Abstract

The lecture will introduce the student to the thematic of solar ultraviolet radiation and its effects on the atmosphere and the biosphere, as well as the determination of atmospheric trace gases such as ozone and aerosols. In addition, the lecture will cover the modeling and the measurement of solar ultraviolet radiation.

Objective

- Effects of solar UV radiation on the Atmosphere, Humans, and the biosphere in general. - Measurements of solar UV radiation (ground-based, satellite-based). - Introduction to radiative transfer modelling, specifically for UV radiation. - Methods to retrieve atmospheric constituents such as atmospheric ozone and aerosols from solar radiation measurements. - Long-term trends and past, present and future changes in solar UV radiation and its relationship to Climate change.

Content

The Lecture is composed of the following chapters: 1) Introduction and Motivation on the impact of solar UV radiation on the atmosphere, humans, and the biosphere in general. 2) Historical review of the scientific research. 3) Variability of solar UV radiation from a solar perspective (solar cycle, solar UV variability, impact on the higher atmosphere). 4) Understanding the variability of ground-based solar UV radiation with respect to the parameters influencing the transfer of solar UV radiation through the atmosphere. 5) Instruments to measure solar UV radiation 6) Introduction to radiative transfer modeling, with emphasis on solar UV radiation. 7) Retrieval of atmospheric trace gases from solar radiation measurements. Specific examples for retrieving atmospheric ozone, aerosols, and surface albedo.

Examination

Type
graded semester performance
Two to three exercises will be distributed during the period of the lecture. The exercises are to be done individually by each student and submitted electronically to the supervisor. The correction will take place during the following lecture course.The use of a computing software such as Matlab, Python, R would be advantageous.
