New Dashboard Tackles Air Pollution Crisis

The Indo-Gangetic plain and Himalayan foothills face a severe air quality crisis. Recent reports indicate that fine particulate matter (PM2.5) levels have reached alarming heights. In some areas, these levels are 20 times higher than the World Health Organization’s recommended limits. This persistent exposure poses health risks for millions of people in the region.

Air Quality Dashboard Overview

The International Centre for Integrated Mountain Development (ICIMOD) has launched an Air Quality Dashboard. This platform provides real-time and forecasted data on air pollution. It combines ground sensor data with satellite imagery. This integration offers a comprehensive view of air quality across local and regional scales.

Key Features of the Dashboard

One notable tool in the dashboard is a dynamic timelapse. This feature uses the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem). It illustrates the spread of PM2.5 plumes across the region. Hotspots like Lahore, New Delhi, and Kolkata have been identified. Between November 1-21, 2024, PM2.5 concentrations peaked at 300 µg/m³ in certain areas.

Health Implications

These hazardous levels of air pollution pose severe health risks. Air pollution was the second leading risk factor for early death globally in 2021. South Asia alone accounts for approximately two million premature deaths annually due to polluted air. The urgency for action is clear.

Regional Cooperation and Challenges

Transboundary pollution is challenge in the Indo-Gangetic plain and Himalayan foothills. Recent smog episodes have forced school closures in Lahore and parts of northern India. This marks the pervasive nature of the air quality crisis. Regional cooperation is essential to effectively tackle this issue.

and Forecasting

The WRF-Chem model allows users to explore the interaction between weather patterns and pollution sources. It integrates emissions data at both local and regional levels. This provides a clearer picture of pollution dynamics across borders. Users can also access two-day forecasts. This enables communities and policymakers to anticipate air quality conditions.

Importance of the Dashboard

The Air Quality Dashboard represents effort to encourage regional collaboration. By visualising pollution trends and providing actionable data, it equips stakeholders with valuable insights. Addressing air pollution is one of South Asia’s most pressing public health challenges.
