Real-time air quality for Mumbai, forecast 24 hours ahead with anomaly alerts.

Time-seriesEnsemblesGeospatialAnomaly detection

Real-time air-quality monitoring and forecasting across Mumbai. A stacked ensemble combines spatial and time-series signals to predict 24 hours ahead, and an automated detector flags readings that don't fit the pattern.

Approach

  1. Continuous ingestion of station readings for live monitoring.
  2. Spatial features (station neighbourhoods) combined with temporal lags and seasonality.
  3. Stacked ensemble forecaster with 24-hour prediction windows.
  4. Automated anomaly detection that separates sensor glitches and pollution events from normal variation.
