Meteorological data relayed by aircraft goes down by 60% in India due to suspension of flights

New Delhi: The suspension of flights in India due to the coronavirus outbreak has led to a 60 per cent decline in the availability of meteorological data relayed by aircraft, Ministry of Earth Sciences Secretary M Rajeevan said on Thursday.
He told PTI that due to the reduction of air traffic across the world, the crucial meteorological data shared with air traffic controls by planes has gone down by 50-60 per cent globally. The air traffic controls in turn share data with meteorological organisations.
A scientist dealing with the aircraft relay data said the information is run in two models in India – the UK MeT office model and US' Noaa model – for coming out with forecasts.
"It does affect the quality of forecast, but then there are other sets of data that are used to forecast to bridge the gap," the scientist, who works with one of the institutions under the Ministry of Earth Sciences, added.
India Meteorological Department (IMD) Director General M Mohapatra said the data shared by the flights is used in forecast models, especially in the medium range in predicting weather over the span of 10 days.
