Automated Weather System

Context: Dr. Jitendra Singh, Minister for State for the Ministry of Science and Technology and Earth Science provided a written reply in Lok Sabha on Automated Weather Systems.

The Reply in Brief: The India Meteorological Department (IMD) constantly monitors and maintains the quality of data received from its network of Automated Weather Stations (AWS). The AWS is equipped with sensors for various meteorological parameters and undergoes regular maintenance to ensure the accuracy and quality of the data. This maintenance includes following guidelines set by the World Meteorological Organization (WMO), such as ensuring proper exposure conditions at AWS sites and comparing atmospheric parameters with sensor standards during calibration. If any AWS sensor does not meet the WMO criteria for accuracy, it is replaced with a new one.

What is an Automated Weather System?

An automated weather system (AWS) is a sophisticated and modernized weather monitoring system that uses advanced technology to collect, process, and disseminate weather-related data. An AWS consists of a network of weather sensors, such as thermometers, barometers, anemometers, and rain gauges, which are connected to a central computer system. The central computer system collects and analyzes the data received from the sensors to generate real-time weather reports and forecasts. 

How do Automated Weather Systems Work?

Automated weather systems use a combination of sensors and computer algorithms to collect and process weather data. The sensors are typically placed in strategic locations, such as airports, weather stations, and buoys, and are designed to measure various weather parameters, such as temperature, humidity, wind speed, and precipitation. The data collected by the sensors is transmitted to a central computer system, which processes the information using sophisticated algorithms to generate accurate and reliable weather reports and forecasts.

Benefits of Automated Weather Systems

Automated weather systems have several benefits over traditional weather monitoring systems. Firstly, they provide more accurate and reliable weather data due to the use of advanced technology and algorithms. This information is crucial for weather-dependent industries such as agriculture, aviation, and transportation. Secondly, automated weather systems provide real-time data, which enables rapid response in the event of severe weather conditions such as thunderstorms, hurricanes, and tornadoes. This is important for emergency services, government agencies, and other organizations that need to quickly respond to such events. Thirdly, automated weather systems are cost-effective compared to traditional weather monitoring systems, which require manual data collection and processing.


In conclusion, automated weather systems are a significant advancement in weather monitoring technology. They provide accurate, reliable, and real-time weather information, which is crucial for many industries and organizations. As technology continues to improve, automated weather systems will become even more sophisticated, providing even more accurate and detailed weather reports and forecasts. With the increasing frequency and severity of extreme weather events, having accurate and up-to-date weather information is more important than ever.
