Knowledge Expectations for METR 3613
Meteorological Measurement Systems
Purpose: This document describes the principal concepts, technical skills, and fundamental
understanding that all students are expected to possess upon completing METR 3613, Meteorological
Measurement Systems. Individual instructors may deviate somewhat from the specific topics and order
Pre-requisites: Grade of C or better in METR 2024 (or 2413), MATH 2443, PHYS 2524.
Students should have a basic understanding of electronics and physics of the atmosphere prior to
starting this course.
Goal of the Course: This course introduces the physical principles of meteorological instruments,
discusses static and dynamic sensor performance, and explores the concepts of meteorological
measurement systems. Through lectures and laboratory exercises, students will learn to work with
meteorological instruments, and to identify sensor limitations and major error sources.
Furthermore, basic procedures of data analysis will be discussed and applied to different types of
