Weather can change every minute. For instance, Palavakkam may not experience the same rainfall as Nungambakkam. It is this gap in rainfall measurement and enthusiasm for weather tracking that led several bloggers to own their automatic weather stations (AWS).

It is the thrill of the device ticking with every drop of rain that led S. Shivakumar, a weather blogger from Anna Nagar, to own an automatic weather station. “I initially used a paint container as a manual rain gauge on my terrace. I bought the device for better accuracy. It is up to 95% accurate and recorded nearly 20 cm of rainfall during the recent rain spell,” he said. As the Meteorological Department’s network of weather stations and rain gauges is limited, weather enthusiasts are now keen on owing a weather station and often import devices to monitor weather in their locality. K. Ehsan Ahmed — who started the Keaweather site for amateur meteorologists — said nearly 20 weather bloggers who own AWS contribute rainfall data to the site.

“Several bloggers use Accurite AWS, that is affordable, to collect data on rain, wind direction and temperature. Some enthusiasts have installed sophisticated Davis Vantage Vue to manage weather data,” said Mr. Ahmed who was one of the first city residents to own an AWS.

The localised rainfall data also helps in assessing groundwater recharge. “I share the data with my apartment dwellers to encourage harnessing rainwater. It also helps in travel forecast,” said P. Harish Kumar of Chromepet.
