  1. GEOSS And MAHASRIExperiment in Tropics(GaME-T) Taikan Oki and Shinjiro Kanae Institute of Industrial Science The University of Tokyo

  2. 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.

  6. Wind Speed & Direction 2.7m Air Temperature & Humidity 2.0m Short & long-wave radiation 1.0m Air pressure in Data logger box Rain Fall -5cm -10cm -20cm River Water Level : Soil Temperature : Soil Moisture -40cm Ground Water Level Instrumentation : Tel-super site NO.1 Making well at NO.4

  7. Air Temperature 2.0m 1.0m Data logger box Rain Fall -5cm : Soil Temperature Instrumentation : Tel-rain site NO.8 NO.13

  8. Air Temperature 2.0m Rain Fall 1.0m Data logger box Water Temperature River Water Level Instrumentation : Tel-rain site(with river level observation) NO.12 NO.11

  9. Instrumentation : Data acquisition and Telemetry system Data logger • 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 modem • 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). Data transfer every 1 hour from all observation sites GEOSS Data Server at RID Center 1 GEOSS Data Archive System at the Univerisuty of Tokyo

  10. NO12→NO2：60 min (r = 0.51) NO11→NO2：10 min (r = 0.79) NO11→NO6：250 min (r = 0.40) NO2→NO6：240 min (r = 0.54) NO12→NO6：310 min (r = 0.35) Lag analysis on water table No lag correlation NO7→NO6, NO2

  12. 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 Thailand • Study on hydrometeorological warning systems • Data collection and integration in the Peninsula • An idea for AMY-2008: • Combining TMD weather radar network with surface telemetry raingauge…revenge of IOP1998

  13. THANKYOU! Friends,the hydrologists,can we fix it? Yes we can!(at least in the future)
