Atmospheric remote sensing 1103-4`MTBA
The course is focused on methods of estimating a variety of atmospheric characteristics using satellite and ground based remote sensing instruments. Topics to be covered include the physical principles of atmospheric remote sensing, aerosol and cloud property retrieval based on scattering and emission, vertical temperature and humidity profile estimates using atmospheric sounders, and retrieval of precipitation with microwave data. The main part of this course includes information about different inversion methods used to retrieve physical and optical properties of the atmosphere.

Assessment criteria
Final assessment will be based on one of the themes proposed by the lecturer. This is generally one of the methods used to process remote sensing data from satellite or surface observation. A list of proposed exercises will be announced in advance. Attendance at lectures and tutorials is strongly encouraged, but is not compulsory.
