1. What is the Regional Analysis of Indian Ocean (RAIN) System?

The Regional Analysis of Indian Ocean (RAIN) system is a sophisticated data assimilation system developed by the Indian National Centre for Ocean Information Services (INCOIS). It is designed to enhance the understanding and monitoring of the Indian Ocean's health through advanced oceanographic data.

a. Upgraded Version Features:

  • Previous Version: Focused on sea surface temperature and salinity.
  • Upgraded Version: Incorporates Sea Surface Height Anomaly (SSHA), improving the analysis of ocean currents and overall oceanographic conditions.
  • Data Collection: Observations are gathered from the surface and depths ranging from 3 meters to 2,000 meters, which helps in more accurate and comprehensive ocean current analysis.

b. Implementation:

  • Development Timeline: The upgraded version has been under development since 2023 and has been recently implemented.

2. Indian National Centre for Ocean Information Services (INCOIS):

a. Establishment and Structure:

  • Founded: 1999
  • Status: Autonomous body under the Ministry of Earth Sciences (MoES)
  • Affiliation: Part of the Earth System Science Organization (ESSO)

b. Mandate:

  • Primary Goal: To provide high-quality ocean information and advisory services.
  • Objectives: Support society, industry, government agencies, and the scientific community through continuous ocean observations and research.

c. Key Activities:

  • Tsunami and Coastal Warnings: Operates the Indian Tsunami Early Warning Centre (ITEWC), providing round-the-clock monitoring and warnings for tsunamis, storm surges, and high waves.
  • Designation: ITEWC is recognized by the Intergovernmental Oceanographic Commission (IOC) of UNESCO as a Regional Tsunami Service Provider (RTSP), offering tsunami warnings to countries around the Indian Ocean Rim.
  • Fisheries Advisory Services: Issues daily advisories to fishermen, helping them locate fish-rich areas efficiently, thereby saving fuel and time.

3. Significance of the RAIN System:

a. Enhanced Ocean Monitoring:

  • Improved Accuracy: The incorporation of sea surface height data into the RAIN system provides a more detailed understanding of ocean currents and conditions, crucial for accurate weather forecasting and climate studies.

b. Comprehensive Data Collection:

  • Depth Range: The system’s ability to gather data from a range of depths allows for a more complete picture of oceanographic conditions, from surface to deeper waters.

c. Support for Various Stakeholders:

  • Government and Industry: Provides essential data and advisory services to support decision-making and policy formulation.
  • Scientific Community: Facilitates research with high-resolution and comprehensive oceanographic data.
  • Public Services: Enhances coastal safety through early warning systems and supports the fishing industry with practical advisories.

4. Future Directions:

a. Continuous Improvement:

  • System Upgrades: Ongoing enhancements to the RAIN system to incorporate new technologies and methodologies for better ocean monitoring and data accuracy.

b. Expanded Services:

  • Broader Applications: Potential for integrating additional data layers and expanding advisory services to cover more aspects of oceanographic and climate research.

In summary, the RAIN system represents a significant advancement in oceanographic monitoring and data analysis, leveraging updated technologies to provide comprehensive insights into the Indian Ocean’s health. INCOIS, with its robust mandate and services, plays a crucial role in supporting environmental and safety initiatives in the region.
