Air Quality Forecast
Air pollution is a significant environmental concern, especially in urban areas, where the high levels of nitrogen dioxide and ozone can have a negative impact on human health, the ecosystem and on the overall quality of life. Given these risks, monitoring and forecasting the level of air pollution is an important task in order to allow for timely actions to reduce the harmful effects.
In the Netherlands, cities like Utrecht experience challenges concerning air quality due to urbanization, transportation, and industrial activities. Developing a system that can provide accurate and robust real-time air quality monitoring and reliable forecasts for future pollution levels would allow authorities and residents to take preventive measures and adjust their future activities based on expected air quality. This project focuses on the time-series forecasting of air pollution levels, specifically NO2 and O3 concentrations, for the next three days. This task can be framed as a regression problem, where the goal is to predict continuous values based on historical environmental data. Moreover, it provides infrastructure for real-time prediction, based on recent measurements.
Streamlit Application
Explore the interactive air quality forecast for Utrecht through our Streamlit app on Hugging Face Spaces:
π How to Run the App
To launch the Utrecht Air Quality Monitoring application on a localhost, follow these simple steps:
Navigate to the
streamlit_srcfolder in your terminal where the app files are located.Run the Streamlit application by entering the following command:
streamlit run app.py > [!TIP] > **Alternative Path**: If you are not in the `streamlit_src` folder, provide the full path to `app.py`. For example, from the root directory: > - **Windows**: > ```bash
streamlit run .\streamlit_src\app.py
- **macOS/Linux**: ```bash streamlit run ./streamlit_src/app.py
π How to Run the Scripts
Setting Up
Clone the Repository: Start by cloning the repository to your local machine.
git clone https://github.com/atodorov284/air-quality-forecast.git
cd air-quality-forecast
Set Up Environment:
Make sure all dependencies are installed by running the following requirements.txt file from the repository root:
pip install -r requirements.txt
Running Source Code
First, navigate to the air-quality-forecast folder, which contains the source code for the project:
cd air_quality_forecast
π View the MLFlow Dashboard:
To track experiments, run model_development.py, which will start an MLFlow server on localhost at port 5000.
python model_development.py
If the server does not start automatically, manually run the MLFlow UI using:
mlflow ui --port 5000You might need to grant admin permissions for this process
π Using the parser to retrain the model or make predictions on new data:
Instructions on how to use the retraining protocol or making predictions on new data can be found in the README.md in the air-quality-forecast directory
The retrain datasets need to be under data/retrain and the prediction dataset needs to be under data/inference.
The notebooks in this project were used as scratch for analysis and data merge and do not reflect our thorough methodology (source is under air-quality-forecast). Some extra scripts for the generation of our plots in the report can be found under extra_scripts.
π Viewing the Documentation
The project documentation is generated using Sphinx and can be viewed as HTML files. To access the documentation:
- Navigate to the
_build/html/directory inside thedocsfolder:
cd docs\_build\html\
- Open the
index.htmlfile in your web browser. You can do this by double-clicking the file in your file explorer or using the following command:
open index.html # macOS
xdg-open index.html # Linux
start index.html # Windows
- Alternatively you can navigate to the
index.htmlfile through the file explorer and double click it to run it
