Atmospheric Measurement Techniques for Urban Environments

This course is part of the larger module ENVM1800 "Atmospheric Measurements and Modelling". Students Environmental Engineering within the AEE track follow the larger module ENVM1800.

Other students can follow this course as an elective. Please consult the responsible instructor if you are interested.

The course covers the fundamentals of observational techniques for atmospheric processes with an emphasis on urban environments and high spatial/temporal resolutions.

The following topics will be addressed:

• Importance of collecting data

• Difficulties encountered in urban environments

• General overview of different types of measurement techniques including Doppler and polarimetry

• Basic concepts: wavelength, scattering, absorption, propagation

• Basic definitions and concepts: scale, coverage, temporal/spatial resolution, accuracy, precision etc.

• Rain gauges, Radar, Turbulent flux measurements of momentum, heat and moisture and chemical species, Lidar, Sodar, Radiometers,

• Accuracy, precision, calibration

• Noise measurements in the field, analysis of measured data and filtering

• Quality control, noise, bias, uncertainties and errors.

• Missing values

• Sensor placement, good practices etc.

• Citizen weather stations

• Microwave links, smartphones.

• User engagement and awareness.
