Bharat Climate Observation Network (BCON)

Latest News

Recently, the Indian Institute of Tropical Meteorology (IITM), Pune, and the Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, signed a long-term Memorandum of Understanding (MoU) to establish a climate observation station in the Himalayan region under the Bharat Climate Observation Network (BCON).

About Bharat Climate Observation Network (BCON)

The Bharat Climate Observation Network (BCON) is a national climate observation initiative conceptualized and implemented by the Indian Institute of Tropical Meteorology (IITM) under the Ministry of Earth Sciences (MoES), Government of India.

The network aims to establish a long-term, high-precision climate monitoring system across the country by collecting reliable and continuous climate data. It will strengthen India's ability to understand climate variability, climate change, and their impacts on the environment and society.

Objectives of BCON

Develop Long-Term Climate Monitoring

The primary objective of BCON is to create a high-precision, long-term climate observation framework that continuously records important atmospheric and environmental parameters across different regions of India.

Support Climate Research

The network seeks to generate scientifically reliable climate datasets that help researchers understand long-term climate trends, improve knowledge of climate change, and support advanced scientific studies.

Strengthen Climate-Based Policy Making

BCON aims to provide evidence-based climate information to policymakers, enabling informed decisions related to climate adaptation, disaster risk reduction, agriculture, water management, and environmental planning.

Functions of Bharat Climate Observation Network

Monitoring Meteorological and Climate Parameters

BCON will continuously monitor a wide range of meteorological and climate-related parameters. These include temperature, rainfall, humidity, wind, soil moisture, greenhouse gases, short-lived climate pollutants, and various aspects of atmospheric chemistry.

This comprehensive monitoring will help in understanding both natural climate variability and human-induced climate change.

Creation of a National Climate Database

The network will develop a robust national climate database by collecting high-quality observational data from different regions of the country.

This database will support the detection of long-term climate trends, facilitate climate change research, and strengthen India's capacity for climate assessment and evidence-based policymaking.

Significance of Bharat Climate Observation Network

Improves Climate Models

The highly accurate datasets generated by BCON will serve as an important source for validating and benchmarking climate models.

These observations will significantly improve the performance of Earth System Models (ESMs), including India's first Earth System Model (IITM-ESM).

Enhances Climate Change Projections

Reliable observational data will enable scientists to produce more accurate simulations of India's climate and generate better future climate projections, which are essential for climate adaptation and mitigation planning.

Supports Disaster Risk Management

Continuous monitoring of atmospheric and climatic conditions will strengthen early warning systems for extreme weather events such as heat waves, heavy rainfall, floods, droughts, and cyclones, thereby improving disaster preparedness.

Strengthens Himalayan Climate Research

The establishment of a climate observation station in the Himalayan region is particularly significant because the Himalayas are highly vulnerable to climate change, glacier retreat, changing rainfall patterns, and extreme weather events.

Long-term observations will improve understanding of the region's climate dynamics and support sustainable management of Himalayan ecosystems.

Importance for India

The Bharat Climate Observation Network will strengthen India's scientific capability in climate monitoring, improve the accuracy of weather forecasting and climate prediction, and support national commitments related to climate resilience, sustainable development, and international climate reporting.

It will also provide reliable scientific evidence for planning in sectors such as agriculture, water resources, energy, forestry, and urban development.
