Hao Huang and Bill Bloss recently completed measurements of atmospheric ozone production in India, at TERI University in Delhi, and IISER Mohali in Chandigarh, supported through a Royal Society exchange grant in collaboration with Dr Nandini Kumar (TERI) and Prof Vinayak Sinha (Mohali).

Overcoming the challenges of local logistics, 42C temperatures and much dust entering the instruments, a good series of measurements were obtained and the kit safely extricated back to Birmingham despite the Indian and UK customs services. The data obtained represent the first direct measurements of chemical ozone production in India, and demonstrate the application of this newly developed technique in a challenging environment, of relevance to better informing air quality policy to mitigate ozone-driven crop yield reductions.
