Text: Specially prepared laboratory guides, instrument manuals, and current scientific literature. Extensive use will be made of Instructor's Handbook on Meteorological Instrumentation, F. Brock, Ed.,(NCAR Tech. Note NCAR/TN-327+1A) 1984. Handbook of Meteorology Finlayson-Pitts and Pitts, Atmospheric Chemistry, 2002. Excellent WMO site http://www.wmo.int/pages/prog/www/IMOP/CIMO-Guide.html Grading: Best seven (for undergraduates best six) of nine laboratory reports (70%) lab notebook (10%) and a final exam (20%). The AOSC634 final will include additional, more challenging questions. Lab reports will be graded on a 10-point basis (>9 = A; >8 = B; >7 = C) the average of your best reports will be counted.
