Introduction
India has achieved a significant milestone in aviation safety and weather monitoring with the inauguration of its first SkyCast System at Indira Gandhi International Airport (IGI), New Delhi. This integrated atmospheric remote sensing system marks India's entry into an elite group of nations possessing advanced weather observation capabilities for aviation operations.
Key Facts and Data Points
- Location: First facility at IGI Airport, New Delhi; next planned at Jewar Airport
- Global Positioning: India becomes the 19th country to deploy SkyCast technology (18 existing facilities worldwide)
- Altitude Coverage: Monitors atmospheric parameters up to 3 km altitude
- Operational Status: Fully functional at IGI Airport
Technologies Integrated in SkyCast
The SkyCast system combines multiple sophisticated atmospheric monitoring instruments:
- Radar Wind Profiler - Measures wind speed and direction at various altitudes
- SODAR (Sonic Detection and Ranging) - Uses sound waves to detect atmospheric conditions
- Microwave Radiometer - Measures atmospheric temperature and humidity profiles
- Ground-based Fog Aerosol Spectrometer (GFAS) - Specifically designed for fog detection and aerosol analysis
- CL61 Lidar Ceilometer - Measures cloud base height and aerosol layers
Scientific Foundation: Winter Fog Experiment (WiFEX)
The SkyCast system is not a new development but represents the operationalization of years of scientific research:
- Initiated: 2015 by IIT Madras and India Meteorological Department (IMD) at IGI Airport
- Focus Areas:
- Fog formation mechanisms
- Aerosol-cloud interactions
- Visibility reduction processes
- Urban boundary-layer processes
- Outcome: Enabled development of this operational forecasting system
Mission Mausam Integration
SkyCast is an integral component of Mission Mausam, India's initiative to strengthen weather observation and forecasting capabilities:
- Enhances aviation resilience across Indian airspace
- Expands scientific observation networks
- Integrates AI-enabled forecasting capabilities
- Incorporates aircraft-based data for comprehensive weather analysis
- Aims for safer and more reliable aviation operations
Benefits and Applications
Aviation Sector
- Real-time atmospheric intelligence for pilots
- Improved decision-making for air traffic operators
- Reduced flight delays, diversions, and cancellations
- Better management of fog, turbulence, and adverse weather events
Beyond Aviation
- Urban weather forecasting - Enhanced prediction for city-level weather
- Pollution management - Aerosol monitoring aids air quality assessment
- Transport advisories - Road and rail safety improvements
