The real time data will be distributed on GTS (Global Telecommunication System) via French ARGOS global processing center. The data will be used by the meteorological agencies and institutions for ENSO monitoring, daily weather forecasts, so on. While the data come into JAMSTEC Mutsu Branch, data quality is checked daily and the checked data are sent to PMEL. This procedure is carried out by the TRITON Data Management System which is a comprehensive software packages for the TRITON data processing in Mutsu Branch. After receiving the TRITON data, PMEL integrates the TRITON data with TAO data, and creates a same format grid data. Then, JAMSTEC and PMEL distribute the data from both homepages.
5. Quality control of real time data
Quality check for the hourly TRITON buoy data, so called the real time data, which is transmitted to JAMSTEC Mutsu Branch, is executed 2 times a day, 09:25 and 15:00 in JST, automatically in the TRITON Data Management System. Criteria adopted in this system is based on the oceanographic and meteorological concepts. Though this checking system finds the erroneous data, it never changes the original data but only making a checking report. It illuminates the flagged erroneous data. After the automatic data checking software has run, the real time data are checked manually in detail every day for the flagged data in view of oceanographic and meteorological standpoints. Through this procedure, only the quality indices are changed for the erroneous data, but the real time data are never revised. Table 4 presents the items of the real time data quality control.
The data which is checked as above are transmitted to a server machine at JAMSTEC headquarters in Yokosuka at 18:00 every day, automatically. At this time, not only the hourly data but also the daily averaged data are transmitted to the server. This daily averaged data are sent everyday to PMEL for the TAO/TRITON data integration. The buoy status information is also automatically created and distributed via e-mail system every morning at 09:40. This e-mail contains the most recent exact buoy location and data transmission status to watch any emergent case in Yokosuka, and from any other remote sites.
6. TRITON buoy data on GTS and on Internet
TRITON buoy data will be distributed on GTS via French ARGOS global processing center in Toulouse the same as TAO data for daily weather forecasts. The GTS data are hourly averaged wind, air temperature, relative humidity, atmospheric pressure, and water temperature.
On internet, TRITON data will be distributed the same as TAO data. The display and distribution software for the combined TAO/TRITON data sets has been developed based upon the TAO software. These data will be distributed from both JAMSTEC and PMEL/TAO homepages. Examples of real time data display are shown in Figure 6, Figure 7, and Figure 8.
Akira SHOJI of Mitsubishi Heavy Industries who passed away on January 8, 1999, age 46, dedicated his last 5 years to design and develop the TRITON buoy data processing system. Without his superior work, TRITON data may have not yet come so successfully. Koichi TAKAO and all the staff of TRITON Team of Marine Works Japan Ltd. worked very hard and made successful deployments while they had encountered many technical problems and struggled to operate the TRITON buoy system in its pre-matured stage.
Mike McPhaden enabled smooth buoy technology transfer from PMEL to JAMSTEC, and PMEL-TAO members were so helpful to develop TRITON buoy system through the frequent discussions, cooperative TAO operation on JAMSTEC ship, training for JAMSTEC's technical staff at PMEL laboratory in Seattle, so on. Nancy Soreide leaded to develop TAO/TRITON integrated data distribution software. TRITON project has been financially supported by Science and Technology Agency, Japan.
