Description

Industry, traffic and (forest) fires emit nitrogen dioxide (NO2). This emitted NO2 forms
plumes that are transported by the wind. The TROPOspheric Monitoring Instrument (TROPOMI) on Sentinel-2P is able to detect these plumes. The NO2 is further involved in chemical reactions in the atmosphere. In this topic you will visualize the paths of NO2 from the sources using the TROPOMI NO2 product. Different aspects of the problem can be addressed depending on the interest of the student and the open questions at the time of topic selection, including: study cases of the Australian Eucalyptus fires, quantifying sources using NO2 concentrations and wind profile data, or detailed mapping of NO2 concentrations in specific areas, such as areas with lots of fires or industrial areas.

Objectives and Methodology

The objective is to analyse satellite NO2 data. The specific objectives will depend on the interest of the student and the open questions at the time of topic selection. It can include:
- Methodology testing to identify and quantify sources of NO2
- Mapping of distribution of NO2
- Quantifying concentrations after events such as fires.
The methodology includes accessing, processing, visualization and interpretation of TROPOMI data of NO2 and ECMWF meteorological data.
