GEO 391 (Unique 27935)
GLOBAL LAND ATMOSPHERE INTERACTION DYNAMICS (GLAD)
Goals: To provide an introduction to the role of land in weather and climate systems, and to transition the students from learning a course to doing a research project.
Topics: Basics of terrestrial surface energy, water and carbon balances. Micrometeorology and atmospheric boundary layer. Ecohydrology, biometeorology, hydrometeorology, and hydroclimatology. Theory, modeling, and observations. Spatial scales: point scale (meters) to global. Temporal scales: seconds to centuries. The students will be motivated to learn programming in FORTRAN 90, doing graphics with NCAR Command Language (NCL), formulating science questions, designing numerical experiments, obtaining results using the NCAR Community Land Model (CLM4), visiting tower flux sites to see how radiative fluxes, ground heat fluxes, and turbulent fluxes of CO2, water vapor, and sensible heat are measured, discussing/interpreting the results, writing scientific reports, and making scientific presentations.

Assignments: click here
Basic calculus and physics (M308M and PHY 303K or equivalent courses) and an interest in interdisciplinary processes.
Generally, homework will be due one week from the date when it is given; if it is given on Monday, it will be due next Monday in the beginning of the class. Late homework will not be accepted without a pretty good reason. You are encouraged to work together on your homework if you wish, but make sure you understand what you write down.
Pop-quizzes will be given at random times without prior notice, about every 2 weeks. In these you will be given a question related to the subject matter and/or assigned reading materials to write about or a problem to solve, and about 5 minutes to do it. Please bring loose-leaf paper, a pencil, and a scientific calculator to every class.
There will be no mid-term test and final examination. Participation in class discussions, and raising good questions during lecture are strongly encouraged. Grades will be determined from the following formula:
|Homework/Participation and Basic Programming||40%|
|Bi-weekly 5-minute quiz||15%|
|Land Surface Modeling (CLM4)||15%|
|Literature Review (Due November 5, 2012) [see Elements of Style and A Guide to Write a Paper by G.H. Jirka (1992)]||15%|
|Presentation (final report due November 30, 2012)||15%|
Graduate students need to read and comment on cutting-edge research articles in the literature. In addition, graduate students are expected to demonstrate more skills in quantitative analysis and numerical modeling.
Final Letter Grades: The percent-letter grade relationship will usually be: >90 A, 80-89 B, 70-79 C, 60-69 D, and < 60 Ouch. Your attendance and extra credits will affect your final grades.
