To enhance PAGASA’s weather data gathering capabilities, radar dopplers, automatic rain gauges (ARG) and automatic weather stations (AWS) were installed throughout the country. These ARGs and AWSs are automated version of the traditional weather station that enables measurements of parameters such as barometric pressure, atmospheric pressure, air temperature, relative humidity, wind speed and direction from remote areas using meteorological sensors attached to rechargeable batteries powered by solar panels. With the use of mobile technology, these stations report through the telecommunication networks.
