Description

Master’s Programme in Atmospheric Sciences is responsible for the course.

Module where the course belongs to:

  • ATM300 Advanced Studies in Atmospheric Sciences
    Compulsory for:
    1. Study Track in Meteorology (if student chooses Meteorologinen kaukokartoitus -course package)

    Optional for:

    1. Study Track in Aerosol Physics
    1. Study Track in Remote Sensing

The course is available to students from other degree programmes.

The following courses should be completed before taking the course

It is also recommended that you complete this course:

For the hands-on application of the learned material attend:

To get a better understanding on how radars are used to study cloud and precipitation processes
  • You will learn how modern weather radars work
  • You will be provided a solid conceptual and mathematical foundation needed to interpret radar measurements
  • You will understand radar observation limitations, i.e. "Doppler dilemma", and how these are mitigated
  • You will be able to convert radar observations to meteorological products, like precipitation rate
  • You will learn how dual-polarization radar observations can be used for hydrometeor classification, attenuation correction and better rainfall estimation
  • On the example of Finnish Meteorological Institute weather radar network, topics related to data quality control will also be discussed

Should be taken at the later stages of studies.

The course will be lectured every other year (even years) in the III period.

  • Introduction to weather radar
  • Types of weather radar measurements
  • Review of EM waves and their propagation through atmosphere
  • Radar hardware
  • Radar equation for point and volume targets
  • Radar signal processing, Doppler measurements
  • Converting radar observations to other meteorological quantities
  • Dual polarization radar observations and the basis for interpretation for various types of storm observations
  • Detailed study of rainfall, QPE and hydrometeor classification with dual-polarization radars
  • Lecture notes
  • V. Bringi and V. Chandrasekar, 2001: Polarimetric Doppler Weather Radar: Principles and Applications
  • R. Doviak and D. Zrnic, 1993: Doppler Radar and Weather Observations

Weekly lectures and exercises (individual work). Total hours 135.

Final grade is based on exercises (30%) and final exam (70%).
