Course announcement:

Atmospheric observations of aerosols, clouds and trace gases (ATM-319)


Organized as virtual training school on May 3rd-10th, 2021

Course content:

This is an advanced course on atmospheric observations of aerosols, clouds, and trace gases. The topics covered in the course include in-situ measurements and ground-based remote sensing techniques of aerosols, reactive trace gases, and clouds.

The students are expected to learn to understand the basic principles behind the measurement methods, to know the most important instrumentation including their advantages and limitations, and to use openly available data to answer their own research questions. We will also address issues related to open data, data management, data quality, and integration of different observations.

Teaching methods:

The course consists of a pre-assignment (to be completed before the course), lectures and group work during the intensive period and project work, which should be handed in after the course. Attendance during the intensive period (3rd to 10th May, ca. 9-17 CET daily) is mandatory. The lectures are given via Zoom.

Master and doctoral students will obtain 5 ECTS after successful participation and completing all assignments.

Target group and prerequisites:

The course is intended to master students, doctoral students, young scientists (e.g. post docs), and personnel from aerosol measuring stations and research institutes involved in ACTRIS, CRAICC, GAW, GUAN, and EMEP.

Good English understanding and speaking skills, as well as basic knowledge about atmospheric science, are required. The students should have at least basic skills in data analysis using a program of their liking (e.g. Matlab, Python).

The number of participants is limited. In case there are too many applications, students will be selected based on their reason to take the course, their study background, and the order of registration.


The course is coordinated by Associate Prof. Katrianne Lehtipalo (University of Helsinki, INAR and Finnish Meteorological Institute). Lectures are given by various guest experts.

More information and a detailed program will be available later.
