**Dataset Information:**

- **Name:** Delhi Air Quality and Weather Data
- **Version:** 1.0.0
- **Description:**  
  This dataset contains **4.5M** records of hourly weather and air quality data from multiple locations across Delhi, India, collected over several years. The data spans from March 2000 to November 2024 and includes measurements from all 23 AQI monitoring centers in Delhi.
  The dataset provides environmental parameters such as temperature, humidity, atmospheric pressure, wind speed, wind direction, and concentrations of pollutants (PM2.5, PM10, NO2, SO2, O3, CO), along with the corresponding Air Quality Index (AQI).  
  It is useful for analyzing air quality, studying weather patterns, and tracking environmental trends in Delhi. The dataset covers various locations like PGDAV College, Sonia Vihar, Anand Vihar, and Pusa, among others.
