The National Institute of Ocean Technology (NIOT) has successfully tested an indigenously developed Floating LiDAR Buoy System off the coast of Muttom, Tamil Nadu. The development marks a significant step in enhancing India’s ocean-based meteorological and renewable energy assessment capabilities.

About Floating LiDAR Buoy System

The Floating LiDAR Buoy System is a state-of-the-art oceanographic instrument designed to measure wind and atmospheric conditions over the sea.

Key Features

• Combines a floating buoy platform with LiDAR (Light Detection and Ranging) technology.
• Uses laser pulses to capture highly accurate atmospheric data.
• Capable of measuring wind speed, direction, and vertical wind profiles.
• Can collect data up to 300 metres above sea level, surpassing many conventional instruments.

Working Mechanism

• The buoy is deployed on the ocean surface and remains stable under marine conditions.
• It emits laser pulses into the atmosphere.
• These pulses reflect off airborne particles such as aerosols.
• The returned signals are analysed to determine:
  • Wind speed
  • Wind direction
  • Variations at different altitudes

This enables real-time, high-resolution data collection, even in remote offshore regions where traditional meteorological tools face limitations.

Significance

1. Improved Weather Forecasting

• Enhances accuracy of marine weather predictions.
• Supports better storm and cyclone tracking, crucial for coastal safety.

2. Boost to Offshore Wind Energy

• Provides precise wind data necessary for site assessment of offshore wind farms.
• Reduces uncertainty in renewable energy planning and investments.

3. Climate Change Studies

• Helps monitor long-term atmospheric and oceanic interactions.
• Contributes to understanding the impact of climate change on marine systems.

4. Indigenous Technological Advancement

• Reflects India’s progress in developing advanced ocean observation systems.
• Reduces reliance on imported technologies.
