Building Up GaME-T Objective:

Develop hydro-meteorological warning system associated with telemetry stations, and demonstrate the value of the warning system in Mae Waang, Chiang Mai, Thailand.

Ongoing Studies:Installation of 15 new AWS stations with telemetry

and continuation of a few flux measurement stations.Case study of an extreme event caused by a tropical

cyclone.Hydrological modeling coupled with atmospheric

weather forecast.

Data is logging every 5 seconds and recorded by averaging every 10 minutes.Tel-super system can storage data for 6 month, Tel-rain system can storage data for 1.5 month.

GSM is easily able to connect line directly by dial-up connection, although GSM (9.6 kbps) is low-speed access than GPRS (115 kbps).

Plan for the AMY-2008 NO research funding for field observation

project in Thailand/Indo-China Peninsula from Japanese side, so far.

Would like to continue:Flux measurement/AWS sites in ThailandStudy on hydrometeorological warning systemsData collection and integration in the Peninsula

An idea for AMY-2008:Combining TMD weather radar network with

THANKYOU!

Friends,the

hydrologists,can we fix it?Yes we can!
