Analyze air quality data with Python, focusing on AQI, PM2.5, and PM10 from EPA sensors. Understand health, environmental impacts, and policy drivers like emission reductions and the Clean Air Act.
Set up a Google Colab notebook, distinguish code cells from text cells, and install essential Python libraries, pandas, numpy, matplotlib, and seaborn, for environmental data analysis.
Learn to download EPA air quality data, upload a csv to Google Colab, and preprocess with pandas to inspect PM2.5 data, handle missing values, and convert dates.
Graph air quality index over time by plotting daily AQI value vs date from your data frame, using matplotlib/seaborn and a tight layout.
Explore plotting AQI against daily mean PM 2.5 concentration using matplotlib and seaborn, with grid styles and labeled axes, then quantify their linear correlation using linear regression and R squared.
Use linear regression to evaluate the correlation between AQI and PM 2.5, fit and predict with a sklearn model, compute r-squared, and plot the regression line on a scatter plot.
Compare California's PM 2.5 and AQI data across 2024 and 2000 using Python, computing monthly average AQI and plotting year-over-year trends to explain changes.
Graph NO2 data from EPA outdoor air quality for 2024 in Massachusetts by loading a CSV, converting date to a date time object, and plotting max NO2 concentration with seaborn.
Interested in air quality, programming, or data analysis? Then this course is for you!
In this course, you will learn how to analyze and visualize air quality data using Python in the Google Colab IDE. We'll explore how air quality has changed over time by comparing key indicators like the Air Quality Index (AQI), PM2.5, and NO2 levels across different years and cities. Using real-life data collected by the Environmental Protection Agency (EPA), we'll cover how to handle missing values, prepare data for analysis, and create informative visualizations. We'll start by importing and cleaning environmental data, ensuring it is ready for analysis. Then, you'll learn how to perform exploratory data analysis (EDA) to identify trends and seasonal patterns. We will graph data and look into any observations we may notice. We'll delve into advanced techniques like linear regression to examine relationships between pollutants and predict AQI values. Our visualization journey will include plotting data from multiple regions and comparing air quality across different years. You'll learn to create clear, compelling graphs using libraries such as `matplotlib` and `seaborn`. By the end of this course, you'll have the skills to analyze environmental data, uncover insights, and communicate findings effectively. No prior programming experience is needed.
