Background
Air quality in Bulgaria is a big concern: measurements show that citizens all over the country breathe in air that is considered harmful to health. In this assignment, students are required to use visual analytics approach to reveal spatio-temporal patterns of air quality in Sofia City and to identify issues of concern.
Task 1: Spatio-temporal Analysis of Official Air Quality
Characterize the past and most recent situation with respect to air quality measures in Sofia City. Highlight any trends of possible interest for investigation, including anomalies and how they affect our analysis.
Task 2: Spatio-temporal Analysis of Citizen Science Air Quality Measurements
Using appropriate data visualisation, characterize the sensors’ coverage, performance and operation. Students are required to answer if sensor's well distributed over the entire city? Are they all working properly at all times? And detect any unexpected behaviors of the sensors through analyzing the readings captured.
Task 3: Explore other factors affecting air quality in Sofia City
Urban air pollution is a complex issue with many factors affecting the air quality of a city.
In this third task, students are required to reveal the relationships between factors e.g. local energy sources, meteorology, topography, transboundary pollution and the air quality measure detected in Task 1 and Task 2.
Dataset
Four major data sets in zipped file format are provided for this assignment:
I. Official air quality measurements (EEA Data.zip)
ii. Citizen science air quality measurements (Air Tube.zip): temperature, humidity, pressure and topography
iii. Meteorological measurements (METEO-data.zip): Temperature, Humidity, Wind speed, Pressure, Rainfall, Visibility
iv. Topography data (TOPO-DATA)

I worked on this assignment together with Lee Yeng Ling on the conceptual, implementation and computer-related issues. The Tableau workbook and Wiki writeup are undertaken as individual work.
