AbstractPhysical, technical, and theoretical basics for measuring physical quantities in the atmosphere. Considerations related to the planning of observation campaigns and to data evaluation.
ObjectiveBecome sensitive for specific problems when making measurements in the atmosphere under severe environmental conditions. Know the different methods and techniques for observing a specific atmospheric parameter. Find the optimal observation strategy in terms of choice of instrument, frequency of observation, accuracy, etc.
ContentProblems related to time series analysis, sampling theorem, time constant and sampling rate. Theoretical analysis of different sensors for temperature, humidity, wind, and pressure. Discussion of effects disturbing the instruments. Principles of active and passive remote sensing. Measuring turbulent fluxes (e.g. heatflux) using eddy-correlation technique. Discussion of technical realizations of complex observing systems (radiosondes, automatic weather stations, radar, wind profilers). Demonstration of instruments.

Prerequisites / NoticeThe lecture focuses on physical atmospheric parameters while lecture 701-0234-00 concentrates on the chemical quantities. The lectures are complementary, together they provide the instrumental basics for the lab courses 701-0460-00 and 701-1230-00. Contact hours of the lab courses are such that the lectures can be attended (which is recommended).

Prerequisites: Atmosphärenphysik I und II
