Course grades including the final exam are posted under the Grades link. Please check over your grade and let me know if you believe there is a mistake. I will wait until Friday morning to officially submit the grades. I wish you all a nice winter break.

Monday, December 7:
Course grades without the final exam are posted under the Grades link. Explanation of columns on the gradesheet. HWave is your homework average, which is the sum of the class registration and the four homeworks divided by 4. This is 20% of your weighted class average. Another 20% is based on the research paper plus optional topic. There is also 20% weight for each of the three in-class exams. Class Average is your weighted class average, with 20% homework average, 20% topic plus research paper, 20% exam 1, 20% exam 2, and 20% exam 3. The letter grade scale is based on your weighted class average, A (88%), B (76%), C(63%), D(50%) and E(<50%). This is the letter grade you will get in the class if you do not take the final exam. The column "To Raise Grade" tells you what you need to score on the final exam to raise your letter grade one letter higher than you have without the final exam. The final exam is completely optional. Please scroll down to the course information below to read how taking the final exam will affect your class average. The letter grade scale remains the same for those who take the final exam.

If you are definitely not taking the final exam, then you do not need to come to class tomorrow, unless you would like to pick up graded material. If you have any questions about the grading or are considering taking the final exam, then you should come to class tomorrow. Please bring your previously graded in-class exams 1 and 2 with you to class. I will talk about how to prepare for the final exam and do a brief review of some of the topics covered during the semester.

Class Notes / Important Dates:

There is no textbook for this course. Lectures will be based on the reading material posted under the Lectures Link and additional material that will be distributed during lectrues throughout the semester. I expect that each student read over the relevant reading material before the lecture is presented in class. This is important because the you will be famaliar with what I discuss in lecture and better able to understand it.

Important dates, such as homework deadlines, exam dates, etc., will be posted in the class calendar.

Academic Integrity:

The University of Arizona's Code of Academic Integrity, Code of Conduct, and Student Code of Conduct will be strictly followed. All students are responsible for knowing the codes and abiding by them. Please see Academic Integrity Policies for University of Arizona Students.

Accessibility and Accomodations:

It is the University's goal that learning experiences be as accessible as possible. If you anticipate or experience physical or academic barriers based on disability or pregnency, please let me know immediately so that we can discuss options. You are also welcome to contact Disability Resources (520-621-3268) to establish reasonable accommodations.


Class Grades will be posted under the grades link as a spreadsheet. Currently the link points to the gradesheet from a previous class. You will will choose a class ID that will be known only to you so that you can see your grades. There is a Class Registration form posted under the homework link. You will be given 10 extra credit points on your semester homework score for submitting the form by the due date. If you do not submit a form, there will be a blank space in the Class ID column for your grade row.

Please see the course syllabus for more detail about assignments and grading.


Four homework assignments will be given periodically during the semester. The first two will be brief problem sets go with the exam 1 and exam 2 material. Sometime in late October, a 500 mb forecasting project will be assigned. Lastly, global warming opinion essay will be due near the end of the semester. The sum total of all homework accounts for 20% of your final grade. Individual homework assignments may not be weighted equally in determining your overall class homework grade.

Your homework assignments will be graded on the quality and clarity of your English as well as their content. No cheating, fabrication, facilitating academic dishonesty, or plagiarism will be tolerated (see University of Arizona Code of Academic Integrity). The research paper and perhaps some of the homework assignments will be filtered through Turnitin. Homework assignments turned in late will incur a grade reduction of 10% per day.

All homework assignments will be available on the class web page. You will be notified in class and with an announcement on the class homepage when homework assignments are posted. You will be given plenty of time to complete assignments.

Research Paper:

A research paper on the subject of the United States adopting an emission control policy will be required for each student. Information about the paper is available under the homework link . I will discuss the research paper in class on Tuesday, September 1. Please read over the assignment sometime before coming to class on September 1.

The research paper will account for 20% of your final class grade. It is due on or before October 15, which is approximately the midway point in the semester. I strongly suggest that you begin to work on your paper long before the due date. The paper accounts for a significant portion of your final grade. As an incentive to begin early, there is an optional assignment, which is due by September 9, in which I ask you to specify your topic and provide a preliminary list of references. You can earn up to 5% extra credit on your research paper for this assignment. Information is available under the homework link .


There will be 3 in-class exams and a final exam. Exam grades account for 60% of your final grade. Each in-class exam will account for 20% of your final grade. The exams will consist of a mixture of multiple choice and short answer questions. The in-class exams are not comprehensive in that the questions concentrate on material covered since the last exam. However, it is expected that you are familiar with some of the basic concepts covered early in the semester.

Questions from previous exams will be made available on the class web pages.

The final exam is optional. If you decide to take it, the final exam grade replaces the lowest of the grades of your previous exams (even if it is lower). Thus, if you do poorly on one exam or miss one exam, you can make for it up by taking the final. Your final exam score will also replace half of your second lowest exam score (only if higher than your second lowest exam score). Therefore, if you take the final exam it will count for at least 20% of your final grade (by replacing your lowest exam score) and 30% of your final grade (if you score higher than your second lowest exam score). The final exam is comprehensive in that it covers all of the material presented during the semester.

Final exam is Tuesday, December 15 from 8:00 - 10:00 in the regular classroom, Koeffler 218.

Exam Policy:

You are expected to study and understand material covered in class during lecture as well as to read the relevant material from the class notes. Exam questions will be taken from both the in-class lectures and the reading material included in the class web pages.

Please contact the instructor (preferrably via e-mail) as soon as possible if for an unexpected reason you are unable to be in class for an exam. A make-up exam will be arranged with sufficient proof. No make-up exam will be given unless you notify the instructor BEFORE missing the exam in class. In general, I would prefer make-up exams to be taken before the exam is given in class.

Grade Scale:

Your final grade will be curved and therefore depends on everybody else's grades. However, the grade scale will not be any more difficult than A(90%); B(80%); C(70%); D(60%).
