Chennai’s two meteorological centres in Nungambakkam and Meenambakkam have been recognised as long-term observing stations by the World Meteorological Organisation.
They have been chosen among 5 other stations in India that have made weather observations for more than 100 years.
It is a recognition for maintaining 100 years of data that could be used as vital records to assess climate variability and understand changes in the climate system.
The first meteorological station in the country was established at Chennai in 1792.
