Objectives

To introduce the principles of weather and climate at the micro-, local-, and meso- scales. To learn of the processes associated with the transfer of heat, mass and momentum and the resulting climates near the earth's surface. To become familiar with plotting and analysis of meteorological data using computers. To learn to program and connect a variety of meteorological instruments to data loggers and set up an electronic weather station. To be introduced to the essentials of air pollution meteorology and dispersion modelling.

Evaluation

There will be a mid-term exam, a final exam, and eight marked labs. The mid-term exam is scheduled for the second class the week of October 8 during the lecture period. The final exam will occur sometime during the December exam period, so no travel or employment plans should be made during this time. The lab marks will not all be weighted equally - the weighting is indicated next to the lab name in the topic list. Lab assignments handed in late will have marks deducted at a rate of 20% per day, except for medical or other extraordinary circumstances. In any case, the instructor must be notified of late assignments prior to the due date. Missed exams cannot be made up except on documented grounds and notification prior to exam date. Plagiarism and other forms of cheating will not be tolerated and will be strictly dealt with according to university policy (see the ``Academic Offenses'' section of the UNBC Calendar).

Laboratory Assignments 45%
Mid term Exam 20%
Final Exam 35%
Total 100%
