ACARR is housing a 32 m 3-layer Automatic Weather Station (AWS) as well as a 3 m AWS network for climate and boundary-layer meteorology. They are integral parts of forecasting and monitoring systems worldwide. These systems, typically measure the following parameters: Wind speed, Wind direction, Air temperature, Relative humidity, Barometric pressure, Precipitation, and Solar radiation. These are highly accurate, durable, research-grade meteorological monitoring stations, designed for a wide variety of demanding environmental applications. This portable tripod station is suitable for both long-term and temporary deployments on flat or uneven terrain.

This system includes high-quality sensors, which are needed for defensible data in environmental research, as well as critical operations dependent on continual weather monitoring. Meteorological variables measured can be used to calculate many weather-related algorithms such as evapotranspiration, growing-degree days, wind chill, dew point, and other weather-related parameters.

The Automatic Weather Station network has been developed by installing AWS at Neriamangalam, Cherthala, Maliankara, and Arakunnam.

Real time data-minute wise  is updated from  five stations  in ACARR server through GPRS modem.
