The data telemetry of JKEO1 is as same as of the
KEO. The following description is based on that in KEO web site. Data from the JKEO1 mooring are
telemetered in near-real-time via Service Argos utilizing the NOAA
polar-orbiting satellites. The buoy data are processed nightly at PMEL,
where calibration coefficients and quality controls are applied. In addition,
an Iridium Positioning System (IPS) transmits tension of the mooring line and
GPS position of the mooring once every three days. The
JKEO1 mooring transmits daily mean values from the previous day as well as
spot values of high resolution surface meteorological data that are
transmitted opportunistically. In order to reduce battery requirements and
Service Argos charges, the JKEO mooring transmits for 8 hours per day, from
2000-0000 and 0200-0600 UTC. Real-time
updates of daily mean data are made to the JKEO1 web pages on a daily basis.
Complete high temporal resolution data (10-minute or 2-minute depending on
sensor) will be available in delayed mode from the JKEO1 data delivery page. Since
May 22, 2007, daily mean ocean temperature and up to 4 hourly surface wind,
relative humidity and air temperature observations have been submitted onto
the Global Telecommunications System (GTS) by Service Argos. Delayed
mode Oceanic Data will be available also from the Japan Oceanographic Data
Center in Tokyo. Last updated on December 26, 2008 |
