Description                          (Indicated Clearly the Brand or Model of Goods/Services Offered)

Title

Supply and Delivery of One Thousand Four Hundred (1,400) Pieces Radiosonde Transmitters – Vaisala RS41-SG – With Free Met Balloon

A

BACKGROUND

Upper- air soundings complete the required weather parameters in 3 dimensions these are necessary for the purpose of weather analysis and prediction. Its importance is so great that the equipment used should be of great quality such as the transmitters and weather balloons which measures the different weather parameters up to 12,000 meters above mean sea level and send these data to the receiving stations in the country. The upper–air soundings can be used to deliver a real time  data required for local-area weather forecast such as thunderstorm and  rainy days-to name a few. These can be of additional help in the formulation of localized weather forecast in the newly formed five (5) PAGASA Regional Services Divisions in NCR, Northern and Southern Luzon, Visayas and Mindanao.
