Dr Shovan Kumar SAHU

Dr Shovan Kumar Sahu’s current role in CCRS includes research and development of air quality models to study the transport of air pollutants in the context of Singapore and Southeast Asia region, validate model outputs besides maintaining and operating the currently operational air quality models. He has previously worked on simulating air pollutants in the northern hemisphere, studies estimating health burden associated with pollutant exposure, source apportionment studies estimating contribution of regions and sources responsible for air pollution, effect of future climate change on air pollutants, studies using satellite-based data to estimate air pollutant concentration, use of artificial intelligence to replace traditional models and its use in updating emission inventory.
