  4. Course Description Introduction to the science of weather processes and climate change: atmospheric structure and composition, energy balance, clouds and precipitation, wind systems, fronts, cyclones, weather forecasting, thunderstorms, lightning, hurricanes, ozone hole, air pollution, global warming and optical phenomena. Lecture 1-Nats 101

  5. Course Description Emphasis will be given to phenomena that have strong impacts on human activities. The fundamental importance of physics, chemistry and mathematics will be noted. Atmospheric Sciences  Applied Physics Lecture 1-Nats 101

  6. Attendance Policy Attendance is mandatory, and I reserve the right to tally it throughout the term. After three unexcused absences prior to week 9, I will submit to the Office of Curriculum and Registration an administrative drop from the course and assign a grade in accordance with UA policy. Lecture 1-Nats 101

  7. Student Behavior UA Code of Academic Integrity, Code of Conduct and Student Code of Conduct are enforced in this course. Every student is responsible for learning these codes and abiding by them. Students can submit complaints online at Lecture 1-Nats 101

  8. Grading Policy Final grade will be based on scores from closed book/closed notes quizzes and final exam. Quizzes will consist of multiple choice questions and short answer questions. Quizzes will cover new material presented through the end of the previous lecture day. Extra credit questions given on some quizzes. Extra credit impromptu “pop” quizzes given. Lecture 1-Nats 101

  9. Grading Policy • There will be seven quizzes during the term. Dates for the quizzes areSep 6, Sep 20, Oct 4, Oct 18, Nov 1, Nov 17, Dec 1.No Exceptions • Students who arrive late on quiz days will be not allowed to take the quiz after the first student turns in her/his quiz.No Exceptions • The lowest score among the seven quizzes will be excluded from the course grade. Therefore, no make-up quizzes. Lecture 1-Nats 101

  10. Grading Policy • If your final exam score exceeds the average of your 6 best quizzes, the quizzes will comprise 60% of your term grade and the final 40%. Otherwise, the quizzes will comprise 75% of your term grade and the final 25%. • CARROT: If your average is 90% or higher on all 7 quizzes, you will earn an exemption from the final and will receive an "A'' for the course. • No Extra Credit Projects. No Exceptions. So Plan Accordingly! Lecture 1-Nats 101

  11. Final Examination Section 4 (9:00 am MWF): SS 100 Dec 15, 8:00 am - 10:00 pm No Exceptions per UA Policy • The final will consist of 60 multiple choice questions and short answer questions. • At least 30, but no more than 40 questions, will be taken verbatim from the old quizzes. Lecture 1-Nats 101

  12. Course Grading • Course Grading Scale A 90% or higher B 80.0-89.99% C 65.0-79.99% D 55.0-64.99% E < 55.0% Lecture 1-Nats 101

  13. Expectations Every student is expected to: • Complete all of the assigned reading before the lecture, unless you hear otherwise. • Devote a minimum of 2 hours outside of class studying, reading, etc. for every hour of classroom lecture. Unit Credit Definition • Attend class daily, arrive on time, leave when class is dismissed (courtesy to peer students). Lecture 1-Nats 101

  14. The Golden Rule Instructor and students all show: Mutual Respect! What exemplifies respectful behavior? No talking No electronics Arriving on time Remaining seated Lecture 1-Nats 101

  15. Literacy Requirements Although the writing requirement for this course is negligible, there is a science literacy requirement. This means that we: • Use scientific notation for writing numbers (especially rather large or small ones). • Specify units of physical quantities (e.g. meters for elevation, etc.). • Attempt to quantify physical relationships.

  23. Importance of Atmosphere • Point 1- Offers Protection Consider surface temperatures Without atmosphere? 0oF average, large day-night swings Similar to the Moon’s Climate With atmosphere… 60oF average, moderate diurnal swings Lecture 1-Nats 101

  24. Importance of Atmosphere • Point 2 - Offers Protection Consider Surface Radiation Shields against harmful UV radiation Lecture 1-Nats 101

  25. Importance of Atmosphere • Consider Survival Time Without Food  few weeks Without Water  few days Without Air  few minutes Lecture 1-Nats 101

  26. Atmosphere Sun Earth 13,000 km Space To Understand the Atmosphere Examine its interfaces with land/ocean with space Is a very thin skin 99% below 50 km (31 miles) 50% below 5.5 km (3.4 miles) Atmosphere Picture Energy Flow Solar Input = Output to Space Lecture 1-Nats 101
