Every day, thousands of tiny readings quietly shape the forecasts we rely on—from the temperature you check before stepping out to the warnings that precede heavy rain or strong winds. Now, the India Meteorological Department (IMD) is giving this invisible network a technological upgrade. On the occasion of World Meteorological Day, the national weather agency announced the induction of a new digital surface meteorological observation system into its monitoring network, signalling a significant step toward modernising how India measures and tracks weather.
The system replaces traditional mercury-based instruments with digital sensors supported by Wi-Fi-enabled electronics. These sensors measure key atmospheric parameters including air temperature, humidity, atmospheric pressure, wind patterns, and rainfall. The information collected is geo-tagged and transmitted in real time, making it far easier for meteorologists and researchers to analyse weather patterns and respond more quickly to changing conditions.
