Spring 2016 - Dr. Steven Rutledge

Course Syllabus

Course name: Radar Meteorology

Course number: AT741

Instructor: Prof. Steven Rutledge, 307 ATS, 970-491-8283.

Web page: http://radarmet.atmos.colostate.edu/AT741/

Office hours: Tuesday’s, 12:30 – 1:30 PM

Classroom and meeting time: ACRC 212B, 11:00 AM – 12:15 PM, Tuesday and Thursday

Prerequisites: AT652, or permission of instructor

Course goals and Objectives: AT741 is designed to provide a foundational understanding of radar meteorology. Topics presented include microwave scattering theory, Doppler principles, polarimetric radar, dual-wavelength radar, mm-wave radars with applications. The course also provides information on the theory of radar including engineering principles. The objective of the course is to provide the student with a working knowledge of radar meteorology including applications to remote sensing of clouds and precipitation.

Textbook: None

Course readings: As recommended during the semester, also see course web page.

Course calendar: Follows CSU course calendar

Expectations: Regular attendance is strongly recommended. Read the class notes in advance of class.

Statement on academic dishonesty: This course will adhere to the CSU Academic Integrity Policy as found in the General Catalog (http://www.catalog.colostate.edu/FrontPDF/1.6POLICIES1112f.pdf) and the Student Conduct Code (http://www.conflictresolution.colostate.edu/conduct-code). At a minimum, violations will result in a grading penalty in this course and a report to the Office of Conflict Resolution and Student Conduct Services.

Exam schedule: There are no examinations. Course grading is based on homework assignments, projects, and in-class presentations.

Contact hours: About two hours of effort are expected to complete readings and homework assignments outside of class for each hour of class time.

TA information: Brody Fuchs (brfuchs @ atmos.colostate.edu). Office hours are Wednesdays 1-3 pm.

Course grading: The course grade will be based on homework exercises (including some computer-based exercises), in-class presentation/discussion of assigned papers and a final class project (oral presentation).
