Automatic Weather Stations in North-Eastern States

In news

India Meteorological Department (IMD) has installed modern Automatic Weather Stations (AWS) in North Eastern States of India

Details
  • In order to enhance the Weather & Climate services of the NE region, an activity namely, ‘Integrated Meteorological Services for the North-East (NE) region’ has been initiated by the Ministry of Earth Sciences (MoES) under the Central Sector scheme Atmosphere & Climate
  • Research-Modeling Observing Systems & Services (ACROSS).
  • Under the activity, entire observational network in the NE region will be augmented to improve the weather & forecasting skills over the region by commissioning of state of art systems like 8 X-Band Doppler Weather Radars, GPS sonde systems, Snow Gauges, and augmentation of Automatic
  • Weather Stations, Automatic Rain Gauges etc.
  • This will include setting of observational network required for meeting aviation & other requirements through commissioning of Automated Weather Observing System/Heliport Automated Weather Observing System (AWOS/HAWOS), setting up/upgradation of Meteorological Centres (MCs) and other facilities over the region.
Significance

Augmentation of the observational network will help fill the data gap areas in the region, leading to better accuracy of forecasts and consequent precision in Climate monitoring, analysis and climate prediction.

Automatic Weather Stations
  • An Automatic Weather Station (AWS) is defined as a facility that automatically transmits or records observations obtained from measuring instruments.
  • In an AWS, the measurements of meteorological elements are converted into electrical signals through sensors.
  • The signals are then processed and transformed into meteorological data.
  • The resulting information is finally transmitted the by wire or radio or automatically stored it on a recording medium.
