecture will have a reading assignment, as indicated in the course schedule below. Since we will be following the texts only in a general sense, reading the whole assignment before the lecture would be overkill. However you should look the material briefly before class, and if you are not having difficulty, you should read the material in more detail after class.

 

Structure of Student Presentations

Students will be required to present one journal paper on an atmospheric chemistry topic to the class. The purpose is to gain familiarity with current topics in the field as well as to understand and practice scientific presentation skills. Students should begin considering articles for presentation as soon as possible, preferably selecting one related to proposed research, and check with the instructor for their suitability no later than 2 weeks prior to presentation.  Questions from the presentations will be included on the Final Exam.  Presentations will be AGU style, 12 minutes long, with 3 minutes for discussion.  Presentations will be made throughout the semester.

 

Class Participation

Students are required to attend class and participate in class discussions.  We will be using ÒclickersÓ to aid in class participation.  Clickers can be purchased from the CU bookstore and are required for this class.  You will be asked questions daily in class and will click in your response.  You will not be penalized for incorrect answers.  You will, however, be awarded ÒparticipationÓ points simply by clicking in your response.  This will account for 15% of your class grade.  These are the same clickers as used last year so you may borrow a clicker from a previous student.  However, you may not share a clicker with another student in the same class.

Changes to the Course during the Semester

As with life, this syllabus is subject to change. I may make some changes to the course during the semester as appropriate, including to lectures, assignments, presentations, and exams.

Religious observances

 

Campus policy regarding religious observances requires that faculty make every
effort to deal reasonably and fairly with all students who, because of
religious obligations, have conflicts with scheduled exams, assignments or
required attendance.  In this class, please let me know if you have any conflicts and we will make arrangements.  See full details at http://www.colorado.edu/policies/fac_relig.html

 

Classroom behavior policy

 

Students and faculty each have responsibility for maintaining an appropriate

important with respect to individuals and topics dealing with differences of
race, color, culture, religion, creed, politics, veteran's status, sexual
orientation, gender, gender identity and gender expression, age, disability,
and nationalities.  Class rosters are provided to the instructor with the
student's legal name. I will gladly honor your request to address you by an
alternate name or gender pronoun. Please advise me of this preference early in
the semester so that I may make appropriate changes to my records.  See policies at
http://www.colorado.edu/policies/classbehavior.html   and at
