Atmospheric science experts from across the world congregated at Nainital, Uttarakhand discussed the changes in the greenhouse gases in the Earth’s atmosphere with implications on climate change and the importance of FTIR spectroscopy

Based observations from ecologically sensitive Himalayan regions for studies on the topic.

Aryabhatta Research Institute of Observational Sciences (ARIES), an autonomous research institute under the Department of Science & Technology (DST), Government of India is hosting the annual meeting of the. 

Network for the Detection of Atmospheric Composition Change (NDACC-IRWG), the Total Carbon Column Observing Network (TCCON), 

and the Collaborative Carbon Column Observing Network (COCCON) communities from June 16-20, 2025 at its Manora Peak campus.

The 5-day flagship meeting unites global experts and data users in ground-based Fourier Transform InfraRed (FTIR) spectroscopy associated with the Infrared Working Group of the NDACC-IRWG, TCCON and COCCON, 

all working to advance our understanding of atmospheric composition change.
