citywise-pm25-forecast

An AI-powered Streamlit web application to forecast PM2.5 air pollution levels for any Indian city using historical environmental data.

🚀 Features

  • 📊 City-wise PM2.5 concentration prediction for next 3 months
  • 🧠 Trained on XGBoost Regression Model
  • 🏙️ Built using Indian air quality & meteorological datasets
  • 📉 Auto-reshaping of historical wide-format data to time-series format
  • 📦 Real-time visualization & download of forecast data
  • 💡 Streamlit UI for easy use and deployment

📌 How It Works

  1. Historical air quality data is loaded, cleaned, and reshaped (wide → long format)
  2. Features like year, month, SO2, NO2, PM10, and previous PM2.5 values are used
  3. XGBoost Regression is trained to forecast PM2.5 for the next 3 months
  4. User selects city in Streamlit UI and gets predictions & plots

🧪 Model Details

  • Model: XGBoostRegressor
  • Target: PM2.5 lagged value
  • Features: SO2, NO2, PM10, month, year, lagged PM2.5
  • Evaluation: MAE, RMSE on validation set
