**Dataset Information:**

- **Name:** Processed Delhi Air Quality and Weather Data
- **Version:** 1.0.0
- **Description:**
This dataset contains **2.9M** rows of hourly weather and air quality data from multiple locations across Delhi, India, collected from March 2000 to November 2024. The data includes 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).
The data has been pre-processed for model training, including the following updates:
- Rows with AQI values marked as `"-"` have been removed, as they accounted for 15% of the total dataset.
- Missing values have been handled through various methods, including dropping, mean imputation, and nearest neighbor interpolation.
- Centers responsible for missing data have been identified and documented.
**This processed dataset is specifically curated for model training. For alternative uses or visualizations, you may refer to the unprocessed version of the dataset**.(abhinavsarkar/delhi_air_quality_feature_store_processed.csv)

**Data Quality:**

- The dataset has been cleaned to remove rows with AQI values marked as `"-"`, which constituted 15% of the data.
- Missing values have been handled by dropping, using mean imputation, or applying nearest neighbor interpolation based on the specific data column.
- Centers responsible for sending incomplete or missing data have been identified and are documented.
