Automatic Weather Station (AWS)

               
 IMG 1435    IMG 1551

These automated stations have built in weather instruments with electronic sensors for measuring surface level air temperature pressure, solar radiation, rainfall, wind velocity and other weather parameters. The stations have integrated data banks for storage of recorder data for later retrieval. (please click here for location)

Automatic Rain Gauges


GEDC0282      GEDC0264
Automatic Rain Gauges is intended catch rainfall through a tipping bucket mechanism which gauge and registered water content and automatically sends the data to PAGASA’s database via wireless network. (please click for location)

 

 Automatic Aviation Weather Observation System (AWOS)

The AWOS helps pilots and aviation personnel make critical decisions by providing continuous, real time information and reports on airport weather conditions.

     

Radio Detection and Ranging (RADAR)

  IMG 01171     IMG 01421

A weather surveillance radar (WSR) is useful in locating precipitation and estimate its intensity and in determining the center of tropical cyclones. In addition to this capability, state- of- the-art Doppler radars are capable of estimating radial velocity which can be used to determine the wind strength of tropical cyclones as well as to analyse its structure.

Upper air observations 

  upper-air1      upper-air31  

Upper air observations are essential inputs in numerical weather prediction models since they provide a vertical profile of the atmosphere. Direct in-site measurements of air temperature, humidity and pressure with height are measured with balloon-borne instrument platform with radio transmitting capabilities called radiosonde, typically to altitudes of approximately 30 km. These data are crucial in the forecast for severe weather and for aviation route forecasts. The upper-air measurements are transmitted to a ground receiving station.
